68 Unexpected Facts About How To Test If A Lithium Battery Is Dead | LiFePO4 Battery Voltage Charts (12V, 24V & 48V)

• Steingart was intrigued by how the bouncing changed as batteries discharged — it was not a linear increase. Instead, the height rapidly increased and then leveled off. His research team has been working for some time on internal changes related to battery discharge, and he wondered whether the changing bounces reflected an important change in the batteries. - Source: Internet
• Update: It appears that the drop test differences seen in the videos above may have more to do with the brand of battery than the batteries’ level of charge. Consider this test “probably bogus.” - Source: Internet
• If a lithium-ion battery is discharged below 2.5 volts per cell, a safety circuit built into the battery opens and the battery appears to be dead. The original charger will be of no use. Only battery analyzers with the boost function have a chance of recharging the battery. - Source: Internet
• In most cases, the voltage across a battery can be measured to check if a battery is working or dead. But if the goal is to ensure whether the battery can supply sufficient current to a load, make sure to measure the amperage of the battery in milliampere-hour (mAh). Batteries are rated in amp-hours and voltage. Check the battery’s label to determine the voltage and amp-hours of the battery. For example, 12V 95Ah means the battery provides 12V at 95 Amperes for an hour. - Source: Internet
• But 100% charging isn’t a big deal in small doses. If you are planning a long trip and will be heading out shortly after you finish charging, a 100% charge will have very little impact on your battery’s lifespan. However, if you will be leaving your battery unused for many days or weeks, a charge level of between 30-60% is much healthier for the batteries over the long-term. - Source: Internet
• The bigger heat issue that you have more control over is heat during charging. Even for cars with active battery cooling, the battery still heats up considerably during charging, especially when charging at high rates or supercharging. While supercharging is convenient when you need to get back on the road quickly, it is terrible for battery life if performed often. To make your battery last as long as possible, you should try to charge at lower rates, which keeps the battery cooler and happier. A longer charge each night is much better than supercharging over lunch each day. - Source: Internet
• There are a lot of negative effects of a bad battery on the device it is used to power. In situations where you leave a bad battery in a device, it will enhance the bulging and swelling up of the device. Also, when charging a bad battery, the effect of the battery on the device will instigate an unfavorable rise in the temperature of the device which usually leads to overheating. - Source: Internet
• “The zinc starts out as a packed bed of particles that all move very nicely past each other,” Steingart said. “When you oxidize the zinc, it makes bridges between the particles and makes it more like a network of springs. That is what gives the battery its bounce. " - Source: Internet
• Several factors could instigate the weakness or destruction of a battery. A battery might get damaged as a result of poor maintenance, or as a result of aging. Some batteries have a long cycle life, such as lithium-ion batteries, which can reach 4,000 cycles. While some batteries have a shorter cycle life, such as lead-acid batteries, whose capacity decays to 80% after 500 cycles - Source: Internet
• Victron Battery Balancer Victron Battery Balancer Victron makes a product that can help balance multiple series-connected 12 Volt lithium-ion batteries. Their Battery Balancer measures the Voltage of each 12V battery during charging, and bypasses 1 Amp of the battery with the higher Voltage, to the battery with the lower Voltage, until they are equal. It takes one Battery Balancer for a 24 Volt battery bank, two for a 36 Volt bank, and three for a 48 Volt bank. Victron Battery Balancer - Source: Internet
• For example, recall that when I checked my battery’s voltage with a multimeter at the battery terminals, I got a voltage reading of 13.23 volts. That correlates to a roughly 80% state of charge. - Source: Internet
• A fully charged 12V LiFePO4 battery will have a charging voltage of around 14.6 volts and a resting voltage of around 13.6 volts. - Source: Internet
• Checking battery capacity this way is convenient. But beware that it can be quite inaccurate. I generally use this voltage reading just to make sure my battery isn’t close to being fully discharged. - Source: Internet
• NEC is developing an organic radical battery (ORB) that is environmentally friendly since they use organic radical polymers instead of metals to provide electricity. ORBs may become a high-power alternative to the Li-ion battery within five years. SOURCE: NEC - Source: Internet
• Unlike NiCad batteries, lithium-ion batteries do not have a charge memory. That means deep-discharge cycles are not required. In fact, it’s better for the battery to use partial-discharge cycles. - Source: Internet
• There is one exception. Battery experts suggest that after 30 charges, you should allow lithium-ion batteries to almost completely discharge. Continuous partial discharges create a condition called digital memory, decreasing the accuracy of the device’s power gauge. So let the battery discharge to the cut-off point and then recharge. The power gauge will be recalibrated. - Source: Internet
• Knowing how to test a battery using a multimeter is important to ensure the battery is working at optimal levels and is not showing symptoms of wearing out. A battery failure can lead to seemingly increasing problems in the hardware of an electronic system or starting troubles in a car. A multimeter can be used to check the voltage and current produced by a cell which helps to recognize a faulty battery that may be replaced. The symptoms of a poor battery and how to test a battery with a multimeter are discussed below. - Source: Internet
• There is a sneaky issue that can crop up when using charging sources that potentially provide a high Voltage: When the battery is full the Voltage will rise, unless the charging source stops charging. If it rises enough the BMS will protect the battery and disconnect it, leaving that charging source to rise even more! This can be an issue with (bad) car alternator Voltage regulators, that need to always see a load or the Voltage will spike and the diodes will release their magic smoke. This can also be an issue with small wind turbines that rely on the battery to keep them under control. They can run away when the battery disappears. - Source: Internet
• In today’s world, batteries play a key role in energy storage and the production of electricity. Batteries are the power source for most devices, including phones, laptops, cars, solar panels, power bikes, television, and many other gadgets. Why does someone else’s battery last so long, while my own battery quickly fails. - Source: Internet
• If the car is off, a reading of 12.2 V-12.6 V shows that the battery is in good condition and fully charged, and if the measured voltage is less than 12.2 V, the battery is weak and may have to be replaced. - Source: Internet
• It doesn’t take long to learn what helps preserve the current charge on the battery. What’s not well known is how to care for the battery itself. That’s just as important. Doing so allows the battery to operate efficiently. Here are a few ways to keep your lithium-ion batteries healthy. - Source: Internet
• Beyond ionic liquids is a vast variety of alternatives, some nearing maturity and some just getting started. A few we left out because of their limited applications, such as the Aqueous Hybrid Ion (AHI) battery from Aquion Energy which is primarily for grid-sized applications. For safer Li-ion substitutes for mobile applications check out the slideshow to see just the highlights of what is available now and promised in the future. - Source: Internet
• For most conditions (over-current, over-Voltage, under-temperature, or over-temperature) the BMS will automatically switch back on again, either after a set amount of time has passed, or once the conditions are safe. However, there is one case where the BMS will NOT switch on by itself, the battery will stay off: When any cell within a LFP battery falls below the lower safe Voltage limit the BMS will switch off to protect the cells from over-discharge. It does this with still a little charge left in the cells, so the battery can sit for a while and self-discharge before damage to the cells occurs. The important part is that the BMS will not switch the battery back on by itself! When this happens the battery simply “goes away” and produces 0 Volt. - Source: Internet
• If the battery is at a voltage of 1.5V or lower, do not try recharging it. Over long periods of time a build of copper shunts can result within the battery which can cause shorts, leading to excessive heating which could result in the worst case scenario of an explosion. - Source: Internet
• Yet another Li-ion successor battery is being developed by SolidEnergy Systems using a solid electrolyte design similar to that being developed by Dyson, General Motors and Khosla Ventures when they purchase University of Michigan spin-off Sakti3. The SolidEnergy Systems next-generation Li-ion battery uses an “anode-free” lithium metal battery with dual-layer electrolytes and an ultra-thin lithium metal anode, which both companies claim is safer than today’s Li-ion.

• When the vehicle is turned on, the battery drives the starter motor, so more power is drawn from the battery. The voltage rating drops for a moment as soon as the car is turned on, but it shouldn’t get below 10 V. If the measured voltage is below 10 V, the battery may not have sufficient turnover strength and may be prone to failure soon, hence may be either recharged or replaced. - Source: Internet
• The maximum voltage that a lithium-ion battery is capable of producing is 4.2V, however this will soon drop to its nominal voltage of 3.7V. - Source: Internet
• Lithium-ion batteries are a huge improvement over previous types of batteries. Getting 500 charge/discharge cycles from a lithium-ion battery is not unheard of. Just follow the above guidelines. - Source: Internet
• Once a battery enters sleep mode, it needs to be woken up. Refer to your battery manual for how to do this. It usually involves jump starting it with another 12V battery. - Source: Internet
• If you can, disable float charging on your charge controller or battery charger. If you can’t, prevent the battery from entering float charge by setting the float voltage to that recommended in the battery manual — usually 13.6 volts ± 0.2 volts. - Source: Internet
• If the charging of one battery poses a lot of difficulties e.g. when the charging time becomes increasingly longer. If it takes double the amount of time to charge a battery compared to other batteries of the same type, it is recommended to replace that particular rechargeable battery. - Source: Internet
• Most people don’t use their entire electric vehicle battery pack capacity every day, and rarely have the need to charge all the way to 100%. By charging a lithium-ion battery to 80%, the lifetime of the battery can be as much as doubled, according to Grin Technologies. This Canadian company performed such tests while developing an adjustable charger designed for electric bicycles and other light electric vehicle batteries. - Source: Internet
• If you want to learn more specifics about the death process of lithium-ion battery cells, I highly recommend watching Professor Jeff Dahn’s lecture on the subject. Jeff Dahn is the leader of Tesla’s battery research partnership with Dalhousie University, and his student protegé now leads Tesla’s battery longevity program. His lecture is over one hour-long, but is well worth it if you’re a battery nerd like me. - Source: Internet
• But when I connected my battery to an MPPT charge controller, the controller measured 13.0 volts. That correlates to a roughly 30% state of charge — a difference of 50%! Granted, some charge controllers have much more accurate battery voltage readings than others. - Source: Internet
• A car battery is usually located in the engine compartment towards one side of the engine, but can also be placed under the wheel well, the back end of the car, or even in the trunk. Refer to the owner’s manual in case of any confusion regarding the battery location. Also, access the battery terminals by looking for metal connections on the top or front of the battery. Perform the following steps sequentially to check the voltage across the car battery when the car is off: - Source: Internet
• They found out it had to do with the way the batteries produce power. Electricity is generated by a chemical reaction inside the batteries as zinc changes to zinc oxide. Initially, a layer of zinc surrounds a brass core in the battery like a donut around a hole. As the battery discharges, the zinc donut gradually changes to zinc oxide. - Source: Internet
• Lithium-ion batteries are expensive, and large battery packs such as those in everything from electric cars to electric motorcycles and e-bikes usually make up the single largest cost of the entire vehicle. So it makes sense that you’d want to ensure your batteries live as long and happy a life as possible. Join Electrek as we take a look at why lithium-ion batteries die, and how you can increase and even double the lifespan of your batteries. - Source: Internet
• Note: Some batteries have higher cutoffs, such as 10.6V. So the limit in your battery manual may not be exactly 10V. - Source: Internet
• While it is important to understand the above in case problems arise, in practice we have found lithium-ion batteries to behave quite well. Even when connected in series. Just follow the guidelines we just talked about and you will likely be just fine! - Source: Internet
• The first thing you should do is to avoid letting your battery get hot. Fortunately, many electric vehicles go part of the way there. Tesla’s vehicles and the Chevy Bolt/Volt all use active cooling to keep the battery from overheating, though the Nissan Leaf relies on passive air cooling to keep the battery cool, making battery heat an even larger factor for those vehicles. - Source: Internet
• That means between 20 and 25 degrees C. The worst thing that can happen to a lithium-ion battery is to have a full charge and be subjected to elevated temperatures. So don’t leave or charge your mobile device’s battery in your car if it’s hot out. Heat is by far the largest factor when it comes to reducing lithium-ion battery life. - Source: Internet
• You can buy individual LiFePO4 battery cells online. They’re best used for making your own lithium batteries. You can connect cells in series and parallel to make LFP batteries with your desired voltage and capacity combinations. - Source: Internet
• Aluminium-ion batteries work like lithium-ion batteries, just using an inexpensive aluminum anode instead of an expensive lithium anode. The down side is that the theoretical maximum voltage for an aluminum-ion battery is 2.65 volts compared to four volts for lithium-ion batteries. However, on the up side the theoretical energy density of aluminum-ion batteries is 1060 Wh/kg, over twice as much as lithium-ion batteries at 406 Wh/kg (aluminium ions have three valence electrons while lithium-ions only have one).

• In today’s mobile world, battery life is precious. If you don’t believe me, go to an airport and watch the road warriors. It can get downright nasty when two spot the only available outlet at the same time. - Source: Internet
• Batteries deteriorate over time, whether they’re being used or not. So a spare battery won’t last much longer than the one in use. It’s important to remember the aging characteristic when purchasing batteries. Make sure to ask for ones with the most recent manufacturing date. - Source: Internet
• The typical 12 Volt 100 Ah battery would, for example, have a limit of 100 Amp continuous output current. That translates to (roughly) 12 x 100 = 1,200 Watt. Connect a 4,000 Watt inverter and you are guaranteed to never reach that level of output power! After 1,200 Watt the BMS will intervene and switch the battery off. It would take at least 4 of these batteries to be able to drive an inverter of this size and actually reach full continuous output! - Source: Internet
• Drop each battery (with the flat, negative end down) from a couple of inches up. If the battery is charged, it should make a solid thud and most likely stay standing. If, however, the battery is dead, it will bounce and fall over immediately. - Source: Internet
• For the most part, these simple methods can greatly increase the lifespan of your battery, and are easy to implement. Avoid supercharging your electric car unless necessary. Park your e-bike in the shade when available. Don’t leave your laptop and phone sitting in the sun or your hot car, and avoid charging your lithium-ion battery powered devices to 100% if possible. - Source: Internet
• After all, voltage drops under load. And a charge controller is a load. If I were to connect a solar panel and start solar charging the battery, its voltage would instantly jump. - Source: Internet
• I’ve always had an extra battery for my notebook, but it would never last as long as the original battery. I know now that it’s because I was storing the battery fully charged. That means oxidation of lithium-ion is at its highest rate. Storing lithium-ion batteries at 40 percent discharge and in the refrigerator (not freezer) is recommended - Source: Internet
• Theoretically yes, though LiFePO 4 batteries aren’t quite as affected by high charge levels as the rest of the lithium-ion lineup. But generally speaking, these rules apply to all lithium-ion batteries from your electric car to your cell phone and even your electric tooth brush. Professor Dahn even jokes that you’d be well advised to keep your laptop in the fridge when you’re not using it, if you really want to get extreme about increasing your battery life. - Source: Internet
• “The zinc oxide begins to form on the outside and it pushes its way to the core,” Steingart said. “As you get more and more zinc oxide, and the zinc oxide begins to appear everywhere in the zinc layer, the battery gets bouncier and bouncier.” - Source: Internet
• A battery can be prevented from unwanted damages through good management and maintenance. Proper charging will help your battery go a long way. If a battery is kept unused for a long time, it may cause damage to the electrolyte that serves as a conductor inside the battery, leading to the damage of the energy storing capacity of the battery itself. - Source: Internet
• I like this method best for estimating the state of charge of an LFP battery I’ve just received or just pulled out of storage. The battery is already at rest and not connected to anything. I find it too inconvenient to disconnect everything once the battery is in use. - Source: Internet
• Current methods of battery recycling require expensive and energy-consuming processes to separate and purify the materials before they can be reused. Lithium-ion batteries can be recycled either by processing the whole battery, or dismantling the cells before starting the recovery process. The latter has been more popular, but the dismantling can be a laborious process without the proper equipment available. - Source: Internet
• The high-temperature ionic salts are being developed for grid-sized batteries, but the low-temperature versions are being adapted to mobile applications, thus making them nonflammable, according to chief technology officer (CTO) Surya Moganty, at Nohms Technologies. Ionic salts produce no flammable by-products and basically all they need to be successful is the engineering optimizations necessary to make them outperform Li-ion. Sumitomo, for instance, has a salt-based battery that is molten at 142°F, which they claim requires half the space of Li-ion batteries. - Source: Internet
• However, when batteries get old, their potential to power devices reduces over time. When a battery is getting weak or dying, it gives signals (bad battery symptoms). However, many people only use their device daily, they are not familiar with the bad battery symptoms batteries give. - Source: Internet
• Unlike lead-acid batteries that can (briefly) deliver hundreds and even 1000+ Amps in current, there is a hard limit to what the BMS in a lithium-ion battery will allow. There usually are several stages; this much for a fraction of a second, that much for a few seconds, and some lower limit for long periods of time. Exceeding those limits means the BMS will switch off, and the battery “goes away”. This affects the loads you can bolt onto a lithium-ion battery. - Source: Internet
• The Nickel-Lithium battery has a non-flammable electrolyte called LISBON (LIthium Super Ionic CONductor, Li2+2xZn1-xGeO4) which can store up to 3.5-times the energy per pound of today’s Li-ion batteries, but requires a large investment to be developed into a replacement for Li-ion.

• A dead battery is not necessarily a bad battery, because it can still be recharged. When a battery is bad, it is in a situation that even when charged, it will instantly lose all its charges. If a battery is giving bad battery symptoms, it is believed to be in a stage where replacement is unavoidable. - Source: Internet
• Just as lithium-ion (Li-ion) replaced nickel metal hydride (NiMH) before it and nickel cadmium (NiCd) before that, silver zinc (AgZn) batteries are on track to replace Li-ion too, according to a McGraw-Hill forecast as far back as 2010. Since then silver zinc has been perfected and are on the market for rechargeable hearing-aid “button” batteries by ZPower LL (Camarillo, Calif.) They are nonflammable and could provide up to 40 percent more run time than lithium-ion batteries. SOURCE: ZPower - Source: Internet
• Unfortunately I don’t know of any cell phones or laptop manufacturers that make 80-90% charging easy, likely because they’d rather just sell you a new product in a couple of years. But if you won’t be using the device for a while, make sure it isn’t charged all the way up before your turn it off and stick it in a drawer. Your battery will thank you. - Source: Internet
• That means you HAVE to make sure that all batteries are at the same State-Of-Charge (SOH) before connecting lithium-ion batteries in series! The easiest way to ensure this is by fully 100% charging each battery before they are connected in series. For a set of 12V batteries that means (for example) using a 120V AC charger plugged into the grid or a generator, set it to an absorb Voltage of 14.4V, and let it charge until no more current goes into the battery. Repeat this for each battery, and only then connect them series. Depending on how well they match this may need to be repeated every now and then (once a year or so) though reports are encouraging that a group of series-connected batteries will continue to behave well over time, as long as they started out at the same SOH. - Source: Internet
• “My solar charge controller already measures battery voltage. I can just use it to check battery capacity.” - Source: Internet
• So, at what voltage is a Lithium-Ion battery considered dead? The voltage at which a Lithium-Ion is dead is around 3.4 volts. This voltage can vary depending on factors such as the temperature and also its manufacturer. Lithium-Ion batteries should not be used when they are dead. They contain a cutoff circuit to protect them from being used past the voltage at which they have lost all its charge. - Source: Internet
• I measured a battery voltage of 13.23 volts with my multimeter — roughly 80% state of charge. But the charge controller measured a battery voltage of 13.0 volts — roughly 30% state of charge. If you use your charge controller’s voltage measurement to check LiFePO4 battery capacity, you can be way off! - Source: Internet
• Battery monitors track the amount of amp hours consumed to accurately estimate the state of charge. They also display useful system specs such as battery voltage and current. Some connect via Bluetooth to your phone so you can check your LiFePO4 battery’s capacity in a mobile app. - Source: Internet
• A battery just like your devices (phones, laptops, solar panels), requires proper management. When a battery gives bad battery symptoms, do the needful by charging it properly. If after charging the symptoms persist, quickly get the battery replaced. - Source: Internet
