• Unsuccessful load test attempts: While load testing your battery can be done in an automotive shop, you also have the option to do it yourself. Make sure your battery is fully charged and left to sit out for 12 hours before proceeding to release the residual charge and yield more accurate results on how it will perform under normal circumstances. Let’s use a 12v deep-cycle battery as an example. Once you start the test and it holds under load for a few seconds but the voltage eventually begins to drop or it instantly falls to 0, this is a sign that something is wrong with your battery. It’s referred to as an “open-cell” which may be a cause of either manufacturing flaws, sulfation, or extreme temperatures. - Source: Internet
• When boosting a battery, assure correct polarity. Advanced chargers and battery analyzers will not service a battery if placed in reverse polarity. A sleeping Li-ion does not reveal the voltage, and boosting must be done with awareness. Li-ion is more delicate than other systems and a voltage applied in reverse can cause permanent damage. - 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

• To answer this question, we will have to look at the making and formation of li ion batteries. Basically, lithium ion batteries are made of electrodes and electrolytes while they have no water in them, therefore, a freezing temperature is not going to bring a major effect on its working. Lithium ion batteries when kept in freezing cold temperatures, will require recharging before the next use because low temperatures slow-down the speed of ions inside it. Therefore, to bring them back in the movement, it requires to be recharged. By doing so, the performance of the battery will increase because a cold battery discharges slowly whole the hot ones kill the lithium battery cells faster. - 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
• Deep-cycle batteries come in different sizes and structures. There are 100Ah deep-cycle batteries, slimline deep-cycle batteries, and more. Nevertheless, proper care and maintenance are needed regardless of their type to maximise their function. Below are some of the ways you can keep your deep-cycle battery pack in its best state for long-lasting use. - Source: Internet
• “It’s like a very slow worm that inches its head forward and pulls its tail in to move nanometer by nanometer,” said Yi Cui, a professor at Stanford University and SLAC, and an investigator at the Stanford Institute for Materials and Energy Research. “In this case, it transports by dissolving away on one end and depositing material to the other end. If we can keep the lithium worm moving, it will eventually touch the anode and reestablish the electrical connection.” - Source: Internet

• The minimum voltage of many 12V LiFePO4 batteries is around 10 volts. The battery’s BMS should detect when the battery voltage falls to around 10 volts and trigger low-voltage cutoff. (Low-voltage cutoff is also called low-voltage disconnect, which you’ll sometimes see abbreviated LVD.) - Source: Internet
• When a battery enters Low-Voltage Disconnect, it needs to be jumped with another 12V source to “wake up” the battery. It’s important to jump the battery within 5 days of the battery going into LVD mode to preserve its lifespan. Leaving the battery at a 0% charge for too long can damage the battery and void your warranty. - 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
• Many chargers must detect a voltage of more than 5V coming from the battery to charge it, but many chargers are different, so be sure to check their user manuals for charging requirements. But in Low-Voltage Disconnect, a voltmeter will only read 0-5V from the battery because the BMS has disconnected it. So, sometimes you have to jump the battery before charging it, depending on the charger. - 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
• Some battery chargers and analyzers (including Cadex), feature a wake-up feature or “boost” to reactivate and recharge batteries that have fallen asleep. Without this provision, a charger renders these batteries unserviceable and the packs would be discarded. Boost applies a small charge current to activate the protection circuit and if a correct cell voltage can be reached, the charger starts a normal charge. Figure 1 illustrates the “boost” function graphically. - Source: Internet
• Low-Voltage Disconnect is a critical protection for your Battle Born batteries, and understanding it can save you a bit of head-scratching and a lot of money. If your batteries are going into LVD often, it may be a sign you should expand your battery system. If you have a Battle Born 50Ah 12V LiFePO4 battery, our 100Ah 12V battery is a great upgrade. Or you can buy another 50Ah battery and connect it in series or parallel, depending on your needs. - Source: Internet
• Check on the battery and connections once in a while. Make sure it’s free of dirt and grime. If you have a battery with removable caps on top, always see if it has enough electrolyte water to cover the battery plates. Examine the entire battery bank for signs of physical damage, inspect the terminals, screws, clamps, and check if there are loose connections. - Source: Internet

• LiFePO4 batteries in low-voltage cutoff enter a sleep mode to protect the battery cells from over discharge. LFP batteries in sleep mode can have very low voltage readings, usually less than 5 volts. You may think that the battery is dead, but really it’s just sleeping. - 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
• A battery’s voltage changes depending on its charge and discharge rate. Plus, LiFePO4 batteries have a relatively flat discharge curve from around 99% to 20% capacity. Because of these factors, it can be hard to estimate their state of charge from voltage alone. - Source: Internet

The following several articles will discuss in detail on the daily use and maintenance of lithium ion batteries. I believe that is also a topic of great concern to everyone. - Source: Internet
• Low-Voltage Disconnect is a feature of our internal Battery Management System (BMS), which comes inside all Battle Born batteries and has lots of other safety features programmed into it to protect your investment and preserve the life of your battery. When fully depleting a Battle Born battery, the BMS detects when the battery’s voltage falls below 10V, and it will disconnect the battery. This prevents any charge from leaving the battery to protect it from damage. Many people will think their Battle Born battery is dead, but it’s just in LVD and not sending out a charge. - 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
• 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

Your charger’s voltage should also match that of the battery’s and the manufacturer’s instructions on charging should always be followed to avoid damaging the battery and endangering yourself too. - Source: Internet
• Fully depleting any battery can ruin it. That is why our internal BMS is so essential to protect your battery. Many people who buy lithium batteries that don’t have an internal BMS usually buy an external one to monitor them. Lead-acid batteries often lack this protection and are vulnerable to complete ruination. - Source: Internet
• 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
• 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
• Always keep your battery fully charged (above 12.5V). Use a voltmeter to easily keep track of your voltage level and make sure you top it up every after trip. - Source: Internet
• Researchers at the US Department of Energy’s SLAC National Accelerator Laboratory and Stanford University have shown that isolated lithium is alive and highly responsive to battery operations, due to its dynamic polarization to the electric field in the electrolyte. They have designed an optical cell with a lithium-nickel-manganese-cobalt-oxide (NMC) cathode and a lithium anode. They also used an isolated lithium island in between as a test device that allowed them to track what happens inside a battery when in use, in real time. - Source: Internet
• Your LFP battery’s manual probably has a state of charge chart in it. Usually this chart is tailored to your battery, so it should take precedence over the ones above. Also, you’ll notice from the above picture how much some brands’ voltage charts can differ from the generic ones. - Source: Internet
• Step 8. Now, take the discharged battery and put in in the freezer for one whole day and night. Make sure the battery is enclosed in a bag that keeps it from getting wet. - 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
• 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.

• Do not boost lithium-based batteries back to life that have dwelled below 1.5V/cell for a week or longer. Copper shunts may have formed inside the cells that can lead to a partial or total electrical short. When recharging, such a cell might become unstable, causing excessive heat or show other anomalies. The Cadex “boost” function halts the charge if the voltage does not rise normally. - 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
• Now, if you have put the batteries on charge for too long and forgot to disconnect it from the power source, now it is time to cool it down immediately. By cooling I mean, the speed of the movement of ions should be decreased due to which temperature of the battery has increased. There are many ways suggested to cool down the batteries and one of the most famous one is freezing the batteries for some time. - Source: Internet
