Common Lithium Battery Issues and How To Fix Them

Modified on Sun, 02 Jul 2023 at 12:36 AM

Low voltage


Low voltage in batteries can either be caused by high self-discharge or uneven current. You can solve fix this simply by charging the bare lithium battery using a charger with over-voltage protection. Make sure to use a suitable charger and not a universal one to ensure maximum safety. 


High internal resistance


A battery with high internal resistance causes it to heat up and the voltage to drop. It usually happens due to extended storage time, which can also lead to excessive capacity loss. You can try to solve this by activating your battery through the charging and discharging method. 


Battery expansion


Unfortunately, the only thing left to do with a swollen battery is to dispose of it. A swollen battery can be dangerous and is often caused by overcharging. See to it that you monitor your charging process to avoid charging for more than 12 hours. 


Capacity loss


Over-discharging is usually the root cause of the capacity decline in lithium batteries. In case you over-discharge your battery, it's better to use a smart charger for topping them off. Charge it very slowly at first while constantly checking if they're getting hot, then gradually increase the charge rate. However, if after restoring you notice that the battery heats up too much, you might have to replace it already. 


Not charging 


If your battery is plugged in but not charging, it could be due to a faulty charger, BMS failure, or charging system damage. You can try charging it with a low-voltage charger first and switching to its original charger afterwards. If none of the above-mentioned issues is present in your battery but it’s still not accepting a charge, this could be a sign of permanent damage.
