18650 battery pack repair analysis

Lithium battery packs are often unusable due to damage to one or a group of batteries. At this time, the voltage and capacity at both ends of each group of batteries should be measured one by one. There is no voltage or the voltage is seriously low, and the capacity or discharge time is quite different (before There is a description of a single battery) and replace it with a battery with similar capacity and internal resistance. 2 Generally, after replacement, the lithium battery pack can be used until the life of other batteries is almost consumed. This partial replacement is generally relatively low-cost. It is also a commonly used method currently on the market. 3 The lithium battery must be equipped with a protective board to limit overcharge, overdischarge, short circuit, etc., which is beneficial to prolong the life of the lithium battery pack. 4 Lithium batteries must not be short-circuited, so be careful when testing. The charging must not exceed the rated voltage and current, and the charging time should not be too long. The 518650 lithium battery must be used with a protective board. Choose a quality-guaranteed lithium battery charger to extend the battery life.
