When choosing a charger, it is best to use a charger with correct charging termination devices (such as anti-overcharge time devices, negative voltage difference (-dV) cut-off charging and anti-overheating induction devices) to avoid shortening the service life of the battery due to overcharging. Generally speaking, slow charging can prolong the service life of the battery better than fast charging. 02) Discharge: a. The depth of discharge is an important factor affecting battery life. The higher the depth of discharge, the shorter the battery life. In other words, as long as the depth of discharge is reduced, the service life of the battery can be greatly extended. Therefore, we should prevent over-discharging the battery to a very low voltage. b. When the battery is discharged at high temperature, the service life of the battery will be shortened. c. If the designed electronic equipment cannot completely stop all current, if the equipment is left unused for a long time without taking out the battery, the residual current will sometimes cause the battery to be over-consumed and cause the battery to over-discharge. d. When using batteries with different capacities, chemical structures or different charge levels, as well as batteries of different old and new types, the batteries will discharge too much, and even lead to reverse polarity charging.
