What are the main factors that affect battery life?

01) Charging:

When choosing a charger, it is best to use a charger with a correct termination of charge device (such as anti-overcharge time device, negative voltage difference (-dV) cut off charge and anti-overheat induction device), so as not to shorten the service life of the battery due to overcharge. Generally speaking, slow charging can extend the service life of the battery more than fast charging.

02) Discharge:

a. The depth of discharge is the main factor affecting the 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 avoid putting the battery too low voltage.

b. When the battery is powered down at high temperature, the service life of the battery will be shortened.

c. If the designed electronic device cannot completely stop all current, if the device is left unused for a long time without removing the battery, the residual current will sometimes cause excessive consumption of the battery, resulting in over-discharge of the battery.

d. The use of batteries with different capacities, chemical structures or charging levels, as well as the mixing of old and new batteries, will also cause excessive discharge of the battery, and even cause reverse charging.

03) Storage:

If the battery is stored at high temperature for a long time, its electrode activity will decay and shorten its service life.
