What Are The Main Factors That Affect Battery Life?

01) Charging:

When choosing a charger, it is best to use a charger with proper charging termination devices (such as anti-overcharge time device, negative voltage difference (-dV) cut off charging, and anti-overheating induction device), so as not to shorten the battery life due to overcharging. Generally speaking, slow charging can extend the 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 life of the battery can be greatly extended. Therefore, we should avoid overdischarging batteries to extremely low voltages.

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 not used for a long time without taking out the battery, the residual current will sometimes cause excessive consumption of the battery, resulting in over-discharge of the battery.

d. When using batteries of different capacities, chemical structures or different charging levels, as well as old and new batteries, the batteries will be discharged too much, and even reversed charging will occur.

03) Save:

If the battery is stored at high temperature for a long time, the electrode activity will be attenuated and the service life will be shortened.
