What is the rate discharge of the battery? What is the hourly rate discharge of the battery?
Rate discharge refers to the rate relationship between discharge current (A) and rated capacity (A•h) during discharge. Hourly rate discharge refers to the number of hours required to discharge the rated capacity according to a certain output current.
Can batteries of different capacities be combined?
If different capacity or old and new batteries are used together, there may be liquid leakage, zero voltage, etc. This is due to the difference in capacity during the charging process, which causes some batteries to be overcharged during charging , and some batteries are not fully charged, and have capacity during discharge. High batteries are not fully discharged, while low capacity batteries are overdischarged, in such a vicious cycle, batteries are damaged and leak or low (zero) voltage.
What are the main factors that affect the battery life?
01) Charging:
When choosing a charger, it is best to use a charger with proper charging termination devices (such as an overcharge time prevention device, a negative voltage difference ( -dV ) cut-off charging, and an anti-overheating induction device) to prevent the battery from shortening its 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 life of the battery. The higher the depth of discharge, the shorter the life of the battery. 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, or even reversed charging.
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.
