It is more important to charge a newly purchased rechargeable battery for the first time. Usually the
rechargeable battery will be set to the zero-charge no-load state when leaving the factory, so the new
rechargeable battery needs to be charged before it can be used. In addition, the previous charging and
discharging conditions directly affect the future life of the battery. The correct method of operation
should be to choose a regular way to charge steadily, and try to fully charge it after exhaustion
First of all, we must adhere to the principle of "empty and full", and strive to fully release the
electrical energy before each charge. A big disadvantage of nickel-cadmium batteries is the "memory
effect", that is, the battery will "memorize" the power charged in the current time, and the next time
it is recharged. It can only be charged to the capacity of the last memory, so, If the battery is
charged halfway before the battery is used up, and so on, the capacity of the battery will decrease.
Over time, the capacity of the battery will gradually become zero.
Secondly, prevent mixed charging and mixed use. Because the technology and battery capacity of
different manufacturers are different. Therefore, different brands or different models of the same
brand, capacity of rechargeable batteries cannot be mixed on the same charger, let alone mixed on the
In addition, do not frequently use fast charging, and do not charge the battery that has just been
used immediately, as this will affect or shorten the service life of the battery.
