1. Charging:
When selecting a charger, it is best to use a charger with proper termination devices (e.g., anti-overcharge time device, negative voltage difference (-dV) cut-off charging, and anti-overheating sensing device) to avoid shortening the service life of the battery due to overcharging. Generally speaking, slow charging can prolong the service life of the battery more than fast charging.

2. 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, by reducing the depth of discharge, the life of the battery can be greatly extended. Therefore, we should avoid over-discharging the battery to a very low voltage.
b. When batteries are discharged at high temperatures, the life of the battery will be shortened.
c. If an electronic device is designed in such a way that all current cannot be completely stopped, and if the device is left unused for a long period of time without the batteries being removed, the residual current may sometimes cause the batteries to be over-consumed, resulting in over-discharge of the batteries.
d. Mixing batteries of different capacities, chemical structures, or charge levels, as well as old and new batteries, can also cause excessive battery discharge, or even reverse charging.

3. Storage:
Prolonged storage of batteries at high temperatures will reduce their electrode activity and shorten their service life.

The self-discharge test of lithium battery is as follows: Generally, 24 hours self-discharge is used to quickly test its charge retention capacity, the battery will be discharged to 3.0V with 0.2C, and charged to 4.2V with constant current and constant voltage 1C, and the cut-off current is 10mA. After 15 minutes, the battery will be discharged to 3.0V with 1C to measure its discharged capacity C1, and then it will be charged to 4.2V with constant current and constant voltage 1C, and the cut-off current is 10mA. Measure the capacity C2 of 1C after 24 hours, C2/C1*100% should be more than 99%.

The main components of nickel-metal hydride batteries are: positive electrode plate (nickel oxide), negative electrode plate (hydrogen storage alloy), electrolyte (mainly KOH), diaphragm paper, sealing ring, positive cap, battery case and so on.

1) There is no battery leakage problem. The battery does not contain liquid electrolyte and uses colloidal solids;
2) Can be made into a thin battery: with a capacity of 3.6V and 400mAh, its thickness can be as thin as 0.5mm;
3) Batteries can be designed in various shapes;
4) The battery can be bent and deformed: the polymer battery can be bent up to about 900 degrees;
5) Can be made into a single high-voltage battery: a battery with liquid electrolyte can only produce a high-voltage polymer battery by connecting several batteries in series;
6) Since it is liquid-free, it can be combined into multiple layers within a single chip to achieve high voltage;
7) The capacity will be twice that of a lithium-ion battery of the same size.
