Nickel cadmium batteries, as a type of DC powered battery, can maintain charging and discharging for hundreds of times under normal use. However, the disadvantage is that if not used correctly, it is easy to lose its original power and may damage the battery. So, the battery editor from lithium iron phosphate battery manufacturers will introduce to you what to do if nickel cadmium batteries cannot be charged.

　　After using the battery for a certain period of time, we may find that it cannot be fully charged, which may result in the following possibilities:

　　1. The repeated "memory effect" leads to the continuous reduction of battery power to very small amounts;

　　2. Damage to the internal structure of the battery;

　　3. The battery experienced additional reactions due to uncontrolled heat during use;

　　4. The service life is too long, with charging and discharging exceeding 500 times.
