Under normal circumstances, new NiMH batteries generally have very little power. After purchase, the NiMH batteries should be charged before use. However, if the battery has a short time from the factory and the power is sufficient, it is recommended to use it first and then charge it. The newly purchased Ni-MH battery generally needs to be charged and used 3-4 times before the performance of the Ni-MH battery can be brought into full play.

Although the memory effect of the NiMH battery is small, it is best to recharge it after each use, and it is fully charged at one time, do not charge for a while and then recharge. This is an important point of "longevity". When charging, pay attention to the heat dissipation around the charger. Keep the battery clean when not in use, especially the contacts at both ends, and wipe with a soft dry cloth if necessary. If the battery will not be used for a long time, remove the battery from the battery compartment and place it in a dry environment. After being stored for several months, NiMH batteries will enter a "sleep" state, and the battery life will be greatly reduced. If the NiMH battery has been placed for a long time, it is recommended to charge it with a slow charge first. Generally, the voltage of NiMH battery is below 1.2V before charging, and the normal voltage is about 1.4V after full charge. This can determine whether the battery is fully charged.
