How to charge Ni-MH battery? The charger will not automatically cut off the power and use the battery. If the voltage is low, it doesn't seem to discharge … in case there is still some time to charge.

Ni-MH battery, Ni-Cd battery and lead battery are not afraid of overshoot, so the charger does not need to cut off power by itself. On the other hand, lithium batteries are particularly resistant to overshoot and must be powered off when fully charged. Both Ni-MH battery and Ni-Cd battery have internal memory, and the usage is that they can only be charged when they are used up, and then charged when they are used up. Otherwise, if you use half or half, the capacity will be half of the original. Lead-acid batteries are characterized by anti-memory effect, vulcanization after discharge, and no timely washing. The principle of lead-acid batteries is to charge as much as possible. This is especially suitable for automobile batteries.
