Can You Overcharge Nimh Batteries. Trickle charging is similar to standard. I had an old 84v NiMh battery pack used in RC vehicles that had a bad cell and the pack overall became useless.

Put simply this means that once the battery is fully charged you stop charging it. The voltage of one cell will be 14 voltsAs one answer mentioned. Correct charging of these types of batteries also can give them a longer battery life.
You need to make sure the current doesnt go above this level it needs to be below 005C where C 800 mA.
Overcharging older NiMH batteries can also cause hydrogen to build up inside the cells. To maintain the performance of your Ni-MH batteries charge them correctly. You need to make sure the current doesnt go above this level it needs to be below 005C where C 800 mA. Overcharging these batteries can cause them to overheat and lower overall battery capacity.
