4 FAQs about Afghanistan container NiMH battery cbc47 charging

How to charge NiMH nickel metal hydride batteries?

Unfortunately charging NiMH nickel metal hydride batteries is not as easy to achieve compared to other types of cell or battery. The NiMH cells, like NiCds require charging using a constant current. The rate of charge is normally specified on the case of the cell and this rate should not be exceeded.

Do NiMH batteries overcharge?

As NiMH batteries are highly sensitive to overcharging, it is crucial to reasonably control the charging process for extending battery life. At this stage, the charger charges the battery at a constant current (usually 0.1C to 1C), and the battery voltage gradually rises.

How to charge a NiMH battery?

Temperature management is also a key factor in the charging process of NiMH batteries. It is recommended to charge the battery in an environment ranging from 0℃ to 40℃. At the same time, the surface temperature of the battery should be regularly checked.

Can NiMH batteries be trickle charged?

As NiMH batteries are intolerant to overcharge, trickle charging tem has to be undertaken with care. While NiCd batteries may be trickle charged at a rate of around 0.1C, this is considered too high for NiMH batteries and it is generally accepted that for most NiMH batteries trickle charging should be accomplished at a rate of about 0.05C.
