What is the shelf life of a NiMH battery?
3-5 years
The life cycle for NiMH batteries is approximately 700-1,000 charges. Because they have a high energy density, nickel metal hydride batteries don’t deplete as quickly. As a result, they have a shelf life of 3-5 years.
Do NiMH batteries go bad?
Standard NiMH AAs will deteriorate with disuse. They will lose their charge and then hold less power as a result over time.
What should you never do with NiMH batteries?
1 Never mix batteries from different manufacturers 2 Never mix batteries of different capacities 3 Never mix batteries of different chemistries, i.e. NiCd, NiMH, Lithium, etc. 4 Never DROP the battery if you can help it as NiMH batteries damage internally quite easily 5 Never store NiMH in the refrigerator 6 Never expose to extreme heat
Are there states that do not recycle NiMH batteries?
Because of this, many states have banned NiMH batteries from landfills, include Minnesota, New York, New Hampshire and Florida. To see if your state is on the list, visit the Call2Recycle website. But even if your state does not require NiMH battery recycling, it is a good idea to keep them out of the waste stream.
What should the trickle charge rate be for NiMH batteries?
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.
Can a NIMH Charger charge a Ni Cd battery?
Caution: Both Ni-Cd and Ni-MH batteries present a user hazard if they are fast charged for an excessive length of time (subjected to abusive overcharge). When the battery reaches full charge, the energy being supplied to the battery is no longer being consumed in the charge reaction, and must be dissipated as heat within the cell.
