Default Charge Shelf Life

How long will a NIMH hold a charge if it is not in use?

Default RE: Charge Shelf Life

Here's some useful info: http://www.rcbatteryclinic.com/

NiMh packs have a higher self-discharge rate (~3-4%/day) than NiCd (~1%/day). Apparently LiPolys have a VERY much lower rate and can be charged up days/weeks before use and still be "full" when needed.

Cheers, Phil
