Letter Re: Shelf Life of NiMH Batteries?

JWR,
There have been a few posts about batteries lately and a question I have been unable to find an answer to is:

Do Nickel Metal Hydride (NiMH) batteries have a limited storage life before they are put into service (receive their first electric charge)? It would be nice to know if I can buy a quantity and store them away until needed. I’ve not seen this addressed anywhere and maybe you know or one of your readers knows the answer. Regards, – Keith

JWR Replies: That goes beyond my base of knowledge.  Would any readers care to chime in on this one?
