Hi Art_in_FL

Rechargeable Alkalines might be the way to go for long storage life combined with moderate drain intermitant use such as in radios, remote controls, GPS devices etc. If long storage life is important then the new rechargeable Alkalines have similar characteristics as normal single use Alkalines. For higher drain use such as flashlights and cameras etc then the Eneloop, Infinium NiMh are excellent, having a storage life greater than 12 months losing only 20% of the initial charge.
