How long will NiMH batteries hold their charge?
Official responses vary, but in my experience, I usually see a bit under 1% per day. So after a few months of sitting idle, expect your NiMH batteries to be down at about half of their capacity. Either way, Maha recommends recharging your batteries at least once a month even if you don’t use them at all. NOT using/charging your batteries much is definitely worse for them then using them a lot! Use and charge them regularly and you should get at least 2-3 years of solid service from them, after which time it’ll be worthwhile investing in newer and higher capacity batteries anyway. And if you need batteries that hold their charge longer and don’t use as much power anyway (flashlights, alarms, TV remotes, etc.), then go for the Imedion batteries since they’ll hold most of their charge for a year or more.
