I have 3 old Whites C cell packs 4.8 v. and was updating too NiMH Battery..Had some old ones at the house .but turned out to be junk . Had the hole pack together and they only lasted about 3 hr's.Does anyone know of a good place online or a store that would have some.C. or sub C somewhere around 2500 mAH give or take. Cant seem to find a good name brand.or I don't know what a good brand is anymore. LOL.I see lots online .But not sure which to get.
