We have Panasonic cordless phones which came with Panasonic AAA batts, capacity 750 whatevers. They've been getting weaker & I just replaced with Uniross, capacity 1000 whatevers.
When charging the phones have a light that starts out red & turns green when they're done, but these just went on and on charging and never turned green; so I want to know, is this harmful for the batteries/charger/environment? Should I get new ones of 750 again? (I can probably use the 1000 ones in TV remotes or something)
