I have a backup battery for my airsoft gun, it is a lower voltage (smaller) but higher amperage (nimh vs nicad). Will using the charger damage it? it’s a 200ma charger and a 400mah battery, so I should theoretically charge it for about 3 hours but should I change that because of the voltage?

Bill asked:


I want to buy an electric shaver and trimmer (2 in 1) that can be used directly even if the battery is not charged because its really annoying when you are getting late and your shaver refuses to work midway because of poor battery backup. Unfortunately most of the shavers I have come across only work after charging :(
So I need suggestions where to find a 2 in 1 shaver and trimmer that works without charging ?

I know when a new battery is needed so I’m looking for other answers. My FIREX 12000 series CO/Fire detector beeps only a month after replacing the battery(beeps once every 60 seconds). Sometimes it seems to take a break from beeping. It is 1 in a connected series of 7 in the entire house - AC with battery backup. It is the one closest to the kitchen.
