Rechargeable battery question

aliasojo

One of my house phones needs new batteries. The present ones came with the phone and are Panasonic AAA size. It says on the battery 1.2v Min 550mAh so does that mean I can use absolutely anything above this? Duracell have ones that are 1000mAh but it doesn't state the voltage.

Someone told me the newer rechargeables need intelligent chargers so maybe those are no use for my phones and I should just get bog standard 550mAh again?

You need to use the same voltage, but you can use a higher mAh rating if you want.

All rechargeable AAA size batteries are going to be 1.2v. You maybe need to check what type (NiCad NiMH) were supplied and check the manual to see if either can be used. There are small detail diffences in how the two types should be charged but many chargers can handle both.

The one's that came out of the phone were Ni-MH.

Most house phones live on a charger cradle so standby time isn't an issue, and any rating battery if healthy will power a phone for far longer than any normal human can talk! (unlike mobile phones, cordless house phones only need tiny transmitter power)

Upgrading to anything expensive is pointless, pop into Aldi, they always have cheap decent quality NiMh batteries on the checkouts.

I found on my BT DECT phone that if I put in too high a mAh rating, it didn't like them.
