cordless phone batteries

[Red Squirrel]

One of our cordless phones keeps dying, so the battery is probably finished. It's a battery pack that looks like 3 AA batteries and has a wire with a small plug. They are ni-cad batteries. Could I just take regular AA's and hook them up to create a similar battery pack? Would it work ok?

Worse comes to worse we'll get a new phone, but if a simple fix like that would work, then why not. I figure, as long as I buy nicad batteries I should be fine. They're usually 1.2 volts. The only thing I can think of is that the mah rating may be different. So if the phone charger overcharges them it might kill them faster, could this be the case?

Try it and report back.

i wouldn't put the phone in the charger with those regular AAs in there... or did you mean individual rechargeable cells?

or just look up the model number on the battery pack or the model number of the phone system and look for batteries for it.

You can buy nicd aaa batts from various places but you aren't supposed to solder directly to the cells as it can cause damage or risk of explosion. They sell various sell types with 'tabs' that you can solder if needed.

If you use the right cells you could repair your own pack, but, you can't substitute NiMH or Lithium or Alkaline, etc as they won't charge correctly.

that was the only concern, was not sure how I'd hook them up, so solder is a bad idea?

And yeah I'd get batteries that are the same type. I'll check for an actual battery pack replacement first, but probably have to order that, and it's probably just as expensive as a new phone. If there's a small chance of ruining he phone, I'll take that chance, but if it can explode, maybe not. 😛

I've gotten some good deals on those type of battery packs on eBay in the past.

They sell cordless phone batteries all over the place and they aren't that expensive.
