Cordless phone dying. Replacing battery this simple?

[JEDI]

Ativa 5.8ghz encrypted cordless phone.
i've had it for 5+ yrs.
now the handset only lasts for 5min talk.

battery looks similar to this:

Looks like regular AA rechargables.
on the phone, it says 2.4v 1500mAh nimh.

is it as simple as popping out the battery from the cradle and putting in new nimh ones?

yup

they might be soldered. or glued. You can find replacement packs.

 

[JEDI]

yup

so if the new battery says 1.2v 2000mAh, then my handset will have 2.4v 4000mAh?

Yup. The voltage and amperage isn't etched in stone either. You have some leeway choosing batteries. Amperage totally doesn't matter except for battery life. I'm not sure how much room you'd have for the voltage, but I wouldn't be bothered using 1.5V cells.

rechargeable are all 1.2v instead of 1.5v. There are some oddity such as rechargeable alkaline that is actually 1.5v.

I thought I remembered some variance, but I might be mis-remembering. I've used all the popular rechargables, and I might be confusing them.

Not quite. Using two 1.2 V 2000 mAh batteries in series in the holder will get you a 2.4 V battery pack as needed, but total power will still be 2000 mAh. Remember that they MUST be of the NiMH type (same as originals) so they can power the phone and, MOST importantly, be properly charged by your existing charging system. However, they do NOT need to have the same mAh rating. Only the battery type, voltage and physical size need to match.

Just buy a new battery pack for it. Why try to create one? Is it super expensive?

the last cordless phone set I got for mom had all AAA's, NiMH.

So far havent died but when they do it will be easy to fix.

i have spare AA nimh sitting around.
bought the Costco enlope AA superpack last year.

hm.. the batteries aren't soldered but they're not coming off the cradle either
glued in???


edit:
yup, batteries glued onto the cradle.
wrecked the plastic cradle taking it apart.
used scotch tape to put things back together.

works. have dial tone!
now will charge overnite and see how long it lasts tomorrow.

Hot melt glue, probably.
