Panasonic cordless telephone - battery problem?

Hi there!

I was hoping that someone could help me with a problem I'm having.

2 years ago I purchased a Panasonic KX-TG2650CN cordless telephone for my father. He decided not to start using it until last week when his old cordless finally died. The battery was already installed in the handset, so it had been in there for at least 2 years (if not longer).

He allowed the unit to charge 8 hours, and when the green light came on (indicating complete charge), he took it off the handset, and made a phone call. When he was done, the handset shut off as if there was no power. He then charged it again, and the same thing occured.

The interesting thing is that it doesn't matter whether the phone call is 5 minutes or 4 hours; as soon as he makes one call and hangs up, the phone dies.

He went out and purchased a replacement Panasonic battery (indentical model #) and he is still having the same problem.

I was wondering; what could be the problem? Has this phone always been defective, or was it caused by the fact that the battery was left installed for so many years?

Any advice would be greatly appreciated. Thanks in advance! Scoobadivr

That's my guess.

As long as it wasn't ever charged it should have been fine. Try charging it for 24 hours before using it again.

These phones have a big battery/charging problem. We have three at or shop, charge them for fifteen hours, & run them till they run right down, otherwise they won't last very long at all!! have a look here at the reviews. You can "very carefully" put a load accross the battery pack, to "run it down", then charge it for fifteen hours, but you must let it run right down. Rono.

How do I do put a load across the battery to run it down?

let

If you don't know, don't try.

Bullhockie!

Simply unplug the phone from the telephone jack and turn it on. Leave it that way until the light goes out, then recharge. You might want to repeat this a couple of times...or you might want to simply get a new battery and try that. They're not 'that' expensive.

repeat

Balderdash! That isn't "very carefully putting a load across the battery pack".

it

and

Just 'how' carefully must one put a load across the battery? The original advice was to not do it at all, unless one had some arcane technical know-how, implying that it was dangerous. I merely pointed out that it was not all that difficult, and not dangerous at all, if done as outlined.

Someone *emailed* me to say that it might not be possible to do as I detailed. To that person: I've not seen a phone which will hang up on its own, as postulated. Perhaps there are some out there. In any case, please limit your replies to this forum. It's bad form to email a reply.
