RCA Model 25110 - Need new battery for headset

That type of spare is not normally available on phone sets. I guess you could contact Panasonic.

Hi, a simple way to determine if the problem is in your headset or in your phone itself is to try the headset on another telephone. If you do not have another headset compatable telephone, you can try taking the headset to a local radio shack (or other electronics store) and see if they will test it on another phone for you.

Are you sure the model isn't Model 2-9910A? In any case check out, www.radioshack.com or www.batteriesplus.com. They will surely have it.

I could not find the battery for your phone. But you may click this link and I hope this would help you:

I believe that any battery that has the same voltage output and same connector would work with your phone.

Mine was doing the same and I just pressed the "find" button on the wall plug in thing- and the headset started working....you may want to try that.....?????

I suggest you read the manual. If you don't have it, search for it and download it

I, too, have this model phone and love it. The headset battery barely lasted 9 months. I've been bumped around to many places including Thompson, Radio Shack, etc. I do believe Thompson (800-338-0376) has the battery for the HANDset, but they DO NOT have the battery for the headset. The HEADset battery is available through partstore.com (on the internet) (866-925-7278). This shipping document gives you the pricing info:

RCA BATTERY/ LI-POL 52707 $20.99 1 $20.99 Sub Total: $20.99 Shipping/Handling: $7.95 Tax: $1.26 GRAND TOTAL: $30.20

You may well find that the HANDset battery is available there, also. The RCA HANDset battery part number is 5-2683. You will need this to cross reference if you use partstore.com.
Warning: Radio Shack will say that they have the replacement battery. I had to send the one they ordered for me back to Radio Shack - - don't need to say more!!!

Hope this helps.

I guess one of the two phones may have opened the locked-extension phone function!
