NI-MH AAA Rechargeable Battery 1.2V 550mah 4-Pack AAA rechargeable Batteries for Panasonic BT Gigaset Cordless Phones

Really good value. One of our 4-set Panasonic phones - in our bedroom - kept 'beeping' throughout the day and night! We didn't have a clue why, and eventually, come bedtime, I just took it off it's carriage! However, that's when one of those eureka moments happened... I realised the two re-chargeable batteries in the handset might have died completely.So I bought this 4-pack rechargeable batteries, and as soon as I'd inserted them, the phone worked perfectly, and continues to do so.

Work well

Seems to be working well

Battery printed numbers made it easy to find the correct ones for our old BT phones. nicely made no sharp edges, easy to install, enough charge to work straight away and didn't take long to get to full charge. good value much cheaper than having to buy new phones.

Just what I needed to replace the battery in the main line phone

When these batteries arrived we found they were actually Panasonic brand. They appear to work much better in our cordless phone handsets than the previous Duracell items which got hot and didn’t retain any their charge. So all in all very happy!

Fitted and charged OK

It took several hours to fully charge the batteries, then when fitted in the phone it didn't work. The problem was that the contact stud on the positive end of these Panasonic batteries was shorter than the original equipment batteries and wouldn't make contact with the terminals in the phone. I adapted the phone contacts so it would work and it seems okay now. Too early to comment on performance because only got the batteries today.
