Perfect replacement for my Panasonic cordless phone
I bought this 4-pack to replace the old worn-out batteries in my Panasonic cordless handsets. Installation was straightforward—just pop them in like regular AAA batteries. Once installed, the phones immediately powered up and started charging without any issues. Performance has been solid so far. The phones hold a charge well, and standby/talk time feels just like when the phones were new. It’s great that these are rechargeable Ni-MH batteries, so I don’t have to worry about frequent replacements. Having four in the pack also gives me backups ready to go. The price is very reasonable compared to OEM replacements, and the quality feels just as good. I appreciate that they fit perfectly and didn’t require any modifications or adapters. Overall, if your Panasonic cordless phone is struggling to hold a charge, these batteries are a simple, cost-effective fix. Highly recommended.

OK, but didn't last so long. expensive.
They worked. But I don't know if they have a short life as the phones are not working so well. I don't know if it is the fault of the batteries or not. Maybe they have to be replaced again. They are very expensive.
