4-Pack BK-40AAABU 1.2V 400mAh Replacement Battery Pack for Panasonic Cordless Phone Handset BK40AAABU

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.

My batteries were getting low on my cordless phone. I thought I could just use regular batteries but they didn't work. So I bought these and now my cordless phone is working perfect.

Good quality!

Great quality, fit my cordless phone and instantly brought it back to life. 2nd purchase, third life for the cordless phone. Long Lasting!!

These Panasonic cordless phone batteries work great and just as I expected. I made a wise choice among many batteries offered via Amazon. My phones are all cordless Panasonic; so, no problems existed.
