4PCS NI-MH AAA Rechargeable Battery, 1.2V 550mAh Battery for Panasonic Cordless Phone, HHR-55AAABU Replacement Battery

These batteries worked well. Saved me from having to buy new phones

We couldn't find replacement batters for our ATT cordless home phones- but found them easily on Amazon. I ordered a box of 4 (2 per handset) because only two phones were dead. However. They came so quickly, were reasonably priced so I ordered four more, as a precaution. I am handicapped and Amazon is an amazing resource for me. Thanks Amazon and all you very nice delivery people.

These batteries do last forever thankfully. The price was very reasonable for 4 batteries and they are so easy to install. I have found that using the exact Panasonic battery they recommend will work best for a Panasonic phone over batteries that will work for a Panasonic phone. They last longer and work better.

Worked fine to replace answering mach8ne headset batteries

So far; so good.

These are needed for my in house phones. Older batteries died after many years of use. The new ones fit perfect and charged with no issues. Great prices

I wondered whether this would be smoke and mirrors, but they appear to be the real deal and definitely works well. My batteries were 10 years old and last only 30 minutes of talk. This is much better!

Returned product. Was not what I needed as they were wrapped as one large battery. I needed them for two telephones.
