RocketBus 2 BK-40AAABU Replacement 1.2V 400mAh Battery Packs for Panasonic Cordless Phone Handset

The original batteries failed to hold a charge and I replaced them with a set of Panasonic NiMH batteries which sometimes did hold a charge and sometimes did not. My conclusion is that not all NiMH batteries are the same. Thus, it is important to make sure that the replacement batteries have the same model number as the original batteries.

you only need rechargeable batteries. But it was cheaper for me to buy the replacement post cap which included a battery.

Two batteries were not able to charge on the phones.

Bought these AA rechargeable batteries to replace some of my older solar landscaping lights I had in my yard. A lot more affordable then buying from the local Walmart store. Seem to work so far so good. Thanks

I was so happy to finally find batteries that worked in my older Panasonic phone. I ordered four packs of two, and only two of those batteries worked. Sadly, due to some health issues, I wasn’t able to return these in time, so I’m stuck with very expensive batteries that don’t work! Very disappointing!

When my landline phone "died," I wanted a quick and dedicated battery replacement. Amazon made this easy and at a reasonable price. My main phone was functioning again the next day! I have not had the batteries long enough to judge their longevity.

This battery is not available in coastal SC, so it has been a pleasure to have found it on Amazon. Having installed these batteries several weeks ago, they will last much longer than then Energizer batteries that we have now given up!

Batteries are batteries some work well and some don’t depending how you use them

Received when promised. Packaged well. Worked as expected. Five stars

Hasta ahora todo bien, mantienen buena carga

Son igual que las pilas originales de los teléfonos, funcionan muy bien.

This was required for my mobile phone.

I need 2 buy 3 more. They work quite well
