2 BK-40AAABU 1.2V 400mAh Battery Packs for Panasonic BK40AAABU Highpower Corun Cordless Phone

Did the job! Panasonic phone works again! YAY!

I have no reason to believe that these batteries are not good. I purchased for my landline phone as it stopped working and I presumed it was the batteries. These new batteries, exactly what was in the phone originally, did not correct the issue. Simply because the phone is dead after 9 years. Just bought a new landline phone onAmazon.

I bought this for my gramma’s home phone because I literally couldn’t find any phone batteries in stores anymore without going to an out of the way to a battery store. I hesitated to buy this because the old battery in hers were connected together but this worked perfectly.

Difficult to insert.

THE BATTERY: THE HEARTBEAT OF IT ALL ... THE HEADING SAYS IT ALL BUT I WIALL ADD THAT THEY WERE WRAPPED 2 PER PACK = 3 WONDERFULLY IN BUBBLE WRAP THEN IN THEIR GRAY SELF STICK MINI PACKAGE SLIPS THEN ALL 3 PLACED IN THE AMAZON BROWN TEAR AWAY.. WONDERFUL ARIVAL AND THEY WORK.

phone batteries great product

Exactly what we needed. A little pricey, but free shipping made them worthwhile.

We have tried buying battery locally for our cordless phones but none seem to last very long. These battery are of good quality, they work for long periods of time. Very pleased with the product.
