Review on HHR-P104A Panasonic Cordless Phone Battery by Lisa Becker

I have two Panasonic KX TG 5632 mobile phones which I use for my business calls. My calls usually last about an hour and it's cumbersome to change handset/headset during a call. So I want a battery that will hold a charge. The last time I had to replace these batteries was about 10 years ago. The ancients began to lose their ability to hold a charge. The Panasonic HHR-P104A are specially designed for my phone and have a pretty long lifespan. They might cost a few bucks more considering the battery life, but they're probably a better deal. I believe the cost is around $1 a year. I charge when the battery is down to 1/3 and typically get around 8 hours or more of talk time on each charge. I don't leave the handset in the charging cradle because I find that constant charging reduces battery life. I am very satisfied with Panasonic batteries.
