Review on 🔋 Kastar Battery Replacement for Panasonic Cordless Phone: N4HKGMA00001, P-P511, HHR-P511, Type 24 Rechargeable Battery by Ryan Frawley

I bought three of these batteries for my Panasonic cordless phones. I installed two in phones immediately upon receipt, tk. old batteries didn't hold a charge. They worked great. The price I paid for three batteries was the same price I paid for one battery at my local retail store. Battery Upgrade: These batteries have a fatal flaw. They don't have the option to stop charging once they're fully charged. If you leave the phone charged like I have done with Panasonic batteries. You will clearly overcharge and the battery will fail. You must remove the phone from the charger once the battery is fully charged. I found that I could buy a brand new Panasonic wireless system for the same price I would pay for three new replacement batteries for old phones.
