🔋 Kastar Cordless Phone Battery Replacement: Compatible with Panasonic KX-TG2740, KX-TG2750, KX-TG2770 & P-P511 Type 24 Review

Arrived early and in good condition. I have used them several times. After the first charge, they last for a few years. For the price this is a good deal.

The battery is not Panasonic but works very well. Required for an old fax machine. I now consider the fax machine to be an antique.

I still have cordless home phones and one of them has an empty battery. I bought the battery from Interstate Battery and it never held a charge. I decided to check out Revain, found your company and ordered a battery! That works great!

This is the correct battery for Panasonic phones that were originally fitted with a NiCd battery. DO NOT use chemical nickel-metal hydride batteries: The charging circuitry in Panasonic portable phones "frys" nickel-metal hydride batteries and they last less than a year. Only use a NiMH battery if the mobile phone was originally equipped with a NiMH battery.

The batteries on our two forever portable phones ran out FAST - they ran out twice during recent calls to my parents causing them to start a cycle of attempts to call me ( the battery was dead) , I tried to find my cell phone and called them (but of course their line was busy because they were still trying to reach me). I'm very glad I received these replacement batteries quickly, charged them overnight, and had follow-up calls with my folks with no hiccups or worries!
