Review on 🔋 Pack of 4 Panasonic HHR-75AAA/B-4 Ni-MH Rechargeable Batteries for Cordless Phones, 700 mAh by Daniel Beaver

So let's start with my cordless phone. This is Panasonic KX-TGA641. If I look for that number, these are the most recommended batteries. But the batteries in this phone are HHR-65BU. When I use this to search, my phone model is never listed. I only needed four so that was a consideration too. After reading some reviews and Q&A on size, voltage and amperage I got them. They were a little cheaper than the '65s and sounded like they would work. Good. Yes they do power the phone but for some reason they keep showing "using batteries" on the display instead of the date, time and "missed call". etc. Well, these are rechargeable batteries. There are even Panasonic batteries. But for some reason they are not recognized by the phone. The phone does not light up when removed from the holder. It doesn't show if there is a missed call or B. a new message etc. It rings, a message is received, a call is made etc. The phone "works" but I wouldn't say it "works" is working". I returned them and got 4 of these that match the old batteries although they cost a little more per battery. They seem to be working fine. As expected (see separate review), I can't imagine other brands of batteries working if a larger capacity Panasonic battery doesn't fit. Maybe this is just my special model, but buyers beware.
