I replaced these in my Panasonic phone my old ones lasted a long time but maybe having the phone in my garage killed the old ones. I can leave these off of charging for over 2 weeks and they still have a charge

I need new batteries for my PANASONIC landline phone. It hand been used since my mom passed. I decided I wanted to restart my my phone for a back up. Batteries charged up very quickly. Now I have the back up that I needed. Hope I can get all the out. In my be sitting! Good battery for the price

The problem is I've been trying to get rid of my home phone (s) for years. Finally the batteries were shot and I told my wife that if the battery replacement didn't work I'm getting rid of these things. Well they worked and now I'm stuck with Medicare calls and car warranty calls for the next few years. Thanks a lot for making these stupid batteries last so long!

My portable phones were cutting out and calls were dropping. Replaced the batteries with these no more problems

Why do manufacturers have to make EVERYTHING — even buying replacement batteries — so frigging difficult, and then compound the problem by writing unintelligble descriptions that would confuse the person who *invented* the cordless phone?!After spending far too much time trying to figure out the correct replacement batteries for my 12-year-old Panasonic cordless phone handsets (base station model KX-TG6581 or KX-TG6583T, depending on which label on the phone you believe), I ordered these batteries because they were the least expensive ($10.90 for 4) rechargeable batteries which appeared to match the exact specs of the original Panasonic batteries (which lasted 10+ years). The replacement batteries came professionally wrapped (see photo), not just rattling around in a plastic bag.Both handsets detected the batteries immediately, and after 6-8 hours of charging, the batteries now register as fully charged. The “Use Rechargeable Batteries” message is finally gone from both handsets and they are now working normally for the first time since the original batteries started dying.I’ve posted pics of the original batteries and these replacements. On the surface, they appear identical to the OEM batteries (except for a slight color difference) and the replacements say “Panasonic.” Do I think they are genuine Panasonic batteries? I wouldn’t put money on it. The wording on the batteries is identical, but the typeface is a little different and the new batteries say “Panasonic corporation” (small “c” in corporation), which is one typo I doubt the real Panasonic Corporation would make.Whether these batteries are genuine Panasonic or good look-alikes, they charged as promised and the phones work. That’s all I wanted. If they spontaneously combust or die prematurely, I’ll update this review, but for the moment, they appear to be working as promised and are the best deal I could find on Amazon for this type of battery.5 stars.

Muy buenas y co paro les con teléfonos inalambricos

I bought these to use in my Panasonic landline phones. I thought I would have to replace the phones but these batteries gave them all a new lease on life. I have used them for several months and have been very happy with them.

Easy to find, good price

I’m great batteries for the phone, now like new. Charge last a long time again.

As Described

Was to replace the battery in a wireless phone that was old and no longer holding a charge. Calls kept dropping out. This worked and solved our problem.

Excellent batteries for a great price.
