I have four Panasonic phones with this dreadful battery. Everyone has been replaced at least once and two of these have failed again. But no more!

There is good news and it doesn't require you to build your own battery. I bought the Energizer replacement P511 battery which is has much better amperage (1200mA vs. the Panasonic's 850mA) and uses better battery technology (NiMH vs. NiCad, and NiCad is notorious for memory effect problems).

I will post a review of the Energizer on its page, but a quick result is that I now have two phones using the Energizer and both work longer on a charge. And a surprising difference is that the phone seems to work better at longer distances from the base! Not sure why (perhaps the extra amperage??) but where I always have had some static using the same phone in the same room, I now have clear reception!

I had been considering ditching these phones altogether, but maybe the new Energizer batteries will forestall...Read more

1.0 out of 5 stars OEM NiCad, only 850 mAH battery, just dreadful, October 10, 2005

This is just an awful battery. It came as the OEM battery on my Panasonic KX-TG2267 phone. The P-P511 appears to have been used to power a host of other Panasonic cordless phones as well.

The battery quickly stopped holding a charge.

I looked for alternatives, and got an Eveready ER-P511 NiMH battery, which at 1200 mAH, is a slight improvement. But hey, most NiMH AA batteries are way better than that these days!

So I decided to make my own battery, out of some 2500 mAH Eveready Energizer NiMH AA batteries. It's not that hard. Here's how you do it:

First of all, save the original P-P511 battery that came with your phone. Study it. The P-P511 battery is essentially made of three AA batteries linked together in series. Linking batteries in series just requires that the minus pole of one battery contact the positive pole of the next battery, and so on. These links can be made by using wires or strips of metal.

Don't buy this, I bought it and it died within 12-18 months just like the factory Ni-Cad. Buy the new Ni-MH replacement HHR-P402 it has now lasted me 2 years at least. I didn't have the Ni-MH option when I bought this so I guess I can't fault them for selling it but now the Ni-MH option is here so don't buy this.
