Kastar 1-Pack 2.4V 1000mAh Ni-MH Battery Replacement for Razor/Shaver Battery Philip Norelco BodyGroom 7100, Philip Norelco BG2040/34, Philip Norelco TT2040/32, Philip Norelco PG350, Remington PG350

I have been keeping my water pink wp900 alive for about 10y more than it's life span by replacing batteries and parts as needed. I've bought many batteries for this unit but this last set from about 1.5y so are by far the most powerful and long lasting of the seemingly similar versions I also bought off Amazon. They are notably more powerful than the OEM batteries and longer lasting... Still 100 percent as strong as they were when new... Amazing. At this rate, I can keep my wp900 for another 10y... Rather than succumb to water picks planned obselescence ... Where the battery dies and you need to replace the entire machine...Note to replace the batteries you have to take apart the toothbrush and solder in the replacements... So it's not a plug and play setup.Excellent value.

Just as original batteries, they only lasted 2 - 3 years in my Norelco shaver, then I have to replace them again, probably due to Ni-MH technology. I only found this vendor who sells them cheap, therefore there is nothing to compare. Pins are reversed. You have to be able to solder to it to fix pinout. But it's cheap and if you can solder this is the way to go. The only bad thing IMO is every time I have to open shaver I brake one or 2 little plastic tabs that hold internal covers together.

I bought these to replace batteries in a couple of Norelco BG2030 trimmers that would no longer take a charge. With my particular shavers the polarity of the new batteries would be reversed if I pushed the pre-soldered tabs through the little holes in the battery compartment. So I flipped the pack upside down and just soldered the wires to the correct battery posts. It's too bad Norelco doesn't make battery replacement easier since most people don't do soldering. However, thanks to a useful video I found on YouTube I managed to fix my shavers with minimal effort and save a lot of money by not having to by something brand new. I'm leaving the battery life rating in his review blank since it's too soon to know how they will actually hold up.

Works!

The battery connection leads didn’t work with my NORELCO series 2000 shaver. The +/- leads were opposite from the factory installed battery.

The pins were backwards/reversed and it held a partial charge once and now wont recharge at all. I would like a refund

Installed and working. Tks.
