Kastar Rechargeable Shaver Battery Pack AA 1.2V 2000mAh Fits Braun, Norelco, Remington Shaver Models and Others (deatil Compatible Models Please Search The Below Description)

Replaced dead battery in my old Philips Norelco 7310XL. Runs like new again. Requires soldering iron and skills to remove old battery and install this new one. Fit perfect. Holds charge just fine and runs great so far. Even the shaver ' Charging ' light still works

Took the old one out, soldered the new one, and it gives 9 shaves on my first charge. Easy install, perfect fit, great charge.

For my Norelco shaver, I had to carefully trim the solder tabs a bit narrower to easily slide into the solder holes on the circuit board. You need both de-solder and solder skills to install. Once installed charged up and works well.

I have an older Braun 5416 shaver which gave me very good shaves, unfortunately it basically stopped working because the original battery would not hold a charge even when plugged in, making the shaver almost useless. With this battery and some instructions from a YouTube video, I as able to replace the original battery - side note, it is NOT an easy swap - and breathed new life into a shaver that I thought would never be used again. Some users have claimed that this does not hold a charge well, but I find that it does hold a charge well.

The product fit my Norelco shaver just fine except for the tabs. Had to snip the tabs a little thinner. I was able to solder it in without issue. Luckily, it took a charge. My first run lasted about 20 seconds. Since then, I have been able to make it last for about 1 minute at full charge... roughly 30 seconds before it slows down noticeably. This is why I don't believe it is 2000 mAH, at least mine is not. There are no directions included to tell you how to condition the battery, so I'm fully charging and discharging each time. Luckily, my shaver works while plugged in too. I now have a corded shaver that works for a few moments unplugged. It is too late to return it, especially since I modified the tabs. Good luck if you buy one. UPDATE: Within a few weeks of my earlier review, the battery charge reduced to about 10 seconds on a full charge. It still works when plugged in.

Despite the product description saying it works on the Norelco 7310xl, mine clearly has the 3.7 Li-ion installed. Check your battery voltage. 1.2v is NiMH (or other).

The battery arrived on-time, is as described and in new condition. My 10+ yr. old Wahl 9627 cordless trimmer had stopped holding a charge for some time. So, I was only able use the unit with the power cord attached and plugged-in - which was a little inconvenient. I was able to disassemble the unit pretty easily (pop off the blade set, remove the 2 screws and then separate the 2 case halves) to access the 1.2V NiMH internal battery. The replacement was just a matter of desoldering the old battery and then resoldering the new battery on to the mini circuit board. Very easy to do and it only took a few minutes to do and then reassemble the trimmer. This Kastar 2000mAh battery has more than twice the life of the original 800mAh battery -meaning each charge will now last about twice as long as the original battery! NICE!! The trimmer now works like new and I am absolutely delighted! Thank you!

The battery seems to work, but the two leads (connections) are so thin and weak. Much MUCH cheaper than the battery it replaced from Philips Norelco. Almost broke when installing (it's like tin foil). I would have paid an extra $1us for the connections to be thicker and stronger so they don't break easily (like what came with the razor 10+ years ago). If the connections break over time, I'll come back and edit this review to 1 star. For now, 2 stars if it survives. The Chinese need to learn we are willing to pay a little extra for better quality, not the cheap Chinese crap being made today. Build stuff to last 10+ years, not to break in 30 days! Stop being wasteful.

Impossible d'avoir plus de 1450 mAh après 5 cycles de recharge avec un chargeur intelligent. :-(
