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)

At this stage, I'm giving this battery a five stars. This will be the second time I've replaced the battery in my shaver, the previous battery lasting years and years. Yes the battery comes with tabs that are easily pulled off and the rest was an easy fix. The installation is straight forward although the positive and negative contacts have to be soldered on.The fix and battery is much more cost effective that buying a new one.

Met all expectations. After first full charge lasted over six months on my razor before needing another 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.

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 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).

Soldered in as replacement on my Norelco G370 Trimmer. Trimmer works so good now I might just go Bezos everywhere!

After figuring out how to get into the battery compartment, I bought two of these for my 20+ year old Remington razor. The used ones were easily removed. I soldered the negative tabs together of the new batteries and soldered each positive tab to the respective terminal. After assembling the unit, I charged the razor overnight. It's been several weeks now and I get five shaves before recharging. The old batteries only lasted one shave. The amp/hour rating is slightly larger than the old batteries, so I expect to be using this razor for the foreseeable future.
