Tenergy AA 1.2V NiMH 2000mAh Flat Top Rechargeable AA Batteries with Tabs, 4 Pack

Worked well for replacing the batteries in an older Norelco 965RX shaver. Charged fast and have held for way longer that the 500mV that were stock size.

My old shaver was headed for the junk drawer until these batteries gave it new life. The flat tops with solder tabs made installation straightforward — no awkward hacks or loose connections. At 2000 mAh, they hold plenty of charge, so I’m not stuck recharging every other day. The pack of four means I’ve got spares for future repairs or other gadgets. They’re solid, reliable, and way cheaper than buying a new shaver. If you’re handy with a soldering iron, this is a quick win that saves money and keeps your gear running.

These batteries were the perfect replacements for my Laube Speed Feed cordless trimmer! A little bit of soldering, and my clippers work like new again! ❤️ Save some money!

I needed to replace 4 batteries in an OEM instrument which originally had tabs welded to their ends that had wire leads so they would easily fit through a hole in the printed circuit board. I was unable to locate replacement batteries with that configuration so settled on these that have flat tabs at the ends. I ended up soldering a wire to the PC board running through the hole, then soldering the wire to the tabs. The longevity of these is great and they charge up very fast.

I am writing this review 24hrs after installing one of the batteries in an Oral-B Vitality toothbrush. I didn't do the install right after receiving the batteries. It was a few months after so after it was installed, the battery needed a full charge (24hrs). I did have to trim the battery leads to fit though the brush PCB. Scissor can do the job. The battery was a little longer than the original battery but it's length didn't prevent it from being able to be put back together. This was my first time I had swapped out a soldered on battery. I used cooper braid for the desoldering. I suggest using a bit of flux on the braid. I didn't remove the charging coil like suggested in one of the videos I watched. It took me about 20 minutes from start to finish. Be patience when removing the PCB. I will have to find a use for the other 3 batteries. I will try to update status after a month or so. I have used the toothbrush and it seems as good as new.

I bought these to replace the batteries in my electric shaver whose old batteries were losing capacity with age. After the replacement, my shaver works fine. I had two cells left over and when I told my son about this, he told me he had a practically dead rechargeable shaver. I "re-batteryed" his shaver like mine and now it works too. Since all this is recent, durability is unknown but should be good, as with other such batteries.

They work fine, but only lasted 7 months, so cycle life is not great. I would estimate about 200 cycles. Should be 1000 cycles minimum.

Perfecto gracias

exactly as described and the tabs work well for simple soldering.
