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.

Got these to replace the batteries in my WaterPik WP-450. I chose these for the 2000mAh per battery, price, and the fact I couldn't find a cost effective battery pack for the WaterPik with the positive+ and negative- terminals positioned in the correct orientation. They fit perfect but they are not plug and play. It took some de-soldering to remove the old batteries and soldering these to make them work. I had to make my own battery pack with two of the batteries, tape them together and do some soldering, but it all worked. The WaterPik regained its power and they are working great so far. I'll know how long they last overall and per charge over time, so I can't answer that in this post. I could easily afford a new WaterPik but if I can economically fix something I'll give it a try. If these batteries fail no big deal, they were cheap and they are doing the job now.

Just what I needed. Replaced batteries in Remington shaver in an upgrade. Works great.

Great battery life. Easy to use & easy to charge! Definitely recommend!!

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.

These batteries have weld tabs, not solder tabs. The tabs are not tinned, and they do not take solder.

Used these to fully rebuild a battery back for my old Newton eMate 300. Not an easy task, but the result was perfect and more than doubled the run time. No complaints. Welded soldered tabs made construction fairly straighforward. They are just a hair slighly larger in diameter than the old batteries, but still easily fit the plastic pack without a problem.

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