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

Works great! Very powerful.

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.

As advertised

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 used these to repair a battery pack for my Andis clippers for 1/10 the price of the new pack. The pre welded tabs made soldering the cells in very easy. The battery works perfectly now and lasts longer than when it was new.

Works great

Needed for my Braun shaver only two required squeeze the leads to make them half wide, read the YouTube instructions for disassembly, desolder the leads make sure you mark with a sharpie negative and positive before you remove the batteries on the PCB! Desolder and use a solder sucker or d e s o l d e r Wick, insert leads of new 1.2 volt 2000 mm rechargeables through PCB, make sure your soldering iron is turned on before you start anything, use the solder with flux built in, melt the solder around the Leeds and the PCB board been the leads over on the back side, set the PCB board back in your Braun unit before you assemble and flip the switch on and off to make sure unit works? Reassemble and reverse order to the video, use the jewelry screwdriver Philips, reverse the screws until they click and screw in snug do not over tighten, recheck make sure shave her powers on and off, reassemble and reverse order to the video Don't forget your side covers and make sure your switch on the shaver when you put the cover on still works, you're good to go for another 3 to 5 years, self clean shaver only after you clean it once a week, and the charging base and used green alcohol to refill the containers

First time I bought from this company and cost me dearly. Have been unable to contact the company as Amazon does not allow to do so. You're asked to contact Amazon who do nothing other than guide you how to return the item(which is very simple process). Well, I already installed 2 batts and one is bad, so I need to get a replacement for that one batt. No help other than return the entire order.

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