Tenergy AA 1.2V NiMH 2000mAh Flat Top Rechargeable AA Batteries with Tabs, 10 Pack

Good price, good battery. Rebuilt a battery pack for a Fluke meter. These batteries worked perfectly.

I was asked to replace battery packs in a portable frequency counter. The cost of premade packs are very expensive, but ~$20 for a package of 10 cells and a little time soldering them up I was able to create the necessary packs.In short if you are handy with a soldering iron, you can build your own battery pack and save a lot of money.Note I have used this manufacture's cells, though without solder tabs, before and had no issues with them over time.

We needed tabbed rechargeable cells and were happy to find these which work well in the application.

These 2000mAh batteries were an excellent choice to replace the handheld vacuum's old 1200mAh originals. The power is restored better then when it was new (2) years ago. I hope these will perform just as well.[edit] Sept 29, 2015The batteries have 'failed' me about 6mths ago and will not keep enough power the cordless vacuum cleaner. I have yet to test individual batteries from the pack to determine rate of failure. I will also assume the charging function is 'working'. I will update post if I discover differently.Lesson learned: spend more on better quality batteries. I'm reducing my review from 5 stars to 3 stars.

Exelente producto

They wasn’t what I thought I was buying and don’t know what I could possibly use this crap for

Edit: 18-months since the install, and while these still work, they've probably lost 50% of their capacity in a device that gets moderate use. While not necessarily a deal-breaker, lifespan is somewhat less than impressive.Original review:Used these to replace the ten dying 1,200mAh batteries in a big brand portable vacuum cleaner. The install would have been a little easier if the tabs were tacked on in opposite directions and if the tab holes were a little larger, but not big issues. These batteries were also very slightly larger than the batteries I removed, which made for a tight installation. But this isn't a problem with these batteries. Rather, the device had been designed around some slightly undersized (and low capacity) batteries. Getting these in place consequently required a little internal plastic trimming with an Exacto. The result, however, is that the vacuum now runs better (and perhaps a little warmer) than new. At any rate, I'm happy with these. And the new batteries cost far, far less than the a new vacuum.Just a note for anyone who doesn't realize, these aren't drop-in batteries. Installing them will require soldering, heat shrink insulation, and at least a basic understanding of electricity.

Replaced the batteries in an older hand vacuum. These were rated at a higher MAH rating than what I took out but were the correct size with similar tabs. Note if you are not careful, the tabs can break off, but the tops and bottoms of the batteries can be soldered to. After re-assembly of the vacuum, it was an amazing transformation. It now runs much longer and stronger, though it does take a bit longer to recharge the vacuum primarily because the larger capacity batteries take longer to fill. I am very happy with these, now to see if they last.
