XTAR AA 2000mAh / 3300mWh 1.5V Rechargeable Protected Lithium-Ion Lithium Nickel Manganese Cobalt Oxide (LiNiCoMnO2) Button Top Battery - Bulk

Very good batteries for the price and like most of Xtars stuff its dependable.

I bought 12 of these, with the X-tar charger. I opened them up, charged them up, and tested them in a new flashlight. They performed exactly as I would expect them to, with long drain times. Then I charged them back up.

So this review is only for one round of using them, and they were great. If for some reason my opinion changes, I will w...Read MoreRead more about I bought 12 of these, with the X-tar

Purchased 8 of these with the associated charger. They charged up nicely and I checked the output voltage afterwards. All 8 were within a very small margin of 1.5V. So far I've used them in a flashlight and a 4xAA based soap dispenser. The manufacturer of the soap dispenser cautions that NiMH rechargeable batteries will not work so I figured I'd g...Read MoreRead more about Purchased 8 of these with the

ive these a try. They work, but the diameter of these cells is slightly larger than a standard AA. They kinda fit, but the closure couldn't be screwed down all the way. Also found that I couldn't store them in the AA holders I have. After pushing them into about half way the resistance was great enough that I decided I'll need to find different holders for these cells. I like that the charger is USB C based as I believe time has passed for any new USB accessory to be micro B. Bottom line - so far they seem to perform as I expected, but really haven't had them long enough for a final assessment. The slightly larger diameter is something to keep in mind and is entirely dependent on the application. Read LessRead less about Purchased 8 of these with the

Purchased 4 of these for my security cameras. One of the four suddenly died in use and would not recharge. Reads zero volts with a meter even after being on the charger. Looks like an internal circuit fault of some sort.Warranty period is only 15 days which would seem to only be useful in DOA situations.

When they go dead they'll go dead suddenly, and will read exactly 0.00 volts (as you'll discover if you have a voltmeter to test them). Don't let that fool you. The sudden 0.00 volt reading is normal behavior for lithium batteries. Just put the batteries back in the charger for two or three hours and they'll be fully charged again, and show 1.51 v...Read MoreRead more about When they go dead they'll go dead
