imuto 1.5V Voltage AA Lithium Rechargeable Batteries, 3600mWh AA Lithium Battery 8-Pack, 8 Slot with Smart LED 3H Fast Charging Storage Box, 1600+ Cycles, for Smart Lock, Xbox, Blink Camera

I decided to buy these Lithium AA batteries because they hold a charge longer and are less likely than Alkaline to have leaks. However, after a year, one of the AA cells behaved strangely during recharge. The LED turned solid red instead of solid green. It fixed itself after a few re-tries. So I contacted support, and they promptly sent me a set of replacements.

Seems like I have reviewed this item at least twice but it keeps coming up for further review. It works as advertised.

I’m very impressed with this item. This charge case system makes it easy to change out & re-charge the batteries. The re-charging of the batteries makes for a very long lasting charge, at least initially. It makes this investment very worth while because of the time and energy saved with much fewer exchange times.

I use these batteries for the controllers of my meta quest 3, its literally just standard AA batteries with rechargability. The case reminds me of wireless earbuds which makes it look cute, it has charging lights on the top of the case, which i love. The one flaw is the case itself doesn't have an in-built battery, so you cant recharge the case itself. If it had that, it would be worth everything. The sound when you close the case is pretty good. The value of money is somewhat decent, could be better. But hey, if it works, it works! Battery life as I mentioned above is pretty good, power draws into my controllers like a dream, theres no power drops whatsoever, its very smooth. I even used the one thing that consumes battery power like crazy, AND IT STILL BARELY DROPS ANY FASTER! if it was actually lithium, it would most likely prolong the battery life, which would be ABSOLUTELY BONKERS. If this manufacturer makes them, then take my money. i wouldn't care about the price, I would just snatch one and pay for it. The size is a bit of an understatement though. It is NOT pocket friendly, if anything i would put it in my backpack pocket and it would fit perfectly. If you don't have big pockets, I wouldn't recommend it, but if you don't need pockets, definitely snatch one and see for yourself. These things are pretty good. Definitely a must have.

These are 1.5v Li-ion batteries.and they cannot be charged in a charger intended for Ni-MH batteries AND the included battery charger will destroy Ni-MH batteries if used to charge hem. Also be aware that the included Li-Ion Batteries cannot be charged with any charger intended for Ni-MH batteries because the charging voltage is too low. These 1.5v batteries are intended for use in my AA battery powered remote controllers that used so little battery power that every regular Alkaline AA that I have used in the past, started leaking badly before the battery ran out of power and destroyed the remote controller due to the corrosion of the internal parts long before there were any bad symptoms showing up. Rechargeable batteries have different chemistry and do not leak like Alkaline Batteries.

These batteries last 3 times longer than standard batteries in my game controller, and 2 times longer than Ni-ch rechargables. Works great in flashlights and remotes to.The recharge time is fast, but with 8 batteries that is not much of an issue. The charger is compact and fits anywhere you want to put it and generates no noticable heat. The batteries themselves fit perfectly into everything I have tried them in.

I was pleasantly surprised by the quality of these rechargeable batteries. Fast charging and they lasted longer than expected in my back yard trail camera. I have lots of critters running around at night and these batteries don't disappoint.

One battery out of four went open on first charge would like replacement. Unmatched cell.

I’ve been really impressed with the imuto rechargeable AA lithium batteries. I use them in my outdoor cameras, and they hold a long, steady charge even in consistent –30°C temperatures, which is something most batteries struggle with. These have been incredibly reliable through the coldest stretches. The constant 1.5V output keeps my cameras running smoothly, and the fast charger is a great bonus. I also love that they come in a sturdy storage box — super convenient for keeping everything organized. They last a long time, recharge quickly, and perform just as well (if not better) than more expensive brands I’ve tried. For anyone using outdoor devices in harsh weather, these are a fantastic choice.

Works very well, charges well and easy and batteries last long and hold there charge

This thing is great! Im going to order another one. Super handy. Use for my Xbox controller. Two go in and there are two on standby. The charging is relatively quick and they last in my controller for quite a long time.

One of the 8 batteries was unable to recharge. Sent an email to the support. Quick response within a day asking me to send them a short video to show how it was recharged/unable to recharge. Emailed them a couple of video as requested and received a new set within 2 days. Very impressed with their after sales services. I used these batteries for camera, flashlight, Blink doorbell and outdoor cameras. They work fine and same as, if not longer than, the Energizer Li non rechargeable batteries included in the Blink package. Although unfortunately, there is one failed battery, the quick response and replacement (8 for 1 failed battery) compensated for the minor shortfall. Understanding that occasional defeated product did happen, the key is the good after sales service that stands behind their products makes happy customers.

These iMuto Rechargeable Lithium AA batteries are working fine in my Blink security cameras, even in colder temperatures (1-5 degree Celsius). The charging case is compact and convenient and there 4 separate LED lights showing which cells are charging and when charging is complete. I'm not sure why rechargeable lithium batteries show capacity in mWh but the 3600mWh capacity is equivalent to 2400mAh. The batteries after a full charge were showing a voltage of 1.62V. So far, these batteries are working good.
