Description

Please Note 1. Maximum Discharge Current: The maximum continuous discharge current of imuto 4200mWh AA lithium batteries is 2A. Certain high-power devices — including high-draw remote control cars, ultra-bright LED flashlights, and LED headlights with high/turbo modes — may draw current exceeding the battery's rated limit. Sustained operation at or beyond the maximum discharge rating may cause the battery to heat abnormally. If your device features a high-brightness or boost mode, please verify its current draw against the battery's specifications before use. 2. After Charging: If the battery surface feels warm immediately after a full charge, allow it to rest for 30 minutes before inserting into your device. 3. First-Time Use: During initial use, the charger indicator may not light up or may flash red. This can occur when the charging dock is calibrating to the battery. Try reseating the battery in a different charging slot and leave it in the charger for an extended period to allow proper identification. 4. Quality: Our battery defect rate is one in a thousand. If you receive a unit where 1–2 batteries fail to charge normally, we will provide the best resolution.

    • Excellent choice over disposable batteries
Set name: 4AA 3600mWh with Charger
These have been a huge game changer for my Blink cameras. They need lithium ion batteries and with several cameras I was using a lot of batteries. These work every bit as well as disposable batteries. They charge fairly quickly and store in the charging case when not in use. Whether you are using them for cameras or everyday items around the house these are a great purchase. The money I have saved is substantial plus I'm not throwing out so many batteries. ... show more

    • Best batteries ever
Set name: 4200mWh 8AA+8 slot charger
Batteries work great. They last a really long time in use. They recharge quick. They save me a fortune over buying alkaline batteries. I am going to move all my battery operated items to these batteries.

    • Not bad! Just one flaw.
Set name: 4AA 3600mWh with Charger
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. ... show more

    • Affordable and effective!
Set name: 8AA 3600mWh
I love these batteries. Once in a while one will stop charging and that is a bummer, but the ratio is so low that I cannot complain. In terms of rechargeable batteries, these are superior to other brands and the charger is very easy to use.

    • Excellent product and customer service
Set name: 8AA 3600mWh with Charger
These batteries hold a charge for much longer than other lithium batteries I’ve had in the past. But most importantly, their customer service is excellent. When a battery failed, I contacted Imuto through the Amazon website and they immediately responded and offered to replace the faulty battery with a new one. Any product may occasionally fail, but what’s important is how the manufacturer responds to such eventuality. In this case, the response was fast and fully satisfactory. I totally recommend this product and brand. ... show more

    • Charging correctly and happy with purchase so far
Set name: 4200mWh 8AA+8 slot charger
Review Image by mary gretchen lahman
I just received the 8 batteries in their charger box. They are now charging correctly so I am satisfied for now. I only just got them so I cannot say how long the battery life is nor can I comment on their value for the money as I do not know enough information yet. I can say the charging speed is not very quick because I have been waiting for at least 45 minutes and only one of the eight is charged. I am happy with the charging box which keeps the batteries stored all together in one convenient place. I tried one of my old rechargeable Energizer batteries in the charger box and it did charge with a blue light so it is compatible, which is great because I have quite a few of them. Overall, I am good with my purchase so far. I just hope the batteries last a decent amount of time before they need recharging. ... show more

    • Short Life - would Not buy again
Set name: 4AA 3600mWh with Charger
Bought these for use in a medical device which needs a single AA cell to save $ and going thru batteries endlessly. Energizer Ultimate Lithium batteries would last about 3 weeks. Started using these rechargeable LI batteries and was initially impressed. They charged quickly and the cells were each lasting 3-4 weeks. After 6 months 1 of the batteries showed failure on the charger and would no longer charge. After about 1 year, the remaining 3 cells were only lasting about 2 weeks. At the 18 month mark, a 2nd cell has now died and won't recharge. At this point no savings over the Energizer batts. Another thing to note is that lithium ion batteries will hold their voltage until the very end of their life and then die suddenly. This is just a characteristic of lithium batteries and is not a defect. But users need to be aware that there is no warning that the cell will die suddenly and need to be replaced. ... show more
