imuto Rechargeable AAA Batteries Lithium 8 Pack with Fast Charger,1300mWh 1.5V Constant Output Triple a Lithium Batteries 1600 Cycles Long Lasting

I recently purchased the imuto Rechargeable AAA Batteries Lithium 8 Pack with Fast Charger and I couldn't be happier with my choice! The compact design is not only aesthetically pleasing but also practical, as it serves as both a charger and a storage solution for the batteries.This pack includes eight rechargeable batteries, which I have been using in my keyboard and remote control. The 1300mWh capacity and 1.5V constant output ensure that my devices run smoothly without any interruptions. I appreciate the long lifespan of these batteries, rated for up to 1600 cycles, which means I can rely on them for a long time.In the long term, switching to these rechargeable batteries will definitely save me money compared to constantly buying disposable ones. I highly recommend the imuto rechargeable AAA batteries for anyone looking for a reliable and cost-effective power solution!

I'm a huge fan of this. Comes with the rechargeable batteries, the charging unit which also doubles as a storage unit. It makes it easy to not lose track of batteries while they are swapped out of other devices and in need of a change. I leave this in a corner of my office desk, and know that the battery(ies) will be charged when I need them.The batteries themselves have been pretty solid since delivery and I've had no problem.The charger gives you a clear indication (with the lid down!) of the state of the batteries. When you see green, you know it's good to go!Good value for money, especially when considered compared to the old school non-rechargable batteries. I highly recommend these.

This is not a Vine review: I bought the set of 8 imuto AAA batteries with the charger for $22 in Mar 2025.- charge the batteries when you receive them: mine arrived at about 40% charge. No big deal - just charge them when you get them.- the batteries can be charged in my XTAR VX4 and EBL C708S3L chargers in addition to the one in the kit.- the charger included with these batteries will **not** charge NiCD, NiMH, or my other rechargeable 1.5V Li-Ion cells - it's for these imuto cells only.I have several chargers that will charge 1.5V rechargeable Li-Ion cells (including these), so the included charger isn't much interest to me. That said, The charger's physical design is appealing but it has some aspects I don't like:- as mentioned above, the charger only works for these specific batteries (though the batteries can be charged in other chargers)- this charger only works for AAA batteries. Consider whether the imuto kit that has 4 AA and 4 AAA cells might make more sense- for some reason they put the USB-C power input on the lid so it ends up being a clunky thing that kinda gets in the way. It's not a deal killer, but I don't understand why they didn't put the input power jack near the bottomNow the good news - these AAA cells have a true capacity around 720 to 800 mAh (equivalent to 1080 to 1200 mWh). It seems that the capacity improves a bit (10-20 mAh) after a few charging cycles. Now you might think since imuto claims these cells have an 865 mAh/1300 mWh capacity that this means you are only getting 85% of the claimed capacity - and you'd be right.However in my limited experience, getting 720+ mAh from a rechargable AAA cell is pretty good. At the price these were when I bought, the cost per cell is $2.75 which is very good - and that's considering the charger as free. Other 1.5V rechargeable Li-Ion AAA cells I have from a better-known brand that claimed 800 mAh/1200 mWh capacity tested to only about 320-350 mAh capacity at a higher cost. Less than 50% of the capacity of the imutos for 20% more money.I think these cells are a good deal even if the true capacity is only 720+ mAh. I wish imuto - and all brands - were more accurate with their claims.Note that the listing has this buried in some small print (I think this applies to many 1.5V lithiums):"Please Note: The maximum discharge current of imuto 1.5V AAA lithium battery is 0.5A. Due to differences in circuit design, some high-power LED flashlights and LED headlights may cause the battery to work overload and cause abnormal heating. If your device has a high brightness/strong light mode, please pay attention to the high current requirements of the device. Long-term full current output and over-current output will cause abnormal battery heating."The bottom line from me is: this kit is a good value for the batteries alone especially when there's a deal active. But avoid using the batteries in high drain devices. Just an FYI - I bought a 2nd kit at the sale price.**Another update** (Apr 2025):I stumbled on a chart imuto has on another of their rechargeable battery listings (www.amazon.com/dp/B0DCHTZBT8) and I'm adding it to this review. The chart indicates that while the "cell energy" is 1300 mWh (which is what is advertised in the product listing), the "rated energy" is 1170 mWh and the "rated capacity" is 780 mAh. The "cell energy" is said to be the "actual total energy" (theoretical I guess) while the "rated" numbers are the "actual" energy or capacity of the cell.In the chart, imuto defines these values as:- Cell Energy: Actual total energy of the battery cell- Rated capacity: Actual discharge capacity- Rated Energy: The effective energy actually deliverable by a battery (typically 5%-15% energy retention is required in rechargeable batteries to ensure system safety and cycle life)Note that the "Rated" numbers stated by imuto in that chart match up with the numbers that came out of my testing.So you can believe those two columns of the chart. It seems that advertising the theoretical energy of a cell is very common in the battery universe, leaving it to consumers to figure out how much juice **you** will be able to get out of the cell. I wish the "rated" numbers were what all vendors would publish/advertise.I think that chart probably gives people the kind of capacity you can really expect from many other vendor's batteries, not just imuto, when they advertise a particular mWh number. I appreciate imuto providing this chart, though it took luck for me to stumble on it.

7 out of the 8 batteries worked fine but the one wouldn't charge and the charging light just blinks red which means an incompatible battery. Apparently defective. I put in for a return and messaged that I just need one replacement battery. I'll see what they say but I think I'll be sending the entire set back. Customer service is refunding the cost and I'll buy another set. I think it was just one defective battery, so I'll have backups now. Also, found out you can't ship a defective Lithium battery back to Amazon, but they had sent me a return label and when I read the instructions it said not to send defective batteries, it could result in an unsuccessful return/recycle. Customer service followed through and I bought another set. They charged up like they should and I'll see how they perform.

They work very well, they charge quickly and I like that 8 batteries come while some are charged others are in use I use them for controls and toys

My son burns through AAA batteries like wildfire—mostly because he’s obsessed with his walkie talkies, and they seem to drain batteries faster than I can replace them. I was getting so tired of constantly buying new batteries, not to mention the waste, so I finally decided to try these Imuto rechargeable AAA batteries—and I’m so glad I did.This set has been a total game changer for us. The batteries charge quickly and hold a charge really well. They’ve lasted through tons of playtime without needing to be recharged constantly, which is impressive considering how often my son uses his gadgets. The charger is super easy to use and doesn’t take up much space, which I appreciate.We’ve already saved a ton of money not having to buy new batteries every week, and it feels good knowing we’re making a more eco-friendly choice too. If you’ve got kids or any devices that go through AAA batteries fast, this is seriously worth the investment. I wish we’d switched to rechargeable batteries sooner!

Came in pack of 8 rechargeable AAA batteries. Long lasting, I've been using them in my keyboard and mouse. Fast charging and the charging box is different and convenient to store and regarge the batteries. USB C charging port.
