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

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.

I use these in OpsCorr headphones that need 1.5V, so non-lithium rechargeables don't work. One thing to note during comparisons is that these are rated at 1300mWh, but the non-lithum rechargeables are in mAh. Dividing 1300mWh by 1.5V yields 866 mAh. These are the longest lasting rechargeables I've found. They don't hold a candle to the non-rechargeable Energizer Lithiums, but those are around $2 each. My 900mWh EBLs last about 2 hours in my OpsCore. These last 3 hours. I liked them so much that I've ordered a second set. Another advantage is that you can purchase just the batteries, but EBL only sells their AAAs with a charger.

This rechargeable AAA batteries is well designed and has good light indicators that show how many units are yet to fully charge. The batteries charge quite fast. I have tried to read the voltage level using a DC volt meter and noticed that they get up to 95% charge which is great. I have only charged it once and have been using it on my remote since it got delivered. They seem to last quite well after charging.

So this works great; however I use it in light that I got with a cardinal on it from my mom's wake... so the batteries I'm assuming are always running, but the light never comes on till the evening. These batteries lasted about a week or two before they started sinking the light inside again. They seem like good batteries maybe it's the actual item I have in not sure, but I think if you used them in remote or toys they may give you a more of a life span for that item.

I recently bought these rechargeable AAA batteries for my son’s toys, and they’ve been fantastic! They last way longer than regular disposable batteries, which saves me both time and money. Fast charging gets to full power quickly, so no long waits. I like the most it’s has comes in a convenient case to keep them organized.

Best way to continue to use batteries instead of throwing double AA and triple AAA batteries. This charger and batteries have helped me save money from continuously buying new batteries over and over. I also use it for my xbox controller(s) and tv remotes.

I really like having rechargeable batteries I bought several of these in AA and AAA. It works very well. Put them in all my flashlights now and don’t have to worry about buying new batteries very convenient good value. They seem to lasted quite a while even compared to conventional batteries. I haven’t had any die on me yet so I can’t tell you how long.

Only one of the batteries was bad. I love the charging case and storage container. Very nice and practical, but have to give it 4/5 for the time being. Since I just got this today, I don't have anything to say on the longevity, the capacity is established on the site, but I'll monitor that and the life as the days go on.
