Description
Please Note 1: The maximum discharge current of imuto 1.5V AAA lithium battery is 0.5A. Due to differences in circuit design, some high-power remote control car、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. 2. If there is residual temperature on the surface of the battery after it is fully charged, please leave it for 30 minutes before use 3. During initial use, the battery charging indicator may not illuminate or may flash red, indicating that the charging base is misidentifying the battery. Try changing the charging slot and leaving the battery in the charging base for a longer period of time to see if this resolves the issue. 4.Our battery defect rate is one in a thousand. If you receive the goods and find that there are 1-2 batteries that cannot be charged normally, we will provide the best solution.

I’ve been using these batteries in a AA for about two years now and they work out great. This year I’ve found two that wouldn’t take a charge anymore, but to me because of all the batteries I go through between flashlights and outside thermometer just any device that takesAA batteries, including all my game cameras I’m saving money. I used to get the lithium AA batteries, but that was a lot of money for 60 this works out really well. I have 80 AA batteries. I also use them in all my game cameras I’m saving money. I used to get the lithium AA batteries, but that was a lot of money for 60 this works out really well. I think I have 40 batteries.

The charger comes with a charging cable but no USB power supply. You must provide the USB port and it needs to have a full 2 amp output. Even with 2 amps, I had 1 battery that didn’t start charging for at about an hour. The other 7 started charging right away. But one was so dead that it took an hour just to get it to start charging. If your USB power supply is less than 2 amps then it might take several hours for a battery to start flashing a green light. But in the end, all 8 batteries took a charge. Once the flashing green light stops flashing and is a solid green, the battery is fully charged. If there is no light at all, then there is either no battery in the slot or it’s completely dead and not accepting a charge. If that happens, leave it in there overnight if necessary. Eventually it should start charging. A delay to start charging doesn’t mean the battery is bad. It just means it is so depleted that it has to sit in the charger for a while before it will begin the charge cycle. It could be 15 minutes, it could be 15 hours. But unless you have a red light over that battery, leave it in there. Eventually it should start flashing a green light and then switch to a solid green when fully charged. And the next time you charge it, it should start charging right away.

Excellent batteries—and, even more importantly, an outstanding seller. One of the batteries I received turned out to be defective. I contacted the seller, and they responded immediately, sending a replacement that arrived within just a couple of days. That's the kind of customer service that earns repeat business. I'll definitely be buying more batteries from this seller.

I purchased a set of these batteries on November 2, 2025. I use IEMs (In Ear Monitors) at night to sleep. They work well as ear plugs to block noise and the music or commentary keeps me from focusing on any personal issues or problems that would tend to keep me awake. I use an old Sanyo MP3/FM player that runs on 1 AAA battery. The player draws about 70mA when running. If the backlight comes on, the draw jumps to 170mA. I measured these power requirements myself using a simple volt meter (obviously set to read amperage). I typically get in 8 to 10 hours of sleep. Therefore I need a battery with right around an 800mAh capacity to run the player through the night. In the past I've used rechargeable NiMH (Nickle Metal Hydride) batteries. I charge them with a PowerEx charger which tells me the capacity of the batteries after charging. I've found that most NiMH batteries rated as 1,000mAh quickly stabilize around 800mAh after several cycles, and at that rating, they run my radio all night. My last batch of NiMH were getting tired, and I'm a big fan of lithium ion batteries. So when I saw these batteries with a neat charger, I thought I'd give them a try. The charger is very easy to use and doubles well as a carrying case when traveling. It appears to charge the batteries pretty quickly and you can tell at a glance which batteries are charged and which need more time. The fact that the charger uses a USB C connector for power makes finding a power source quick and easy. At first I was very please with these batteries. The only fault (if you want to call it that) I could see is the fact that the batteries put out 1.5v pretty much until they go dead. Considering the nominal voltage of a single lithium ion battery cell is 3.6v to 3.7v, it's obvious each battery has its own BMS (Battery Management System) that regulates output voltage to 1.5v and controls discharge cutoff, charging voltage, and maximum charge. The effect is, the power indicator on your device will indicate a full charge pretty much up to the point the battery is drained. The good news is, you get nice steady voltage while it's running. The bad news is, you don't get much warning that the battery is about to quit. So why the one star? I used these batteries for about 60 days, one battery per day. The first four days were great. The batteries easily lasted the night. But then they started to fail after 5 or 6 hours of use. At first 4 batteries were reliable with the other 4 having effective capacities ranging around 400mAh. Please note the batteries are listed as being 1300mWh not mAh. Since the output of the battery is 1.5v the 1300mWh rating would equate to a mAh rating of 867 (1300/1.5). By the end of the 60 day period, two batteries were performing as advertised while the remaining six batteries had useful capacities of less the 400mAh. I don't know if the problem is the BMS circuit, poor quality lithium ion batteries or just sloppy quality control. It's a real shame because the idea is a good one and I'd love to find a set that worked as advertised. Unfortunately, at $20+ to find out, I think I'll stick with my NiMH batteries for a while. Some folks here apparently had good luck with these batteries. I used mine in a low drain device which they should have worked well in. As it turns out, I'll be pitching the whole rig in trash after a whole 60 days of use. Buyer beware.

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 bottom Now 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've only had this set of 8 AAA lithium rechargeable batteries for about 6 weeks now. They worked great, mainly for led headlamps, and other low power applications. Since then, I have already one battery that refuses to charge. I make sure I don't ever fully drain my lithium batteries to 0% knowing they are very fickle at that point and end up killing them quick. So even following a strong charging protocol, one batter now is not charging. I tried another lithium charger and it took wouldn't get it to charge . What a bummer, so be careful not to drain your batteries to zero before charging. I doubt that was the reason this one failed, nevertheless it did and I'm worried about losing another one or two. The idea was to save money on alkaline and nimh batteries with lower working voltages. Let's see if anymore fail. I'm disappointed right now for sure, 6 weeks was too short a time to fail.

Anybody who uses rechargeable cells with reasonable ampacity knows they are typically only 1.2V instead of 1.5V like Alkaline. While flashlights don't mind the difference, other devices do. These cells solve that problem and have a very convenient charging box.
