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

I'm very pleased with the quality and ease of use of this charger. It can charge up to 8 AAA lithium ion batteries at the same time and it's easy to see which batteries are done charging and which ones are still in the process.

Have several flash lights that use 3 and 4 AAA batteries. Wanted longer battery life than from alkaline batteries. Bought Imuto kit with 8 batteries & charger. After charging, installed batteries in 2 flashlights that each use 4 batteries. I was impressed with noticeable brighter light coming from flashlights with LED bulbs. So impressed that 8 more CEFC lithium ion batteries, same as ones that came with the charger, were ordered for more flashlights. Hoping for longer battery life from reduced possibility of battery chemical leakage that occurs with alkaline batteries. Pictures show charger connected to my supplied charging supply with USB-C connector to mate with the Imuto charger. One picture shows charger top open, filled with batteries. Another shows lid with 8 green LED status lights. Lights flash during charging and become steady when batteries fully charged. Another picture shows front of the charger with lid closed. So far, really love the batteries & charger.

This is a solid, affordable charger for AA and AAA batteries. It charges at a reasonable, average speed and works well for most household devices that normally use disposable batteries. While the rechargeable batteries don’t last quite as long as traditional disposables, they perform well enough for regular use and save money over time. A great budget-friendly option for basic battery charging needs. They are compatible with every type of AA or AAA disposable battery devices.

Very good quality battery charger and batteries holding charge well. One battery is defective. I will contact supplier for replacement.

Lithium batteries are much better than NiMH batteries because they're 1.5v vs 1.2v. You just have to use their special charger so charging is consistent versus any charger. I'm certainly using these in place of alkaline batteries where devices need higher voltage and drain faster. It'll save me money in the long run. I have a set used in my door locks. They last just as long as alkalines. With my specific door lock, it doesn't seem to work with NiMH at all and drains alkalines every few months, so these lithium batteries keep the cost of operation down a lot. Just a note: one of the 8 batteries came defective and doesn't hold a charge. I sent a video in and they addressed my concern and replaced it. So far, they stood by their product as well as the big names, if not better, so my replacements will be of their brand.

The batteries work well, charging fast and better than NiMH batteries. Will buy some more.

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.

Context: I picked up this set to cut down on constantly buying disposable AAAs. I wanted something with good longevity, a decent charger, and reliable performance for everyday devices like remotes, small electronics, and lights. Experience: For the price, this set is fantastic. The charging case feels solid and well built, with a clean design and clear indicator lights. The batteries hold their charge well, and I’ve been impressed with how long they last between charges — definitely better than the typical low-end rechargeables I’ve used in the past. The constant 1.5V output means they perform consistently in devices that are sensitive to voltage drops. Recharging is quick and convenient, and the pack feels like a good long-term investment. Pros: Excellent price for 8 batteries + charger Sturdy, well-designed charging case Long-lasting charge with consistent 1.5V output Rechargeable up to 1600 cycles Easy to use and recharge Cons: None so far — they’ve exceeded expectations at this price point Verdict: A great value rechargeable battery set that delivers on performance, build quality, and longevity. Perfect if you want reliable AAA batteries with a well-made charger that should last for years.

Well made and works great

las baterias no sirven para nada, no parecen ser siquiera recargables, las use la primera vez y al quererlas cargar la caja no las detecta de manera correcta, algunas ni siquiera las detecta, si las muevo de lugar dejar de marcar, tarde en tratar de pedir reembolso ya que tarde en gastar la carga de las baterias, NO DESPERDICIEN SU DINERO CON ESTA COMPRA

Great product

These batteries work great. There was one that didn't work, but they replaced it for free.
