The charger I am replacing was fine and will keep it as a spare, but only had a light whopping charging was occurring ### ⭐⭐⭐⭐⭐ The best ive found. *by on Reviewed in the United States July 31, 2026* These are the best batteries ive found . I have bought both the triple A and the double A and they last forever. I need a few more and bought them again. I tried a couple other brands ad the one only last at most 6 months . I will only be buying these when i need more. ### ⭐⭐⭐⭐ Looks good, so far *by on Reviewed in the United States June 29, 2025* These batteries come with a nice USB charger. As soon as I received these batteries, I charged the batteries from my desktop computer and almost all of them were done within a couple of minutes. In other words, they had maintained a full charge while stored and shipped. A few of them took several minutes to reach a full charge, but that's still very good, as far as I'm concerned.I tried to check the capacity of the batteries by using an Opus charger, but that didn't seem to work. I got strange readings and a "null" reading partway through the "Charge/Test" cycle. So I don't really know how good the batteries are without knowing if they have the proper capacity. If I find a way to check the capacity later on, I'll take away a star if the capacity is too low and I'll ad a star if the capacity is what it is supposed to be.I bought these batteries for use in a blood pressure monitor. I had been using Panasonic NiMH batteries in the blood pressure monitor, but those batteries are less than 1.5 volts and when the voltage starts dropping, the blood pressure monitor starts signaling that the voltage is getting low. Now, with these new Lithium Ion batteries, I'm expecting to get more blood pressure readings before a lower voltage is reached.Update: These batteries solved my blood pressure monitor problem. I've checked my blood pressure about 30 times or more and the batteries are still going strong. I still have to check the actual capacity if my charger/tester will allow that.Update: My Opus charger doesn't seem to work on a Charge/Test cycle with these batteries. I tried again and it didn't work. So I'll just have to go by performance instead of a capacity readout for these batteries. The 2 in my blood pressure monitor definitely seem to be doing well. Eventually, I'll be able to try all of them in the monitor and that will tell me more. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/589661881-kratax-aaa-rechargeable-lithium-batteries-8pack-1-5v-1100mwh-li](https://www.desertcart.jp/products/589661881-kratax-aaa-rechargeable-lithium-batteries-8pack-1-5v-1100mwh-li) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-20*
