How many mAh does that convert to?** A: Volts x Amps = Watts. In this case: (mWh)/(V) = (mAh) = 2000 mAh A simple online converter: https://www.convert-formula.com/mwh-mah **Q: Can these be charged in the Nitecore smart charger?** A: No. I would not try. Kentli is not selling what are considered 'standard' lithium ion batteries of 3.7 volts. I seriously doubt the Nitecore could charge them correctly. Adding one of the Kentli chargers to a battery order is cheap and they work fine. NOTE: We might be surprised and the Nitecore charges the same way as the Kentli charger. But nothing I know of indicates that to be the case. Therefore, better safe than start a lithium ion battery fire. Such fires can be very nasty. **Q: What is the cut off voltage? Does the internal circuit prevent voltage dropping below 1.5v?** A: Yes, this battery cuts off at 1.5 V, but it holds that voltage much longer than other batteries in my experience. I had some devices that just stopped working when voltage dropped below 1.5 with NiMH batteries, but those same NiMH batteries just kept working for a relatively long time in other devices that could tolerate a lower voltage. The Kentli batteries are great for those devices that won't work with a lower voltage, I'm getting much longer times between recharges than with the NiMH batteries. **Q: If batteries have a manufacture date over 1 year, can they be returned ?** A: That's up to Amazon's return policies. I'm not sure that's an important issue with rechargable lithium anyway. But of course, the newer the better. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Satisfied customer. I learned some things, you'll want to know *by D***N on May 28, 2020* I've had these batteries and both kinds of chargers (the one that just holds four batteries, and the one with a build in flashlight).The batteries are mostly used in my Garmin Etrex Touch 35. It's a navigator for hiking, biking, etc. Using regular batteries in this is pointless. Too expensive. Regular rechargeable batteries are fine. The Kentlis are worth the extra price. They last much longer. (I should have measured the extra length before writing this. I'll do an update.) I think I'm getting an extra four hours. One important note: The regulator that keeps a constant charge results in the charge indicator showing full until the batteries are almost fully discharged. I always carry an extra pair, so no problem. However, there are certain items, like cameras, where you don't want to be doing certain things when the batteries suddenly go dead.If you want to use in an AM/FM radio: I have a CC Gozo (C Crane Company). It's a great radio, but it eats up the six AA batteries so quickly that it is expensive to use. Regular rechargeable batteries won't fit. The Kentli batteries work. Awesome. FM works really well! That saves a lot of money. BUT, there is a 1.5 volt regulator in these batteries that include a semiconductor. It causes interference on the AM band. So if I want to listen to AM, Kentlis are a no go in the Gozo.The Chargers: First, the special top requires that you use only the Kentli charger.Next, the charger with a flashlight: It holds four batteries, but only one is needed to power the light. You can charge one to four batteries at a time. There is a little indicator light for each battery that goes off when that particular battery is charged. USB plug. It's nice.Lastly, the four battery charger without the light. It charges one to four batteries. My favorite feature is that each slot has a light that is red when charging and green when charged. USB plug. I like it. ### ⭐⭐⭐⭐⭐ Good replacements for 1.5v other batteries. *by S***S on November 13, 2020* If you are looking for the ideal battery alternative to the regular 1.5v alkaline, these are it for most electronics. They are Li-On which is superior to Ni-MH rechargeables in density and holding a charge.The only problem I had was with a 25 year old Walkman radio and a 33 year old travel Radioshack radio. For some reason the AM receiver would not work, I would just get static. I rechecked the integrity of the radios by replacing the Kentli Li-Ons with Ni-MH and the AM would work fine.These Kentli batteies require the Kentli charger, not any Li-On charger will work. But there are some competitors appearing on the market. And avoid the non- rechargeable Li-Ons by the 'energy bunny' as they don't hold a charge as I found out to my disgust. ### ⭐ Don't bother *by O***S on January 20, 2023* Bought 3 brands at the same time to find a good winner. These weren't them. One never worked. One only had one use cycle before never charging again. One had just two recharge cycles before not having any life after the charge - just seconds. The last one became extremely hot to touch during its third charge. Might have been the charger, which quit, but the battery was toast also. --- ## 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.hr/products/129302533-constant-1-5v-aa-rechargeable-battery-3000mwh-lithium-ion-polymer](https://www.desertcart.hr/products/129302533-constant-1-5v-aa-rechargeable-battery-3000mwh-lithium-ion-polymer) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-24*
