GREAT charger! - These have really held up well over the last 3+ years compared to many other brands I've tried. They still have a shelf life of more than 6 months which isn't bad after 3 years. They have also never given me any problems after the manufacturer quickly replaced 2 AAs that had issues when I first got them. Sometimes these lithium rechargeables can have problems charging if the power drops too low for too long. The chargers just don't detect them and won't charge. Some brands will overheat while charging and take forever to charge. But I have never had these problems with Tenavolts. They also thought of simple things like having the LED light on the battery go OFF when they are fully charged rather than stay on once they are charged which begins depleting the battery power as soon as they are charged. That may sound like a "no brainer," but a LOT of lithium's have a light that stays ON, full blast, when they are charged. Those are always the bad ones that don't last. If you're going to try rechargeable lithium AAs and/or AAAs, the Tenavolts charger is a "must-have." It is a super simple charger. No fancy lights or electronics. Because of that, it will charge ANY brand of lithium AA or AAA if the battery is salvageable. I've had countless other brands of rechargeable lithium AAs & AAAs that won't charge on their own brands charger, but the Tenavolts charger will charge them. I would have had to toss out many of them if it weren't for this charger. Sometimes other brands get "stuck" and their own manufacturer's charger won't detect them. But because this charger is so simple, it will "jump start" them so the other charger can finally detect them. Then they work fine after that. And yes, it will even charge lithium's that have a USB charging port built-in, often better than the USB port. Review: Amazing - After going through countless batteries for my hands free toilet. After several weeks I am amazed at how much power the batteries still have. Motion sensing is perfect due to the 1.5v. If you have products that you use frequently these are a must. Great speed while charging. Great performance. Bring another set for my Xbox controllers. ## Features - HIGH ENERGY CAPACITY - Includes pre-charged Tenavolts AA high-capacity rechargeable batteries, each with 2775 mWh. Great use for high energy demand devices including insulin pump, toys, remote controls and portable audio players - 1.8 hours for full charge: get a full charge in 1.8 hours. Much faster than traditional Ni-MH rechargeable batteries that need 3 hours to fully charge - LONG-LASTING BATTERIES, LESS WASTE - Tenavolts can be recharged in 1,000 cycles. As discarded batteries are terrible for the environment, from the perspective of the environment, rechargeable batteries are more economical and better than normal batteries for the environment ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08B397M7N | | Antenna Location | Camera, Clock | | Battery Capacity | 750 Milliamp Hours | | Battery Cell Composition | Lithium Ion | | Battery Cell Type | Lithium Ion | | Battery Weight | 18 Grams | | Best Sellers Rank | #331,926 in Health & Household ( See Top 100 in Health & Household ) #931 in AA Batteries | | Brand | TENAVOLTS | | Customer Reviews | 4.5 out of 5 stars 3,674 Reviews | | Manufacturer | NANFU | | Model Name | AA | | Number of Batteries | 2 AA batteries required.

Others have done tear-downs on these, and it appears inside is a 3.7V Li-ion cell that has been brought down to 1.5V using miniaturized electronic circuitry. One caveat - these batteries will maintain a steady 1.5V until the very end of the discharge cycle, and then suddenly drop the voltage. Thus, keep a few spares handy. **Q: Your first generation tenavolts state in title that they are "lithium/li-ion", so is this interchangeabl or is this lithium battery different? how so?** A: Exactly! The cathode/anode materials of TENAVOLTS are LiCoO2/Graphite, which are widely used in rechargeable battery. They would be interchangeable and reversible when charging and discharging. **Q: Lithium ion or lithium polymer** A: These are lithium ion. Lithium polymer are the flat packs like they use in phones. **Q: Are these low self-discharge?** A: yes ## Customer Reviews ### ⭐⭐⭐⭐⭐ Still some of my best lithium rechargeables after more than 3 years.

After several weeks I am amazed at how much power the batteries still have. Motion sensing is perfect due to the 1.5v. If you have products that you use frequently these are a must.

The 10 V batteries and charger. First of all the batteries. The batteries are still not quite as powerful as the ultimate lithium batteries by energizer, but, they do still pack a fair amount of power. The battery charger is rather interesting. It will only charge AA and AAA cells. The connecting cable can be any USB to micro USB connector you have. It has to be a micro USB, one with the two little pins on the plug. What the firm says is true. Batteries take about two hours to charge. I guess that, in my zoom essential recorder, the batteries are to give me roughly 8 1/2 hours of solid record time before needing to be changed. I am certainly not done buying more batteries for this charger. I anticipate buying much larger quantities both of AAA end of AA batteries. Finally found the match that seems to work perfectly. --- ## 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.at/products/222921328-rechargeable-batteries-aa-lithium-2-pack-w-usb-charger](https://www.desertcart.at/products/222921328-rechargeable-batteries-aa-lithium-2-pack-w-usb-charger) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-07-11*
