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 ### ⭐⭐⭐⭐⭐ Tenavolts Konstante1.5V Leistung AA Lithium Wiederaufladbar Akkus (x4) *by B***R on 11 November 2025* Entspricht den Erwartungen. ### ⭐⭐⭐⭐⭐ Un buon prodotto *by M***A on 8 January 2022* Confezione, qualita' e prime impressioni molto molto positive.

GREAT charger! *by N***Y on 3 February 2024* 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. ## Frequently Bought Together - TENAVOLTS 1.5V AA Lithium Rechargeable Battery, 1.8h Fast Charge, USB Charger, Constant Output at 1.5V, 2775 mWh, 4 Count with Charger - TENAVOLTS 1.5V AAA Lithium Rechargeable Battery, 1.8h Fast Charge, USB Charger, Constant Output at 1.5V, 1110 mWh, 4 Counts with Charger --- ## 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.vu/products/542589201-tenavolts-nanfu-rechargeable-lithium-li-ion-batteries-aa-rechargeable-batteries](https://www.desertcart.vu/products/542589201-tenavolts-nanfu-rechargeable-lithium-li-ion-batteries-aa-rechargeable-batteries) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-07*
