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.
