Tenavolts NANFU Rechargeable Lithium/Li-ion Batteries, AA rechargeable batteries, Micro USB Charger included, Constant Output at 1.5V, Quick Charge less than 2 hours, 2775 mWh electrical core power- 4

Tenavolts NANFU Rechargeable Lithium/Li-ion Batteries, AA rechargeable batteries, Micro USB Charger included, Constant Output at 1.5V, Quick Charge less than 2 hours, 2775 mWh electrical core power- 4

Q: Are these truly 1.5v or are they 1.2v like all of the other rechargeable AA batteries?

Yes, they maintain a steady 1.5V. 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?

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

These are lithium ion. Lithium polymer are the flat packs like they use in phones.
