Review: Still some of my best lithium rechargeables after more than 3 years. 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: Great overall, know what you're getting into. - They pack a punch until they don't, but that's how lipos work. Just a heads up no real low battery warning they just quit working. Great overall. Know what you're getting into.

## Questions & Answers

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

### ⭐⭐⭐⭐⭐ An AA sized regulated 1.5 volt power supply.
*by V***Y on December 31, 2019*

If your device is well designed, it will work normally as your alkaline or NiMH battery gradually decreases in voltage. The Tenavolts are for those devices that are very fussy about the voltage. The batteries are expensive, but they perform exactly as advertised, and deliver an extremely constant 1.5 volts. And they can handle high current spikes easily. I use them in motorized Nerf blasters which are famous for eating batteries. One last thing, "Nanfu Direct". I'd never heard of the company, so I didn't know what to expect. Well, one of the 12 Tenavolts batteries I got proved defective. It took a few weeks to find this out. I emailed Nanfu through Amazon's link, explained what happened, and asked if they could replace the bad one. I got the "thank you, please allow 1-2 days for a response" message. Instead of 1-2 days, they responded within hours, apologized for the problem and immediately sent a replacement. I'm impressed. update, October 13, 2020. One reviewer felt that the battery capacity was much less than advertised. However, my batteries all test near the advertised number. The printing on the battery says "2775 mWh". My measurements of 4 batteries averaged 2300 mWh, which I think is pretty close. Some confusion may be the difference between "mah" and "mWh" (milliamp-hours vs. milliwatt-hours; milliamps and milliwatts are different). Most batteries quote capacity in mah. If the Tenavolts people had used mah, they would have printed "1850 mah" on the label (2775 divided by the voltage, 1.5). By this measure, the batteries I tested averaged 1556 mah. Not quite 1850, but not way off either.
