- Reviewed in the United Kingdom on 22 October 2024Been using these for about 4 years now for blink camera still holding a good charge
- Reviewed in the United Kingdom on 6 July 2024I bought these for my blink cameras, they work much better than eneloop which say the battery is always empty even with fresh batteries.
Nice compact charger. Have bought 2 packs now and all seem good.
- Reviewed in the United Kingdom on 23 September 2023I had these in my smart lock, and first charged them after 8 months of use without issue. However, after this charge the smart lock only went about 2 weeks without warning of low battery status. Two batteries had fallen to 0V.
Recharged again, after about 2 weeks one battery had fallen to 1V and the other to 0V so can only assume these batteries have failed.
Edit: I had a response from the manufacturer who said to send back for a replacement.
- Reviewed in the United Kingdom on 15 April 2021Excellent long life batteries. I wish they sold just batteries on Amazon so I could buy more without another charger

- Reviewed in the United Kingdom on 22 February 2024On paper these look great. In real life for £36 they are a let down. I got one charge out of them before one of the cells refuses to fully charge... Or at least the blue led stays lot permanently when in the charger.
Also the charger uses micro usb not usb c which is disappointing.

PhilippReviewed in Germany on 18 June 20233.0 out of 5 stars Leicht Batterien mit geringer Laufzeit
Leichtere Batterien als der Standard AA, aber dafür weniger Laufzeit.
Verwendt werden die Batterie von mir in einer G305 und machen die Maus etwas leichter. Laufzeit ist dafür aber ungefähr 10h weniger als bei anderen AA Batterien.
Nathan FlaneryReviewed in the United States on 3 February 20245.0 out of 5 stars 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.

guillian2606Reviewed in France on 19 March 20234.0 out of 5 stars Pile rechargeable qui fait l'affaire pour le moment par contre à voir sur le long terme
J'utilise les piles rechargeables pour les caméras de surveillance blink de chez Amazon. Cela fonctionne bien même si au niveau longévité je dois les changer environ toutes les trois semaines ce qui est un peu plus qu'avec les piles non rechargeables par contre les économies se feront sentir rapidement une fois le prix d'achat amorti. A voir cependant sur le long terme.
