4pcs KENTLI PH5 1.5v 3000mWh rechargeable Lithium AA PH5 battery with USB Charger

I ordered the 2800mwh, but they sent the 3000mWh ones.I bought these to use in an ATN 3-14 digital optic, & so far, I'm very impressed.Where regular AA batteries would run the device for 10-15 minutes, these batteries have been able to run the device for upwards of 6 hours, and showed no sign of getting ready to run out of power. Not sure how many charge/discharge cycles I can get out of them before they fail, but hopefully it'll be many.They are expensive, but from what I can see so far, they are worth it.

I purchased a pack of these batteries about 6 months ago, charged them once and tried them in a door lock but the lock didn't work at all as if the batteries were dead. I didn't have my voltmeter so I stuck them in a drawer until a couple weeks ago and forgot I had them. I found them again and decided to try them once more. I charged them with the included charger until a green LEDs and tried them in several other applications. A flash light as well as several other electronic devices but none actued as if there was any power to them. I finally decided to try my voltmeter on them and found two of the batteries registered at about 1.5 volts, one was about 2.8 volts and the other battery was COMPLETELY DEAD even after just coming out of the charger showing a green charged light again.I'm not sure what is going on with their QA/QC here but I am not happy at all! A 50% failure rate is not acceptable for expensive lithium batteries and that is on the first try of these! It is far too late to return these so I am hoping the company will see this and consider replacing the two bad ones. If so, I will be much more likely to raise my rating of these providing the replacements work.

lasted longer than most others and worked great in item

What an awesome product. I would get 20 or so photos with my Kodak camera using regular batteries. These put me closer to 150 photos per charge.

Charger could be better but can't complain about the batteries. the last WAY longer than other rechargeables and alkaline, just wish they cost less so I could get more of them

Both the batteries and charging unit work great! We have been using both items daily and switch batteries every other week. So far so good.

still observing...

The best constant 1.5v battery on the market, long lasting and well worth the money saved on buying cheaper disposable batteries. These will pay for them selves in the first 2 use's!

Nunca has probado unas pilas tan buenas como estas. De hecho duran tanto y sin perder potencia porque también son de 3,7 voltios en aparatos compatibles. Si las pones en aparatos normales dará 1,5 voltios constantes durante todo el tiempo y duran mucho más que una alcalina, es decir, son incluso mejores que las alcalinas, no pierden voltaje hasta que se gastan del todo. 50€ puede parecer caro, pero por ese precio tienes un cargador USB inteligente que te permite cargar las pilas de una en una o con diferentes cargas y cuando una de ellas esté cargada la deja de cargar mientras sigue cargando las demás.El único inconveniente que tienen es que el dispositivo te dirá siempre que están a tope porque siempre marcan 1,5v. Y cuando se agota la capacidad baja el voltaje en pocos minutos, así que no sabrás cuanto le queda hasta que no veas que el dispositivo no dice que están a tope, entonces sabes que quedan pocos minutos. Pero ese inconveniente está compensado sobradamente por sus grandes ventajas.No me cabe ninguna duda que si me hacen falta más pilas AA volveré a comprar estas por 50€

Kentli PH5 AA Lithium Batterien benötigen wir für unsere Stirnlampen mit 600 Lumen ( 4 Stck. )Bei max. Einstellung der Stirnlampe ist die Leistungsfähigkeit des Akku begrenzt , ca. 1,5 Std.Bei schwächerer Leistungseinstellung hält der Akku mehrere Tage .Mit einen digitalen Lith.-Ladegerät ist die Aufladezeit außerordentlich kurz.! ( mehrere Minuten !!! )Über die Standzeit der Akku kann ich noch keine Aussage treffen , da ich sie noch nicht so lang habe.

Product delivered in time and as described on amazon.Excellent product : these batteries have a large autonomy and are very useful in remote locations
