So glad to share we release a new rechargeable 1.5V AA CLR 2700mAh/4300mWh Battery. It has 2700mAh high capacity, Providing long-lasting performance in standard and cellular cameras. This new battery has the 1.5V constant output plus gradually linear discharge curve. The charge level of this battery would decrease slowly and not suddenly. Then it prevents sudden shutdowns and gives ample time to replace the batteries, ensuring uninterrupted outdoor photography.
Please check more details online:
So if I get it right: these are just like the 1.2V Ni-MH rechargeable batteries we all know. But with a high(er) capacity. What about the number of cycles they are good for?
And a higher voltage! They are intended for devices that struggle with 1.2V from NiMH batteries.
The linked ad says 1200 cycles…
It also says:
“Reduce global warming by 30%” 
It’s not clear what charging algorithm these things need.
Constant 5V input.
Have you considered making a combined storage case/ charger so people don’t need to go out and buy yet another different battery charger?
I’ve a got different brand’s lithium 1.5V AA rechargeable battery set and that’s what they do. It’s a great idea and makes them easier to sell.
Problem with leaving cells in an unpowered charger is always the drain. Not sure what the technical term is, back current?
I’m not convinced these are superior to the USB -C cells available from Xtar (though, from a safety perspective, the thought of using two mis-matched Lithiums because one only has a single USB-C cable on them at the time, terrifies me).
helo Xtar! i am looking for 1.5v AA li-ion rechargables; i want to ask if this 2700mah batteries will work on Turbo in Acebeam tac 2AA flashlight? coz i am thinking because has big capacity , because of that has lower continous discharge? thanks! - i am looking on many batteries on Ali but i can not decide; so i am asking coz i buyed 2 ‘‘Vartha ultra lithium’’ non-rechargables but that not even jumps up to Turbo [meanwhile a simple Duracell alkaline does - or maybe that Varta i buyed is fake i dont know]
Thanks for your comment. The Max Discharge Current of xtar 1.5V AA CLR 2700mAh/4300mWh Li-ion battery is 2.5A. May I know your Acebeam tac 2AA flashlight’s requirements for the batteries’ voltage and current?
For this xtar battey, if the discharge current exceeds 2.5A, the protection system will kick in to safeguard the battery from damage. So for devices that demand continuous current exceeding 2.5A, using the 1.5V Li-ion batteries might not be very suitable due to the battery’s protection systems.
