New Li-Ion 1.5v AA batteries from Xtar.
Until now, Li-Ion AA batteries have maintained a steady voltage then died instantly at the end of the discharge, like the Xtar 2500mAh graph shows.
Now Xtar have come up with 3 more gradual ends to the discharge. The 3000mAh has a discharge curve similar to NiMh AA, but maintaining a higher voltage. The 2700mAh maintains a steady voltage, but then tails off more gradually at the end. The 2450mAh also maintains a steady voltage and drops off suddenly at the end, but to a lower voltage which is maintained for a short while before discharging completely.
The 3000mAh and 2450mAh charge directly by mini usb-c, the 2700mAh need a charger.

That’s pretty cool they offer such options. I wonder if they all use the same base underlying 14430 cell, and if it’s the circuit causing the different capacities.

Brilliant graphs, thanks! I was pondering the difference between these just yesterday!
Sorry if I missed it, what current did you discharge these at?
