    Absolutely agree with the fact that mAh should never have been used as a measurement of battery capacity, but increasing the voltage (while keeping the same actual capacity in Wh) makes the mAh rating lower, not higher.

    1 Wh 1 V battery can provide 1 A (1000 mA) for an hour (1 V * 1 A = 1 W, 1 Wh / 1 W = 1 h) - that would be 1000 mAh.

    1 Wh 2 V battery can only provide 1 A for half an hour (2 V * 1 A = 2 W, 1 Wh / 2 W = 0.5 h), and that gives you only 500 mA.
