Because you (well, maybe not you, certainly not me, but perhaps some people) should be able to deduce the voltage from chemistry of the battery. So all LiIon LiMnO2 chemistry batteries have 3 V, LiFePO4 chemistry has 3.2 V.

Then you can just multiply the voltage by mAh and you have energy in mWh

The problem with this is two-fold. First - I shouldn't have to care about battery chemistry. Second - what if they're wired up in series [1]?

From personal experience, I've seen that laptop & mobile batteries list watt-hours as well. I'd prefer if that number was advertised instead.

[1]With two LiPo 3.7V 3Ah cells, you can have either 7.4V 3Ah or 3.7V 6Ah.
