Batteries

Some basic info including energy density and discharge curves for various types of batteries can be found [here].

Datasheets for Duracell OEM batteries [here]

Types:

• NiMH
• LiPo
• alkaline
• etc.

Check out how for the [MX 1300 D cell] the delivered energy becomes exponentially less as the power drain increases. e.g at 250mW you get ~15Wh, at 2000mW you get ~2.2Wh.
