Being generous that might be a guaranteed minimum, or maybe "1300 mWh" is a lie.
I've set the Cherrybomb on full beam with a freshly charged set, in theory it should last around 49h if it's 1300mWh.
I assume if a battery gives me at least 90 percent of rated capacity, that it good enough, that was my assumption before I read this. So I find it interesting that the rating on the battery is exactly 90 percent of the rating on the package. I do not recall ever seeing a rated number on the package that differs from the printing on the item inside the package.
If the hour run time rating is based on declining voltage and possibly declining amperage as the battery runs down, the light gets dimmer over time but, those dim hours that consumed less energy are counted too. The Li Ion AAA batteries put out a constant 1.5 volts and the light should stay bright the whole time until the battery is exhausted, thus no dim hours, thus runtime might be shorter than the math suggests.
