MacRumors has obtained photos of what is reported to be the internal battery for the upcoming iPad mini. As indicated by the battery's marking of 3.72 volts, the battery life on the 7.85-inch iPad is expected to be between an iPhone and fully sized new iPad, 16.7 Whr of juice on 4490 mAh of charge. As a disclaimer, we can't yet authenticate if the leaked part is legitimately from Apple, but based on other Apple-designed batteries, it has the familiar markings of past and current products. The battery is still in regulatory limbo, and is subject to be changed if needed.

The iPad mini is rumored to be unveiled on October 23rd. How's that for doubling down on secrecy?
