Macrumors received some photos showing what is claimed to be the battery of the upcoming iPad Mini. The photos show that the battery runs at 3.72 volts, offering 16.7 Whr of energy on 4490 mAh of charge. It also shows the model number “A1445” and Apple part number “616-0641”. Macrumors can not confirm the authenticity of the photos, but they are pretty sure they are real.

The 16.7 watt-hour capacity for the iPad mini battery unsurprisingly places the device between the iPhone 5 at 5.45 watt-hours and the third-generation full-size iPad at 42.5 watt-hours. Given that the iPad mini has been said to be based more on the iPad 2 and lack a Retina display, the iPad mini’s battery may be more appropriately compared to the 25 watt-hour battery of the iPad 2.

According to the latest rumors the iPad Mini will be announced on October 23.
