Deal: 1800 mAh iPhone backup battery for a measly $13

RichardSolo is selling its 1800mAh iPhone backup battery for $13 (delivered) through July 31.

I reviewed the 1800mAh battery pack here on The Apple Core back in November 2008:

It’s super-easy to use — just snap it on and it begins to charge either the original iPhone and the iPhone 3G instantly. It also has a unique latching mechanism that firmly connects the battery to the iPhone – a first in iPhone external batteries. A new (optional) support brace keeps the battery attached to the iPhone.

The new model is constructed of polycarbonate/plastic which makes it feel lighter than previous models which have an aluminum housing. Also new in the 1800 are two built-in lights; a white ultra-bright LED flashlight and a red laser pointer.

This best-selling backup battery (which originally sold for $69.95) is now just $5.98 plus $6.95 shipping. When you order two or more, the unit price drops to $5.09 each.

These are new in box, not refurbished and include the following accessories:
