7.2V/1800mAh Li-Ion L-Series Digital Camcorder Battery - Sony InfoLithium style, in store only for $3. Link to check availability: http://www.radioshack.com/product/index ... Id=2036250

A few more batteries are on clearance, but are harder to find a store that carries them, and only one is on par with the $3 one. Search for Li-Ion and sort by price to see.

I thought I'd pass it along for those looking for a battery for their portables.

What would be the best way to charge 2 of these in parallel? The only thing that worries me is that the review says these don't last very long.

I found these on there http://www.radioshack.com/product/index ... Id=3125812 anyone know about it??
