So I'm in ratshack today and they had a Lenmar 9V DVD LI-Ion battery for five bucks. Granted it was a 2600 mAh but still for five bucks you could get a big pile of them ;D
Whoops sorry it was a typo at our local store
was it a typo:
I was there, they had non but they looked it up and found this:

49.99. A bit high.
I just bought some of those on EBAY. I thought they were the same as my old batteries at 5400mah, but they came and they were 2600mah. I paid $19.99.
