How many of you are looking for maximum running time on your scanner's 'AA' batteries? I highly recommend these! They are sold at most camera shops for the high demands of digital cameras. They're also all over Ebay. They're normally sold in 4 & 8 packs. There is a seller on Ebay that sells the as single cells. However, the sealed bubble packs offer some assurance that they are not used.
I would not recommend charging these in the scanner using the 5v USB charging. Instead, invest in a professional battery charger such as Powerex Maha chargers. My personal favorite charger:
MH-C801D Offers rapid charge, soft charge, and conditioning.
MH-C801D - Maha Energy
Panasonic Eneloop Pro AA 2550mAh Ni-MH PreCharged 4 Pack Rechargeable Batteries
