@FrancisKelch My question would be why?
From Mooch's review of the battery:
If it works just like a HG2, why not stick with a proven brand such as LG, and not a manufacturer that puts a dangerously misleading rating on a battery? From the link you posted they are $18.95/pair and at the bottom of the page you can get LG2s for 15.95/pair.
They do have a nice looking wrapper though. I personally will stick to the major manufacturers such as Samsung, Sony, and LG personally.
If you are going to spend over $9.00 a battery, I would suggest the new VTC6. It seems to edge all of the 3000mAh batteries out at this time.
