Assuming that someone with the original run of the scanner (small battery) didn't complete their registration properly yet, how exactly would you guys know to even ship the larger battery out to them at this point?
If they have registered w/a valid email address, we sent several emails advising the process (if they had not already completed the process). In a week or so (after the initial demand volume drops) we'll repeat that email.
Some people intentionally or inadvertently use invalid email addresses. We cannot contact them (for reasons which I hope are self-evident).
