Just one other wee silly question regarding the Argus GT... When charging, the two batteries were always within one or two percent of each other. Couple of days ago, I recently removed them to do a sort of 'hard restart' as I couldn't get the thing out of chip ID mode (doh, I know!). Now, since re-inserting the batteries, they're charging 7 or 8 percent apart: one at 71 and the other at 64. Actually just looked again, one is at 66 and the other at 72 now. No big deal, right? It's just that bloody OCD of mine kicking in again
