can anyone confirm if the 600exrt is a power hungry device? i recently bought a couple and my rayovac lithium 4.0 and regular costo AA batteries couldnt even power the device consistently. the freshly charged rayovacs would give out in a couple of flash recycles and the regular AA would also shut off after awhile.
maybe im missing something here. perhaps the only battery to power it reliably is the sanyo eneloop XX? or does anyone have any suggestions thanks!
