Having recently recieved my 1Ghz unit, after giving it the recommended 10 hour charge everything seems fine and all is working well. My Issue is that as i traded in my batch 1 unit sometime ago (July i think) to reduce the cost of acquiring the 1Ghz, i now have a secondary battery that has not been charged in 6 months (because i was in craig's stalled queue). Should i charge it again, or will it be discharged beyond usefulness by now?
