Sorry for the off-topic post... I just got a T68i to replace my beloved but dying T39m. Does anybody have any advice about charging the battery for the first/second/... time. The guy at the store said that the first time I should leave it plugged in for 16 hours in order for it to reach its optimized level of charge. He mentionned also something about the second and third time you recharge it, but I forgot what! Any tips appreciated! Alexandre
