I was wondering about the PCC that came with my Joye 510. When storing a battery in it, the lid only closes when it's fully seated in the charging dock. Now I remember with the Blu charging pack if you left the batt screwed in, it'd drain the pack. Is that the case with this? I'd really like to just be able to leave the batt in the PCC when I'm out and about, without having to worry about the PCC losing its charge. Anyone got any light they can shed on this for me? Thanks in advance!
