Hey all.. had a quick question regarding the NH-14WM Stamina batteries I bought myself an MZ-RH10, and so far the unit has been awesome! The only thing I'm noticing is that the gumstick batteries that I've got for it, seem to be very weak. I received one that came with the unit, and I've also purchased 2 more. I don't have a charger for them, so I've just been putting them into the MD and charging through the power adapter and serial cable. However, when I leave the battery to charge in this method for what seems like days, and I go to play a disc, the battery indicator is full until the disc starts up and locates the first track. As SOON as the screen comes up with name, album etc, the bar goes down to half full.. almost immediately. It does this with all three batteries. Which leads me to ask, is it possible these batteries aren't getting charged properly? or could it be that they just suck a$$ and can't hold a charge at all. I have to say I'm pretty dissappointed, cuz having to connect up the external AA battery makes the unit a fair amount larger, and bulkier. I'd much rather have the unit just run off of the gumstick battery, but it seems like its not going to happen. Anyone else have this experience? Is there any way around this?? Thanks for any info!!!
