So, it's my experience that batteries will oxidize and leak and stuff like that and I assume that the batteries in the VMUs or on the DC controller board are no exception. All the batteries in my DC VMUs date back to like 2000/2001... I haven't noticed any problems yet, but is this something I should look into replacing sometime soon? Are these batteries all ticking time bombs? I don't want to destroy my memory cards or DC through neglect...
