I have a Samsung VPD10 camcorder (bought 3 years back). For past few months I observed that the battery gets exhausted only after 15 minutes. Earilier it used to last 1.2 hours. I have two batteries (both purchased 3 years ago) and both are having same problem. Is it that I need a new battery or the charging mechansim of the camcorder is malfunctioning? Thanks for any help.
