[C320-list] Battery Issues

[Tim]

Hello All,
   
  Lately my #2 battery is very low after my boat has sat for 3-5 days. It takes a charge from running the engine and I have checked the water level with only the middle cell needing a bit of water. Should I be considering a new battery, my boat is a 99 Hull# 603 and I'm almost certain these are the orginals.
   
  The only thing new electrically is I have added a radio which had a constant power connection to the battery for the clock and radio memory. I have since disconnected that to see if that was the culprit but I suspect not.
   
  thanks...
