[C320-list] charging

[Darrell]

I recently replaced my starter battery and house bank. I have been 
monitoring the float voltage from my charger and it is up at 13.8 and 13.9 
volts. This seems a little high to me from what I have read. Otherwise my 
stock charger from 1994 appears to work fine. I typically leave the charger 
on while I am not at the boat often a week at a time with the fridge 
running. So I don't damage my batteries I am considering the following
Replace the charger ($300-$400)
or put a $10 timer in line before the charger which turns it of and on every 
4 hours or so
Any advice would be appreciated,
