[C320-list] Battery Help / Confused ?

[BAdams3491 at aol.com]

Joe,
 
I got that information from one of my 12v electrical books...don't know if  
it was from a boat book or RV book...but the information should apply to  both. 
 Here's the chart:
 
12.6 or more is 100% state of charge.
12.4 to 12.6 is 75% to 100%.
12.2 to 12.4 is 50% to 75%.
12.0 to 12.2 is 25% to 50%.
11.8 to 12.0 is 0% to 25%.
Below 11.8 is 0%

Why do you say the battery is 75% discharged.?
A 12 volt  battery at rest I thought usually displays 12.2 - 12.4 volts
when not being  charged, while being chrarged it is usually 14 + volts
and shorly after  being charged   13+ volts and will eventually
stabalize to 12.2 -  12.4.

This is my first experience with deep cycle batteries so if I am  wrong
than let me know.

Thanks

Joe

The  batteries are not orginals one was replced in 2005 and one in 2006,
The  chrger is the original a Flyback Promariner that makes a lot of  noise,
which might need to be replaced.
