Newbie with battery question
After the first quick shakedown trip we parked the trailer, unplugged elec, etc. and left. Now it's been a couple of months. Didn't realize about the phantom draw against the battery but I do no...

Not sure why people feel the need to keep batteries hooked up and charging all the time but its not needed. A couple of my batteries have been left in the boat hooked up all winter long and have still showed 12.2 volts in the spring.
Here's why:
12.2 volts is approximately 50% discharged.
Batteries left sitting like that will age faster due to sulfation.
It is not AS much of a problem with deep cycles though.
And is almost no problem at all with AGMs as their rate of discharge is much lower.
Summary: Despite what you believe, if you have any variety of conventional lead-acid wet cell batteries it really is important to keep them fully charged.....or very near to full.
