There is a little variation because of chemistry and design, but expect 12.7 +/- 0.1V. AGM batteries are usually 12.8V at 100%, resting. ]]> Mon, 07 Dec 2020 22:44:20 +0000 http://www.rpod-owners.com/forum_posts.asp?TID=14268&PID=138787#138787 12volt deepcell battery readout on multimetre : When boondocking we change ours... http://www.rpod-owners.com/forum_posts.asp?TID=14268&PID=138750#138750 Author: jato

When boondocking we change ours out at 12.2 v. or 60% S.O.C. Since winterizing our 177, batteries were pulled and moved to our unheated garage on the concrete floor. Both batteries got a 24 - 30 hour 2 amp trickle charge on October 24 here in northern Michigan. Just checked them yesterday, 6 weeks after receiving the charge; they read 12.64 v and 12.61 v respectively. Not too bad for a pair of nearly 10 year old 12 volt Interstate, group size 24, deep cycles.

This should be close. But, you have to allow the battery to recover to its open circuit voltage (no charging or discharging) for at least 30 minutes before measuring it. Unless in an emergency, its best not to go below about 50% state of charge (around 12V) if you want to get long life out of your batteries.

What should a deep cell 12volt battery read on a multimetre if fully charged and how low should you let it get?
