12.68v 12 hours after bulk and maintenance charge.Healthy battery?
I have an 110ah deep cycle marine battery and stupidly allowed it to go down to 11.88 volts under load. So I disconnected all devices and used my AC charger which did a bulk charge for a few hours at 13.5v thenswitched to maintenance charge for a remaining 3-4 hours. After disconnecting, I waited 12 hours before testing again with the multimeter and it reads 12.68v . Is this considered normal for a healthy battery, or does this mean its just not holding its charge very well?
Many thanks

That battery is excellent as a good battery should hold between 12.53 /12.68 v at rest.
