Batteries not holding charges
We have been having trouble keeping a charge on our house batteries. I have a Coacmen Freelander 29 QB. With 2 grp 24 deep cycle batteries we have to charge 2 to 3 times a day. This seems unreasonabl...

"One hour of charge is only going to show a surface charge voltage which is not the true state of charge"
It happened to me! I trusted the lights on the monitor panel but those lights greatly exaggerate the battery charge until a few hours after charging ends. And damage to the batteries results because they are not designed to be used below half charge (12 volts measured 4 hours after charging).
With little use of the batteries and LED lights, many of us manage with just charging from the engine as we drive for an hour or so per day. But this risks going below half charge and damaging the batteries, particularly in cold weather when the furnace is used a bit in the morning.
