battery charging

we found that campin connected to the shoreline - well the battery still ran down.
so we bought a little Trick-L-start thing and since then (2006) the battery starts the motorhome.
over winter we used to disconnect the MH batteries from the MH and use a Ctek to maintain the batteries. all 3 joined in parralel.

now we store it where we can leave the MH plugged in all winter in southern BC mild climate (usually).
then we read in the manual...NOTE: We do not recommend leaving the
shoreline plugged in continuously during
storage periods because the batteries
can lose electrolytic fluids and become
damaged from continuous charging
without periodic use or maintenance.
We recommend following regular battery
inspection and maintenance, especially
in cold weather.

any ideas? what is the worst that can happen to the new this year batteries?
the deep cell are maintainable the starter is no maintenance.
thanks all
  • We always boondock. Never plug in, never bring the generator. A 100 watt solar panel and charge controller keep the batteries over 80% charge all the time in summer here in sunny northern Alberta. I have the house batteries and engine battery connected so It is also kept charged. We have all LED lights, no TV and the microwave oven serves as a bread box.

    We just had a week at 20 below zero C and a foot of snow. The snow on the solar panel put it out of production, and the engine parasytic current draw discharged the engine battery well below 50%. I’ve got the smart charger on it now and am hoping it isn’t damaged too badly.
