Battery Charging from shore power

[Jason687]

Have recently acquired a 2011 Montana 3150RL. No solar on rig. Need to replace a dead battery. First thought is to understand the charging system when connected to shore power. From the factory, did this rig use a multi stage charger that includes trickle charging once a full charge is reached, or will I burn out the battery if I leave shore power connected during winter storage?



Are there any useful after market upgrades other owners have made to the charging system to improve effectiveness?


Thanks in advance for comments/help in understanding.
