Prolonged Shore Power

Mooneypaul · 11-12-2006, 01:06 PM

I recently took delivery of a new Adventurer 38J and in the manual it states that it is not recommended that the unit stay plugged into shore power for "prolonged periods". We intend to camp in Florida for 3 months and I was wondering what I should do? Should I disconnect the coach batts?

My manual says to hit the battery disconnect switch under those conditions.
If we are parked more than a week or so I do what they say.

My Vectra is connected to shore power for months at a time,but once a month I have a reminder come up on my computer telling me to start the generator and check the house batteries (water level).I installed the Flow-Rite Battery Quik-Fill kit,works perfectly.You will also have to charge the engine battery,I installed the Trik-L-Start,works perfect.

Hello mooneypaul. Commander11 here. Recently purchased a 2007 38j on the work horse. Haven't taken delivery yet(wednesday) but would be very interested in your comments/experiences to-date. Re- the subject of your thread.I think the battery disconnect switch should take care of your problem. Then your inverter/battery charger takes over vis a vis charging your batteries.No????

I suspect the issue is primarily the quality of the battery charger and its ability to float the batteries at a proper charge for long periods of time.

I replaced my stock converter/charger with this one. I also added the Charge Wizard, which has a mode select button and indicator light on it. This is a good system, and removes any concerns of cooking your batteries.

My Owners Manual says:
"We do not recommend leaving the shore-line plugged in continuously during storage periods because the batteries can lose electrolyte fluids.........."

So you need to check the batt fluid levels frequently, particularly in hot weather. I'm full-timing & always stay plugged in. But I chk those house batts min every two weeks.

Also, on my rig, the Aux Battery Switch has no effect on the house batts ("Off" does not disconnect the house batts) when plugged into shore power. With the sw selected to Off, the house batts will be disconnected when shore power is unplugged. Same with the Alternator; the house batts (& chassis batt) will charge while driving, regardless of Aux Batt Sw position.

Thank you, they are great suggestions.

Some chargers allow you set the charge rate to zero which stops the charging of the house batteries. The manual for the Dimensions unit in my coach notes this as well. If you set it to zero, then need to remember to reset it periodically to keep batteries charged. Some units also allow the max charge rate to be 5amps, 10 amps, etc.
