My question is.....is it safe to place a small battery minder which will be powered via an extension chord....directly in the battery compartment.
My 2001 Winnebago DOES NOT have a system that charges the Engine Battery when plugged into shore power. The Coach batteries DO have an internal charging system as well as a solar panel.
SO, I purchased a Battery Tender from Harbor Freight (appx $4.99 - 5.99) and attached it to my Engine Battery. Since my batteries are under a removable entry step, I just ran the wire from the battery compartment along the wall behind the recliner to the nearest 110v outlet near the passenger seat.
Result: I have been doing this for years and it keeps my engine battery at ~13.5v all of the time. My coach batteries are charged via the inverter and are also maintained at ~13.5v.
I DO check the acid level in all batteries every few months and never had a problem with overheating or loss of fluid.
For me, this was an easy and very functional fix for ensuring that my batteries are kept at maximum charge all of the time.
