Reducing Battery Compartment Ventilation Area
I have debated about reducing the size of the vent area on the top of the battery compartment on our '06 since I replaced the wet cell batteries with Lifeline AGMs about 3 years ago. Just don't see the need for the huge hole in the top of the compartment that drives a lot of dust and road grit into the battery compartment from the engine area. Figure it would keep me from dusting the battery compartment as often as i do to keep it looking new.
I have seen a couple Alpines where the owners have reduced the size of this vent opening after they replace their wet cell batteries, but don't remember the size they felt comfortable reducing the hole. I don't have the coach near me right now but I think the hole is about 8" x 16". It also seems to me the ones I have seen reduced are down to about 3" x 5" or so.
I'm down to a small list of to-do's on the coach and wondered, those of you who have reduced the area with some sheet metal/screen, or those of you who have some electrical background -- how small do you think this vent hole could go to without any problems, with AGM house batteries and sealed engine batteries?
