When I winterized our 1975 Itaska RV this past fall I got to thinking about the two new HD deep cycle batteries in it. Can one of these be used in my 1995 E150 5.8L Tuscany Conversion Van as a replacement battery? I think I heard somewhere that the deep cycle batteries don't work well as the primary battery in automobiles. Thoughts and advice very appreciated. Thanks.

 

this would be best in the general auto forum.

 

Sorry. Thanks!
