If the van is in a garage or dry place you can take the charger to the van,disconnect both leads from battery first then charge it,if not then there will be a bar across the top holding it down by 2 nuts loosen them after FIRST disconnecting bat leads and wiggle it out,OR there is a plate at the front bottom of bat that you loosen with a 1/2in AF socket probably and extention bar.How big is your charger(its on the front ie 5amps-10 amps divide that by the size of your bat,should be about 75amp that tells you the trickle charge time from completly flat.ie 75-5 =15hours, 75-10=7.5hours.Why dont you bump start it?
