The location of the battery on the 2018 Ram ProMaster Cargo Van is on the driver side of the vehicle and under the front driver side floorboard. If the vehicle just needs a jumpstart You can jump the vehicle from under the hood without needing access to the battery. The size of the battery on the vehicle is Group Size 49, 850 CCA. The battery should last anywhere froM3 to 5 years before it needs to be replaced. The battery won't last as long in regions with high heat and humidity. It should be load tested every 2 years to see how much life is left in it. If a new battery is needed, a new one costs anywhere from $150 to $280 depending on the brand.
