What kind of battery charger is the best for the car?

Look for one with 30 amp charge an 5 or 10 amp charge with 6 an 12 volt option. 30 amp will get you started if batterys dead with about a 20 to 30 min charge. 5 to 10 amp can fully charge it in about 6 hours if you dont need the battery right away. You should find 1 about same price as one you looked at. Schrider is a tough brand charger.
