All batteries produce Direct current. there are no AC batteries. to charge a battery you need a DC Charger that produces a voltage that is slightly greater that the voltage of the battery.
Not all batteries are designed to be recharged but the ones used in cars and trucks have large lead/acid 12vdc batteries. In motorcycles and scooters they now use smaller sealed lead/acid batteries that are in the 6 to 10 amprere range.
These spaller battries should not use big amp chargers but should be slowly charged with what is called a trinkle charger that is usually less that 1 amp and take longer time to safely charge the cells. To fully charge the battery may take about 8 hours.
One may also charge a small battery by using jumper cables from an automobile. In all cases watch the polarity of your connections.
