FAQ:
Q: How many amps does a 2 amp charger deliver?
A: This means that it can deliver 1 amp per 48 hours, or 2 amps in 24 hours, 8 amps in 6 hours, and so on. So a 2 amp charger will deliver 2 amp per hour to this “flat” battery, and if it requires 48 amps that in means it needs 24 hours to fully charge.
Q: How long does it take to charge a 10 amp battery?
A: A 10 amp charger, in comparison will take a little under five hours to fully charge the 48 amp battery. There are some that prefer a slow charge because fast charging can lead to overcharging and buckling of the battery plates.
Q: Which is the best charger for a car battery?
A: A word of advice: a 3-stage automatic charger that is rated at 12 volts / 10 amp is the best choice for charging automotive batteries. However, keep in mind some chargers rated at 10 amp do not actually constantly output that the whole 10 amps steadily during the whole charging cycle.
Q: How many amps do you need to charge a car battery?
A: The battery capacity and its type also plays a big role in calculating charge time. As for car batteries, it is a rule of thumb not to fast charge them using anything that exceeds 20 amps. Slow charging using 10 amp chargers or less is generally accepted to be better.
