Herein, how many amps does a 12 volt battery have?
A typical car battery with 12 volts rating has a capacity of 48 Ah. It means that when fully charged, the battery can deliver one amp for 48 hours, two amps for 24 hours and so on.
Secondly, is it better to charge a battery at 2 amps or 10 amps? It is best to slow charge the battery. Slow charging rates vary depending on the battery's type and capacity. However, when charging an automotive battery, 10 amps or less is considered a slow charge, while 20 amps or above is generally considered a fast charge.
Correspondingly, what should a 24v battery read?
The target voltage for a 24 volt charger for AGM or some flooded batteries is 2.4 to 2.45 volts per cell, which is 28.8 to 29.4 volts.
Is 24v better than 12v?
Other things being equal, that would cause losses on 24v to be half those on 12v. so a 24v system is always better than a 12v system – provided you can physically fit two batteries. The amount of energy in the batteries is amps x hours x volts. Consider a 12v 60 Ampere Hour battery.
