What is amperage in a golf cart battery?
Well, Amperage in a golf cart is like the gas tank in your car. It will determine how far you can travel on a single charge in an electric Golf Car. The more amperage in a battery pack, the further you can drive before having to charge. Click here to learn how to determine the age of golf cart batteries.
How do you measure RV battery storage capacity?
Amp Hours are the most useful and most common way to measure RV battery storage capacity. It’s easiest to think of Amp Hours (AH) as units of electricity in a battery ‘gas tank’. 1 amp hour is the amount of power it takes to run a 1 amp electrical draw for 1 hour. For example: An LED lightbulb may use 0.5 AH.
How many miles per round on a golf battery?

How do you calculate amp-hours on a RV battery?
As an example, if you have a 12V battery for your RV, and your device is rated for 100Ah, you'll need to multiply the amp hours by the volts: 100Ah x 12V = 1200Wh. To showcase how amp-hours does not equal energy, you could get the same 1200 watt-hours from a 24V battery. You'd multiply: 50Ah x 24V = 1200Wh.
How do I know how many amp-hours a battery has?
Calculating AH Multiply the battery's current (as measured through the resistor) by the time taken for the voltage to decrease to 12 volts to determine the rating for a half-charge. Multiply this number by two to find your battery's true AH rating.
