How To Calculate Amp Hours. 1534Wh 252V 609Ah. To calculate amp-hours from watt-hours we need to rearrange this equation to.
Watt-hours watts hours efficiency 1250 085 1470 watt-hours. The following formula us used to calculate a battery capacity in amp-hours. In the example above a 1425 watt coffee maker uses 119 amps of battery power per hour.
They use the coffee maker 15 minutes per day so they are using 35 amp-hours of the 100 amp-hours.
Simply fill in two of the blank boxes below and click Calculate to convert amps. However if you only use that 100Ah battery for half an hour it can give 200A during that 30-minute draw if the battery operates at 100 efficiency. Amp-hours at 12 volts watt-hours 12 volts 1470 12 1225 amp-hours. Calculating the amount of energy stored in a battery will use a different formula than a solar battery bank calculator.
