What is ampere hour (A.H.) capacity?

0

A. Product of amps multiplied by time. It refers to the volume of electricity that can be drawn from a battery. Other factors (refers to number of cells in battery, truck resistance, truck motor, rate of discharge, etc.) being equal, higher ampere hour capacity batteries will run a truck longer than those with lower ampere hour capacities. A.H. capacity of a battery dependes on the type, number, and size of plates per cell. • Q. What is meant by capacity “at the six-hour rate”? A. The amount of electricity which a battery yields varies with the rate at which the electricity is taken out. For example, an 18 E85-17 Ironclad battery is rated at 680 ampere hours at the six-hour rate. This means that this battery will deliver a total of 680 ampere hours if it is discharged at a continuous rate of 113 amperes per hour for six hours. However, if this same battery is discharged at a lower rate, such as 90.5 amperes per hour for 8 hours, it will deliver a total of 724 ampere hours. The lower th
