Q: What are the 10-hour and 20-hour rates of VRLA Battery?

A: The 20-hour rate is just an index that is used in the battery industry to compare batteries of different types and sizes. The 20-hour rate is the amount of Ahs the battery will deliver during a 20-hour discharge. The capacity of a battery, in Ahs, is a dynamic number that is dependent on the discharge current. For example, a battery that is discharged at 10A will give you more capacity than a battery that is discharged at 20A. With the 20-hr rate, the battery is able to deliver more Ahs than with the 10-hr rate. Because the 20-hr rate uses a much lower discharge current than the 10-hr rate. Both rates are used as baselines in different parts of the world. Either rate, however, will give you the same view of a battery. A higher capacity battery will have higher 5 and 10 hour rates than a battery with lower capacity.
