Battery discharge time depending upon load

Peukert''s capacity is the capacity of the battery measured at 1 amp discharge rate. Batteries are rarely specified with Peukert capacity. Battery manufacturers rate capacity of their batteries at very low rates of discharge, as they last longer and get higher readings that way. This is known as the "hour" rate, for example 100Ahrs at 10 hours.
