How is Ah Measured in Duralast Marine Batteries?
Ah is measured in Duralast marine batteries by evaluating the total capacity of the battery to deliver a specific current over time. The capacity is usually expressed in amp-hours (Ah). To determine the Ah rating, manufacturers conduct tests under controlled conditions. They discharge the battery at a constant current, measuring how long it can sustain that current before the voltage drops to a predefined cutoff level. This duration, when multiplied by the discharge current, gives the total amp-hours. For example, if a battery can discharge at 10 amps for 100 hours, its capacity is measured at 1000 Ah. This measurement helps users understand how long the battery can power devices before needing a recharge.
