To assess the performance of a battery under high current draw, a crucial step involves calculating half of its Cold Cranking Amps (CCA) rating. This calculation serves as the basis for the subsequent load test.

At the precise moment the 15-second mark is reached, it's imperative to pause and measure the battery's voltage output. This reading is indicative of the battery's ability to maintain a stable voltage under heavy demand.

The voltage measurement should be taken immediately before releasing the load from the battery. This ensures that the reading captures the battery's performance under the full stress of the test.

Let's illustrate this process with an example. Suppose the battery in question has a CCA rating of 700. To determine its response under stress, we divide this value by two, resulting in a test load of 350 amps.

The next step involves applying this calculated load directly to the battery for a precise duration of 15 seconds. This timed exposure mimics the battery's operation during engine startup, where a surge of power is required.
