Capability

For many boating functions, capability will be measured in certainly one of two readings, relying upon the aim of the battery.

For beginning batteries, it’s all about instantaneous output, which is measured as Chilly Cranking Amps (CCA). So long as the beginning battery meets the CCA requirement of your outboard, it’ll carry out as wanted till it must be changed. There’s actually no have to spend more money on larger CCA batteries than what your outboard wants.

For dual-purpose and deep-cycle batteries, a battery’s amp hours can provide an excellent indication of its reserve. Whereas amp hours are literally a measure of how a lot cost goes into the battery throughout charging, it presents a relative quantity to check batteries of various sizes and kinds. For many trolling motors, batteries of 80- to 100-amp hours will present a full eight-hour day of use underneath regular circumstances. Preventing excessive winds and present can deplete batteries faster, chopping that utilization significantly.
