A 120Ah marine leisure battery earns its place on any boat where the electronics stay live after the engine stops. Because this one carries dual pole terminals, the starter draws from one pair while the wiring loom, instrument panel and cabin lighting run off the second, so a single case does the work of two without a split-charge setup. The 940 CCA rating gives it the punch to turn over a cold diesel, while the cyclic construction lets it take the slow, repeated discharge that a night at anchor puts through a domestic bank. Charging comes from the engine alternator underway. For coastal cruising in Ireland, where a boat may sit on a mooring for a fortnight between trips, a battery sized like this leaves headroom rather than running to the bottom of its capacity every outing.
