The right battery for your boat

Most boats use one or more of three battery types: starting batteries that deliver a burst of power to crank the engine, deep-cycle batteries that run electronics and accessories over time, and dual-purpose batteries that do a bit of both. We'll help you choose the right battery for your engine and the way you use your boat.

​

Signs it's time for a new battery

The engine cranks slowly or not at all, the battery won't hold a charge between trips, electronics dim or cut out when the engine starts, or you see corrosion, swelling or damage on the case or terminals.

​

Battery testing with every service

Our 100-hour and 300-hour services include inspecting and testing your batteries, so a weak battery gets caught at the shop instead of at the launch ramp. W.O.T. Marine is a Mercury Authorized Service Center in Vista, CA, serving North County San Diego, greater San Diego County and the Inland Empire.
