Battery Replacement
Testing, replacement, and charging checks so your boat starts every time you head out

Batteries And Charging Systems
Our technicians test and replace starting and house batteries and check the cables, switches, and charging system that keep them working.
A battery that struggles after winter or dies on the water is not always the battery alone. Corroded terminals, loose cables, a failing charger, or a switch left on can drain a good battery, so we test the whole circuit before recommending a replacement.

Battery Questions
Slow starts, a battery that will not hold a charge, and electronics that dim or reset are the most common signs. A load test tells us for sure.
Yes. We check the onboard charger and the charging output from the engine, since a weak charging system can drain a new battery.
When two batteries are wired together and one has failed, replacing them as a pair is often the better choice. We will explain our recommendation before any work starts.
