Choosing The Right Batteries For Your Boat

Between the engines, helm displays, trolling motors, live wells, sound systems, lights, and other gadgets, marine batteries are the unsung heroes of sailing . Your boat’s batteries serve two primary functions: starting engines and running accessories. Some batteries are built for one function while others can do both, so it’s important to understand your marine battery basics.

Boat Batteries 101

Because modern boats have increasingly complex power demands, it’s important to understand your vessel’s needs. consistent with Mike Gursky, District Sale Manager for Taylor & Crowe Battery, one battery type typically won’t cut it. He breaks down the marine battery types like this:


These batteries are often used for both starting and cycling, making them an honest solution for little powerboats that use one battery or sailboats that has got to use two identical batteries interchangeably.


Unlike starting batteries, deep cycle batteries are designed to supply reliable power over longer periods of your time . They’re used for accessories like trolling motors, electronics, and anything that relies solely on battery power.


These batteries are used for starting engines only. They’re designed to deliver a fast burst of power and are generally maintenance-free.

Whether you’re a first-time boat buyer or advanced boater, Mike’s advice is simple:

“Make sure you specify the right batteries for the way you're getting to use your boat. Starting batteries shouldn’t be utilized in cycling applications. Deep cycle batteries should be used when the battery is solely powering the vessel and may be utilized in starting situations as long because the required engine starting cold cranking amps are being met. Dual-purpose batteries are often utilized in both cycling and starting applications.”
