Marine Batteries Shipped to Falmouth, MA

Falmouth, on the southwest corner of Cape Cod, sits between Vineyard Sound and Buzzards Bay, and its village of Woods Hole is home to world-famous ocean science institutions and the ferry to Martha’s Vineyard.

We don’t have a shop in Falmouth. Marine Battery Source is an online store, and we ship to Falmouth and the rest of Massachusetts. Lithium batteries over $150 ship free by curbside truck freight to the lower 48. Chargers and accessories ship free when your cart reaches $150. Lead-acid and AGM batteries ship free by curbside truck freight too.

Where Falmouth boaters launch and cruise

Falmouth Harbor and Falmouth Inner Harbor are lined with marinas, and Waquoit Bay lies to the east. The Woods Hole passage, between Buzzards Bay and Vineyard Sound, has some of the strongest currents on the coast.

Most boats are hauled for winter. Woods Hole is home to the Woods Hole Oceanographic Institution, the Marine Biological Laboratory and NOAA’s fisheries science center, and the Steamship Authority ferries to Martha’s Vineyard leave from its harbor. Fall brings bonito and false albacore close to shore, and anglers run fast between schools, which is hard on loosely mounted batteries. Salt spray is constant, so rinse and coat terminals often, and charge batteries fully before winter storage.

Boats and fishing in Falmouth

Striped bass, bluefish, bonito, false albacore, fluke, scup and black sea bass are fished. Sailboats, center consoles and cruisers fill the harbors.

Batteries that fit Falmouth boats

Center consoles and offshore boats

Offshore boats depend on their batteries more than any other boat on Falmouth Harbor: radar, sonar, chartplotters, livewells and VHF all draw power while drifting over a ledge. Size your house battery for a full day of electronics with the engines off, and keep it isolated from the cranking batteries with a switch or combiner. A multi-bank onboard charger keeps every battery topped up at the dock.

Sailboats and cruisers

Sailboats and cruisers in Falmouth rely on a house bank for lights, refrigeration, instruments and an autopilot, plus a starting battery for the auxiliary engine. A bank of 6V golf-cart batteries wired in series is a traditional choice; lithium banks like the EPOCH 12V 300Ah or Battle Born 100Ah give more usable capacity and recharge faster from solar or the engine.

Bay boats and flats skiffs

Most bay boats on Falmouth Harbor run a 24V or 36V bow-mount trolling motor plus a separate cranking battery for the outboard. A 36V lithium bank, such as a single EPOCH 36V or Interstate 36V battery, replaces three Group 27 or 31 lead-acid batteries and drops well over 100 pounds from the stern, which helps a skiff float shallower. Keep the cranking battery separate so a long day on the trolling motor never leaves you unable to start.

Seasons and storage

Strong currents mean boats need reliable cranking batteries.

New England and Long Island boats are usually hauled for winter. Charge batteries fully before storage, and keep lead-acid batteries on a maintainer or remove them. A discharged lead-acid battery can freeze and crack.

The boating season is short, so it pays to have batteries ready in spring. Test them before launch, and replace any that won’t hold a charge.

Frequently asked questions

How do I keep salt corrosion off my batteries in Falmouth?

Rinse the battery area with fresh water after salty trips, keep terminals tight and coated with a marine terminal protectant, and check cables for green or white buildup every few weeks. Sealed AGM and lithium batteries don’t vent acid, so they keep compartments cleaner than flooded batteries.

Is lithium shipping really free to Falmouth?

Yes. Lithium batteries over $150 ship free by curbside truck freight to addresses in the lower 48 states, including Falmouth.

How do lead-acid batteries ship?

Lead-acid and AGM batteries ship free by curbside truck freight to the lower 48, the same as lithium.

Do chargers and accessories ship free?

Chargers, accessories and lithium batteries of $150 or less ship free when your cart subtotal is $150 or more. Otherwise a flat shipping rate applies, shown at checkout.
