Mobile Marine Battery Replacement in Dunedin, FL
Dunedin is a sailing and paddling town as much as a fishing town. The downtown marina is lined with sailboats and small cruisers, and the causeway out to Honeymoon Island is a favorite spot to put in a skiff or kayak.
We install batteries in Dunedin at your dock, the ramp or your driveway. Order online or text us. Installation is a flat $99 per battery ($249 for a 24V or 36V lithium bank); add it on the product page when you order. On lead-acid and AGM batteries, the $18 core charge is waived when you book installation and we take your old battery with us.
Not sure what fits? Browse lithium, trolling motor or cranking batteries, or text us a photo of your current battery.
On the water in Dunedin
The Dunedin Marina sits at the foot of Main Street on St. Joseph Sound. To the north, the Dunedin Causeway runs out to Honeymoon Island State Park, and across Hurricane Pass is Caladesi Island, one of the most visited boat-in beaches on the coast. St. Joseph Sound is shallow, with grass flats and sandbars that reward a boat with a trolling motor or a push pole.
What people fish for and run around Dunedin
The sound is known for redfish and trout on the grass, snook along the island beaches in summer, and cobia that cruise the flats in spring. Shallow-draft bay boats and flats skiffs are common, along with sailboats that need house power for lights, instruments and an autopilot. Kayak anglers on the causeway often run small lithium batteries for fish finders.
Keeping batteries healthy in Dunedin
Sailboats in the Dunedin Marina tend to sit at the dock between weekend trips, often on shore power. Old flooded house batteries that have been float-charged for years are a common reason for a replacement call.
Florida’s Gulf coast is hard on batteries for two reasons: heat and salt. Battery life drops quickly when a lead-acid battery sits above 90°F, and salt air corrodes terminals and cables. Sealed AGM and lithium batteries resist both better than flooded batteries, and none of them need water topping.
For Pinellas boats, sealed AGM or lithium batteries are worth the upgrade if your battery lives aboard on a lift or in a slip. Keep terminals coated, use a battery switch, and give lead-acid batteries a full charge after short sandbar trips that never let the engine top them up.
Battery types and sizes for Dunedin
Bay boats, skiffs and shallow-water rigs
Most bay boats on St. Joseph Sound 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.
Kayaks, canoes and jon boats
Kayak anglers on St. Joseph Sound usually need a small 12V battery for a fish finder or a light. Lithium batteries in the 10Ah to 30Ah range are light enough to carry and last a full morning. For a kayak trolling motor, step up to a 12V 50Ah lithium battery.
Sailboats and cruising boats
Many sailboat owners around Hurricane Pass stay with AGM or flooded batteries for simplicity and cost. Whichever you choose, keep the house bank and starting battery separate, and replace all batteries in a bank at the same time.
