San Diego waterways
San Diego Bay curves from Point Loma past downtown and Coronado, with marinas at Shelter Island, Harbor Island and the downtown waterfront. Mission Bay, north of downtown, is a big aquatic park with ski areas and calm coves. The Point Loma kelp beds lie just offshore, and the Coronado Islands, across the border in Mexico, are a short run south.
Sailing is popular on the bay, and the Navy’s ships share the harbor with recreational boats. Many boats live in slips on shore power, so a smart charger set for your battery chemistry is important.
Typical boats around San Diego
Yellowtail, yellowfin and bluefin tuna, calico bass and halibut draw anglers, and the sportfishing landings on Point Loma run day trips and long-range trips into Mexican waters. Fishing the Coronado Islands requires Mexican permits.
Recommended setups
Offshore center consoles
Offshore boats depend on their batteries more than any other boat on San Diego Bay: 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
If your sailboat on San Diego Bay uses a lot of power at anchor, lithium is worth a look. It provides more usable capacity per pound and accepts charge faster. Before you switch, check that your alternator, charger and solar controller support lithium.
Bay boats, skiffs and shallow-water rigs
Most bay boats on San Diego Bay 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.
Keeping batteries healthy in California
Year-round use means batteries never get a rest. Keep them charged, and check terminals for salt corrosion.
Many Southern California boats sit in slips for long periods. A maintenance charger or lithium battery helps.
Southern California’s mild climate means year-round boating. Salt air is the main threat to batteries, so keep terminals clean and coated.

San Diego shipping FAQ
My boat stays in the water all year in San Diego. What should I do about batteries?
Keep the boat on shore power with a smart charger set for your battery chemistry, or use a battery switch to isolate the batteries between trips. Check terminals for corrosion every few months, and test the batteries before the busy season. If you leave the boat unplugged, a lithium battery’s low self-discharge helps it stay ready.
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.
Do you have a store or installer in San Diego?
No. We ship to San Diego from our store. Professional installation is a flat $99 per battery ($249 for a 24V or 36V lithium bank) anywhere from Venice to Gainesville, with no travel charge.
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.
