Marine & RV Battery Solution

Reliable starting and lasting onboard power for every journey on water or road.

Power for the Journey—and Everything Onboard

When a boat leaves the marina or an RV travels beyond the next hookup, battery performance shapes both mobility and life onboard. In North America, fishing boats, powerboats, motorhomes and travel trailers often combine strong starting demands with growing loads from navigation, refrigeration, lighting and entertainment. Across Europe, sailboats, motorhomes and caravans place a premium on compact, maintenance-free energy that recharges efficiently between stops. In Australia, heat, long-distance touring, corrugated roads and remote stays raise the need for vibration resistance, dependable cycling and reliable recovery from limited charging opportunities.

LEOCH addresses these different realities with dual-purpose AGM, True Pure Lead and dedicated deep-cycle batteries. Whether the duty is engine starting, sustained auxiliary power or both, each technology is designed to keep journeys moving and essential onboard systems running.

Designed for How Boats and RVs Really Use Power

Starting, Cycling or Both

Starting batteries deliver high cranking current, deep-cycle batteries sustain onboard loads, and dual-purpose designs balance both duties where one battery must do more.
More from Every Charging Opportunity

Enhanced charge acceptance helps batteries recover efficiently from alternators, shore chargers or compatible solar systems, extending useful energy between stops.
Built for Movement and Seasonal Storage

Vibration-resistant construction, selected sealed designs and low self-discharge support rough water, uneven roads and long intervals between journeys.
Performance Matched to the Journey

AGM, pure lead and dedicated deep-cycle options serve different electrical loads, usage patterns and performance expectations without overcomplicating selection.

From Reliable Departure to Comfortable Arrival

Powerboats & Fishing Boats

Strong cranking supports reliable outboard and inboard engine starts, while matched auxiliary batteries power navigation, fish finders, pumps and onboard electronics.
Sailboats & Houseboats

Deep-cycle batteries supply navigation, communications, lighting, pumps and living systems during long periods under sail, at anchor or away from shore power.
Motorhomes & Camper Vans

Starting and house-battery options support reliable departure and life onboard, from lighting and water pumps to refrigeration, entertainment and selected inverter loads.
Caravans, Travel Trailers & Camper Trailers

Cycle-focused batteries store energy from compatible tow-vehicle, shore or solar charging systems, keeping essential onboard functions available beyond powered campsites.
Trolling Motors & Onboard Equipment

Properly configured battery banks provide consistent power for selected trolling motors, winches, pumps, inverters and other accessories with sustained or high-current demands.

Pure Lead

Faster Recovery for Greater Freedom Onboard

Explore True Pure Lead Technology

When charging time is limited, recovery matters as much as capacity. LEOCH True Pure Lead Technology combines strong cranking, fast charge acceptance and extended cycle life, helping premium boats and RVs recover more energy between periods of use and support heavier onboard electrical loads with confidence.

FAQs

Q. How should marine and RV batteries be charged and stored?

Charging voltage and current must suit the battery technology and capacity, whether energy comes from an alternator, shore charger or solar system. Before seasonal storage, fully charge the battery, disconnect parasitic loads and periodically check its state of charge.
Q. How is a marine or RV battery bank sized?

Sizing should consider system voltage, daily energy consumption, peak loads, required runtime, permitted depth of discharge, temperature, reserve capacity and available charging time. Capacity alone does not confirm whether a battery can support the complete duty cycle.
Q. Can one battery start the engine and power onboard equipment?

A suitable dual-purpose battery can perform both duties when correctly sized. However, boats and RVs with extended house loads may benefit from separate starting and auxiliary battery banks, protecting engine-starting capacity when onboard systems are used for long periods.
Q. What is the difference between starting, deep-cycle and dual-purpose batteries?

Starting batteries deliver a short burst of high current for engine cranking. Deep-cycle batteries provide energy over longer periods and withstand repeated discharge. Dual-purpose batteries balance both characteristics for applications requiring starting and auxiliary power from the same battery.
