Marine Batteries in Perth.
Flat Prices, No Hidden Costs. Installed And Delivered Across Perth.
Marine batteries are real workhorses. Not only is a boat battery needed to provide the power necessary to start the boat’s engines, a second battery is also needed to power the on-board equipment, which can range from the essentials such as GPS, nav lights and console equipment, to high-consumption items like fridges, radios and TVs.
Deep Cycle Batteries are often used in a dual system on boats, where the ignition is provided by a standard (Stop Start) battery, leaving the deep cycle battery to power the on-board equipment.

Marine Battery FAQ's
We’ve answered some frequently asked questions to help you with your battery.
A marine battery is a specialized type of battery designed for use in boats and other watercraft. These batteries are designed to withstand the harsh conditions of the marine environment, including exposure to saltwater and vibrations from the boat’s engine.
When choosing a marine battery, you should consider the type of boat you have, the amount of power you need, and the size of the battery compartment. You should also consider the battery’s capacity, voltage, and type, such as flooded, AGM, or lithium-ion.
To maintain your marine battery, you should keep it clean and dry, avoid overcharging or undercharging, and store it in a cool, dry place when not in use. You should also check the battery’s water levels regularly and top up with distilled water if necessary.
A deep cycle battery is designed to provide a steady flow of power over an extended period of time, while a starting battery is designed to provide a short burst of power to start an engine. Deep cycle batteries are often used in boats for auxiliary power, while starting batteries are used to start the boat’s engine.
While it is possible to use a car battery in a boat, it is not recommended. Car batteries are not designed for the marine environment and may not be able to withstand exposure to saltwater and vibrations. Marine batteries are specifically designed to meet the demands of the marine environment.
The lifespan of a marine battery can vary depending on the type and usage. Typically, a properly maintained marine battery can last between 3 to 5 years. However, extreme temperatures, overcharging, and undercharging can shorten the battery’s lifespan. It is recommended to replace your marine battery every 2-3 years to ensure reliable performance.
