Which marine battery should you choose?
A marine battery is not just a battery. There are different types, each designed for specific needs. The right choice, therefore, depends on how you use your boat.
- Starter battery - Ideal for those who have an engine that requires a high starting current. These marine batteries deliver a fast and high power to start the engine, but they're not made for long-term loads.
- Consumable battery - A consumable battery is the right choice if you have electrical equipment and marine electrical appliances like sonar, electric winches, coolers or the different lanterns on board. It provides a steady power supply and energy over a longer period of time.
- Dual-purpose battery/dual battery - A combination of a starter and consumer battery, ideal for smaller boats with limited space.
Capacity and lifespan of marine batteries - important factors
When choosing a marine battery, you must look at capacity (Ah) and lifespan. Capacity tells you how much power the battery can deliver over time, while lifespan depends on battery quality and maintenance.

Marine batteries are designed for boats to power the engine and electrical equipment. They can withstand moisture, vibration and deep discharge better than car batteries. There are starter batteries, consumer batteries and combined batteries, depending on whether you primarily need to start the engine or power equipment.
Which battery is best for boats?
It depends on the needs of the boat. Starter marine batteries provide high starting current, consumer batteries provide steady power for equipment, while dual-purpose batteries combine both functions. Choose a marine battery with the appropriate capacity and ensure it can handle your power requirements for optimal performance and lifespan.
How long does a marine battery last?
The lifespan of a marine battery is typically 3-7 years, depending on usage and maintenance. Regular charging, proper storage and avoiding deep discharge will extend the lifespan. The quality of the battery and temperature conditions also play an important role in how long it performs optimally.
