How do I maintain my boat battery over winter?
A multistage charger like SmartCharge will charge and maintain the battery.
How do I know when to replace my boat battery?
Boat batteries are more important than a car battery because the consequences of a flat battery are more serious. The average life of a battery is around 3-4 years, although they can last up to 6 years in the right conditions. Keeping your batteries connected to a maintenance charger when not being used will help maximise their service life. Regular testing, or a regular replacement program would be a proactive approach to ensuring you never get caught in the middle of the bay with a flat battery.
How do I jump start my battery safely?
Jump starting a boat is not really any different to a car except you need to make sure there is reasonable ventilation before connecting the battery. Many boats have the battery in a confined space so you need to make sure there are not any fuel fumes before jumping.
What are the risks to engine computers from jump starting or using the wrong battery?
Marine control modules are at least as durable as a car module and the consequences of a failed module are more significant than a car. Using a quality jump starter like the IS-1500 is the best insurance policy.
What’s the difference between a car and boat battery?
A boat battery needs to be able to withstand vibration; the manufacturers achieve this by adding support using hot melt glue to lock them in place. Marine batteries also need to be able to deal with cycling deeper than a car battery.
Are deep cycle batteries better than starting batteries for boats?
True deep cycle batteries are not designed for starting engines. Marine batteries are generally what we call a starting & cycling battery. They are designed to tolerate some deep cycling as well as deliver the ‘punch’ needed to start the engine. Marine batteries have a lower CCA rating then their automotive equivalent, however an automotive battery is not designed to be repeatedly cycled.
Why do batteries fail?
Lead Acid batteries can fail in a number of ways. Heat accelerates the degradation of a battery. Deep cycling will reduce a battery’s life as it causes the active material to break away from the lead grid. Allowing the battery to run flat will accelerate sulphation, especially if it is not charged again immediately.
How to extend the life of a boat battery?
Keeping it fully charged when not in use by connecting a multistage charger is the best way to maximise battery life.
If battery fails on the water are there some “hacks” that may get one more start out of it?
Not really. The only (slim) chance is if the battery is cold is to warm it up to 25 or 30 degrees, which will allow it to deliver a little more starting power however this would be difficult if the boat doesn’t have power. The best solution would be to keep a jump pack (like the IS-1500) on board.
