Replacing Your Marine & Boat Battery
- Check the type of battery required. Boats will typically have a deep cycle and a starting battery.
- Locate the current battery. Open the casing or compartment.
- Marine batteries usually have nut & bolt terminals. You will need pliers to loosen the connectors.
- Disconnect negative (black) terminal first, then positive (red) terminal.
- Remove batteries. These are heavy so ask for help if needed.
- Insert new batteries. Attach positive (red) terminal, then negative (black) terminal. Use a wrench to ensure connections are snug.
- Close the battery compartment and replace any other disassembled pieces.
- Recycle old battery.

Marine & Boat Battery Care
- Visually inspect the battery regularly (once per month).
- Clean battery terminals occasionally with baking soda and water solution or a commercially available battery terminal cleaner. Make this part of your routine maintenance schedule. Keeping battery terminals clean will extend the battery life.
- Ensure terminal connections are tight and do not loosen over time. This will help prevent corrosion and unwanted discharge.
- Coat terminal connections with grease or other lubricant to prevent unwanted discharge.
- Ensure the battery is brought up to full charge when not being used. Batteries which fully discharge will have a shorter life and degraded performance.
- Store battery in cool, dry place (68°F/20°C).
- Recycle batteries, do not dispose.
