Check your electrical connections:

Make sure battery terminals and cable connections are clean and tight to enable proper current flow. Corrosion at the battery terminals can prevent a car from starting by adding electrical resistance, so it is important to clean the terminals periodically using water and a wire brush. Ensure you wear the correct protective gear (gloves and eye protection) as the white powder (lead sulphate) is toxic if inhaled, ingested or comes into contact with your skin.

Keep batteries clean and dry

A dirty battery surface can lead to a discharge and corrosion. It is important to avoid spilling oil or grease onto the top of the battery.

Keep your battery charged

Under-charged or under-used batteries will slowly go flat over time which will reduce the life of your battery. This happens most often in watercraft through the winter months or vehicles left unused for long periods of time. It’s important to keep a battery fully charged to ensure maximum life.
