Installing a boat battery is an easy procedure if you carefully follow the recommended steps:
Start by removing the older battery (if there is one) by switching it off and removing its wires also.
Place the new battery in its box and secure it in.
Grease the terminals before connecting the cables.
Start by connecting the cables to the positive terminal and then attach the second cable to the negative terminal.
Clear any wires out of the way as they will get stuck with the lid of the battery box.
Check the connection before operating. It is ideal that the batteries have a soft and firm connection.
Close the lid of the box and operate it as per your need.
