First, don’t substitute one battery type with the other. For instance, if you think you can power up your appliances using a boat starting battery, you might have to compromise with power requirements. Second, keep the battery bank clean during usage and also when not in use. Third, keep checking for any corrosion. If you see any, a solution of baking soda and water can work. All in all, the upkeep of boat batteries is all that requires to let them running smoothly. Spend time in their maintenance, do a regular checkup, and you are good to go.
