Additional Battery Power

I have a 2016 22FB Sport with only one battery that discharges fairly quickly when shore power or generator is not available. The battery is depleted within 2 days of limited use. Would like to add an additional battery for extended power life. Any advice on battery size or mounting?

If you intend to increase your battery power with an additional battery, you will need TWO new units as your present battery has taken a 'charging profile' and the addition of a new battery will cause a situation of eleven charging between the new and old cells resulting in one battery receiving most of the charge and the other one not.

In any case, both of your new batteries should be of the same brand and preferably identical.........I say 'preferably' as Lifeline has stated that they have tested and used varying sizes of their AGM batteries in a single battery bank with no ill effects. I would not suggest this with any other battery, as the results are unknown.
