Second leisure battery


Recommended Posts

When fitting a second battery, I always connect the two batteries diagonally to ensure that both are worked equally and the second is not just a 'back up' slave to the first because it is reckoned by some experts (there's that word again - expert!) to help with battery life expectancy and that is a good enough reason for me!

Just found this when researching how to connect them up.

Would have been useful when I had a narrow boat with four batteries, but with two it just seems you connect diagonal pole to balance the current.


Interesting link Thank You.

But how often do we draw 100 amps from our leisure batteries?
