Battery Storage

[iaaems]

I used to sell batteries at one time in my life and these were always delivered to us 'dry charged'. When a customer wanted one we would pour in the required amount of acid and give it a low boost on the charger to kick it into life. These were car batteries by the way. I would assume that a deep cycle battery could be treated the same way - the deterioration in performance only starts to happen when the acid and metal are brought into contact with each other. There is a web site at http://www.courtiestown.co.uk which might just be able to help with the longevity of batteries - they have something called a 'battery desulphator'. I'm not sure what this does but it might be helpful/interesting.
