Leisure batteries (when not maintenance free) require topping up at

intervals. 2 monthly should be fine, if you install some sort of charge

Errrm, if he fits a solar panel and a Rutland (or similar) controller the
idea is that the battery will be topped up continuously in daylight hours.
The problem is that in winter the days will be short, the sun will be of
much lesser intensity and snowfall or days of low cloud will leave the
possibility that the panel fails to charge the battery. This is why a
second source such as a wind generator is a good idea.
