The demands on leisure batteries for boats and caravans are different from those of car starter batteries, but Banner Batteries reckon their new Energy Bull leisure battery range recognises these differences and will stand up to leisure use. Robust grid structures, special mass compositions and bag separators arernsaid to give it three times the cycle resistance (the ability to withstand heavy discharging and recharging) of normal starter batteries. And the lid has a labyrinth structure which helps to prevent battery acid from getting out, even in harsh conditions with vibration and impacts that you might find if you're out in a tidal river or bumping and grinding along a shallow cut.
