A leisure battery is specifically designed to be continually ‘cycled’. This means that energy is taken out (discharged) and then energy put back in to the battery (recharged), via a battery charger. Leisure batteries are specifically designed to be cycled and therefore it’s critical that the battery is recharged immediately following its discharge. Leaving a leisure battery in a discharged state for any length of time will cause damage to the battery, which in turn will result in premature failure or greatly reduced product life.
