Optimate 2 is weatherproof, very easy to use, simply connect to the battery and plug it into the nearest power socket, the rest is fully automatic. With 0.8A constant current Optimate 2 automatically brings the battery to full charge and then switches to the unique Optimate battery saving maintenance charge mode to keep the battery at 100% ready and at the same time provides power to the on board computer, display or anti theft alarm.
