The maintenance-free Vetus batteries are especially designed for the demands of seagoing vessels. The batteries can be applied for engine and on-board net supply at the same time. The battery will not suffer any damage, even at -30˚C, so you can leave it on board during the winter without worrying. The Vetus batteries are 25% lighter and approx. 40% smaller than standard batteries. This allows additional installation options in order to boost the power supply. Battery deposit notice for Germany: according to the law, we are obligated to charge a deposit of 7.50 € in Germany (incl. VAT) if the consumer does not return a used starter battery at the time of purchasing a new battery. This deposit is refunded when returning a starter battery.
