7.6.1. Maintenance of batteries
The batteries delived ex factory (BAVARIA Yachtbau) are AGM batteries, they are maintenance-free. Replace
those batteries with equivalent AGM batteries only.
» Coat battery terminals with silicone grease.
» Keep the batteries clean and dry.
» The life of some battery types is shortened if drained to zero charge. It is recommended that a battery not be
dischargedmorethan50percent.Ifthebatterydoesbecomerundown,rechargeitassoonaspossible.
» Running the engine to recharge the battery may not be effective. The alternator only creates charging power at
higher engine speeds. Idling for long periods will not generate enough power to recharge the battery.
» Ifyouneedtochargeabattery,useonlyabatterychargerdesignedtochargeautomotive/marinebatteries.Use
chargeronlywhenbatteriesaredisconnectedfromtheboat‘selectricalcircuit.Followthemanufacturer’sinst-
ructions when using the charger.
» If your boat will not be used for several weeks remove the batteries from the boat and connect them to a charger.
