These will cost more than the other options due to limited market acceptance.Īpplying one of these three concepts to your alternator will bring about different advantages and will inevitably improve the lifespan and quality of your batteries.

Zero Drop Isolators:These isolators are useful in addressing the problem of voltage- dropping.Also, the heat levels will most likely rise, and the currents will split. However, because of the presence of diodes, the voltage is more likely to decrease, which consumes more energy and does not charge batteries quite as quickly. Battery Isolators:Currents will flow more swiftly to the battery.An Automatic Charging Relay allows the current to pass easily from one battery to the next. The relay will open, and the two batteries will be isolated. When the charge is inactive or overloaded, the voltage will drop to around 12.75V DC. Automatic Charging Relays:Combined voltage and relays that reach over 13V DC will charge two batteries at the same time.There are a few main styles to choose between: This benefit is useful in the case of one battery failing and having another battery as an emergency back-up. Doing so, keeps the batteries isolated when not charging. Here you can learn about Automatic Charging Relays, Battery Isolators, and Zero Drop Isolators.Īutomatic Charging Relays allow two banks on a vessel's alternator to be charged simultaneously from one unit.
