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. Blue Sea Systems Tech Tip: Automatic Charging Relays Explained We do recommend consulting with a mechanic or technician in the process of choosing an ACR and its features. One relay will be open, while the other will be closed.Vulnerable products will be shielded by isolated batteries.Batteries are isolated, and the relay is open.

Open voltage ranging between 12.25 and 12.75 volts.

Combines batteries and closed relays for extended length of time.

No present charge charge input loads will not exceed set limit.

Batteries will share the present charge.

You will then need to carefully consider which preset ACR settings to choose, followed by the product features. The continuous rating will need to reach levels above the highest alternator output rating, and the intermittent rating will need to be above the biggest load for the battery. You will need to take into account the continuous rating and the intermittent rating. When selecting a particular Automatic Charging Relay (ACR), there are many things to consider in order to get the correct system for your application.
