![]() ![]() 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. Over Voltage Lockout: 12V, Under Voltage Lockout: Weight: 25 lbs.Boat Battery Isolators & Charging Relays How-Tos Selecting the Correct Automatic Charging Relay.Amperage Operating Current: 175mA (combined), 15mA (open).Ignition protected ACR and switch can be installed in engine rooms of gasoline powered boats.Tin plated copper studs on the battery switch provide maximum conductivity and corrosion resistance.Simplifies switching for two battery systems.Provides an emergency combine feature to draw power from both batteries.Automatically isolates house battery during starts to protect electronics.Allows two batteries to be efficiently charged from a single charging source without external regulators or isolators.It can be surface or rear mounted for a cleaner look. This battery switch is ignition protected and compatible with installations in engine compartments of gasoline powered boats. This eliminates the risk of draining the start battery by leaving the stereo on too long or running the trolling motor too much.īackup starting power: However, if there is a time that extra power is needed from the battery with a charge, the combine features allows you to draw power to start the engine or make an emergency radio call. While in the ON position, both house and start batteries provide power, but are separated giving power to only the circuits dedicated to each battery. Prevents dead batteries: The included battery switch, a Blue Sea System e-Series Dual Circuit Plus™, is packed with features. Because the ACR is ignition protected, it can be installed within the engine room. The ACR will share the charging source more efficiently than a battery isolator-without creating a voltage drop-and will not require additional wiring or an external regulator installation is straightforward. It combines the two batteries while charging, and isolates the house battery to protect sensitive electronics while starting the engine. ![]() The included battery switch provides an emergency combine feature that can get you out of a jam.ĪCR combines or isolates battery banks: The automatic charging relay (ACR), a Blue Sea Systems 7610, performs several tasks. That is until one battery can no longer supply power. It also helps to keep the two power sources separate so that you are only drawing power from the battery you want to. Single charging source: The kit allows you to charge your new and existing battery from a single charging source often your engine. Both components are designed to withstand a life on the water. The Blue Sea System Add-A-Battery™ kit packages a switch and an automatic charging relay (ACR) to help protect and maintain the additions to your boat. If you are adding a second battery to support a larger stereo, a trolling motor or a new fishfinder, this kit is an essential part of the installation. Adding a second battery to support your new electronics or trolling motor? Charge it and use it as an emergency backup with an Add-A-Battery system. ![]()
