So no matter how drained your accessory batteries become, they will never drain power from the battery you're depending on to start your engine. Each battery is isolated and acts as an independent power source. The BATTERY ISOLATOR acts as a check valve between the batteries, preventing current from flowing from one battery to another. To eliminate the multi-battery drain problem, a Sure Power BATTERY ISOLATOR or BATTERY SEPARATOR (smart solenoid) can be installed. AN AUTOMOTIVE TYPE SOLENOID IS NO SOLUTION FOR MULTI-BATTERY DRAIN. This sudden, violent transfer of energy from one battery to another has been known to damage batteries or shorten their life and overheat wires and connections. But the second the solenoid reconnects the batteries, the drained battery robs power from the starting battery. With a solenoid, there's no multi-battery drain while the batteries are disconnected. One of the 'so-called' solutions for multi-battery drain is nothing more than an automotive type solenoid, a switch that disconnects batteries one from another. If it's allowed to continue unchecked, it can leave you stuck with dead batteries and an engine that won't start. This is the problem of multi-battery drain. So no matter how many batteries you have on your vehicle, the accessories connected to one will draw power from the other batteries in the circuit. The discharged battery will always rob power from a charged battery.

If a fully charged battery is connected directly parallel with a discharged or empty battery, the voltage pressure in the full battery will force its current into the empty battery until the current stored in both batteries reaches a common level. It's important to think of batteries as storage tanks. The current then flows through the wires (pipes) to the accessories. The alternator pumps current (water) into the batteries (storage tanks). Electrical current is equal to the flow of water and voltage is equal to the pressure. To understand the problem of multi-battery drain, and how a Sure Power Battery Isolator prevents it, think of electricity as water. one to start the engine, and others to power accessories. Howard Kelsey from Tulsa, OK United StatesĪrrived as promised, exact replacement for existing switch.Īnonymous Person from San Ramon, CA United StatesĮxact form factor as 1314-200 that it replaced on my RV that had solar panels installed.Many vehicles and other types of equipment have multiple batteries. Others with on-line stores can't tell you if they really have your item in inventory or are going to have to backorder it. ASE confirmed for me on the phone that they really did have it in stock.

I needed this unit to replace one in my RV that had failed. Great service - fast, friendly, responsiveĮdward Hershberg from Portland, OR United States William Efimoff from DERIDDER, LA United States Thus providing the starter system with maximum battery voltage available.Ġ of 0 people found the following review helpful: When the engine is started, the start signal causes the controller to check if the auxiliary battery is within about 0.85V of the main battery if so, the relay contact is closed. This will cause the relay to be opened shortly after the engine is stopped, attempting to preserve 100% of the starting battery capacity for engine cranking. The disconnect voltage is set to a nominal 12.8V, which is near the full charge resting voltage of the batteries.

This will cause the relay to close and the charging system can charge both banks of batteries. The connect threshold is set to a nominal voltage of 13.2V, which would only be reached when the charging system is operating. If the main battery (for the 1314-200) or either batteries (for the 1315-200) are below the disconnect threshold the unit will open the relay. If the main battery (for the 1314-200) or either battery bank (for the 1315-200) is above the connect threshold, the relay connects the two banks together. The units monitor both the main and auxiliary battery banks. The 1314-200 (unidirectional) and 1315-200 (bidirectional) are 200A battery separator modules with an integrated relay for 12V systems.
