The experts at Smith Auto Electric can determine which unit you will need.Īt Smith Auto Electric we carry the Duvac II battery equalizer by Sure Power. Many of the newer alternators are internal sensing and so cannot be used with an isolator, because of the loss of approximately 1 volt across the diodes, In these cases you would use a battery separator. The difference in whether to use a battery isolator or battery separator will depend on whether your alternator has internal or external voltage sensing.

Voltage Spikes - generated by the coil of the solenoid are absorbed by protective circuitry built into the Battery Separator.

Universally Suited - for mounting on two vehicle or towable.

Start Assist Feature - an optional input from the key or manual switch will program the Battery Separator to parallel the batteries during starting.

Prioritized Charging - waits until the battery connected to the activated charging source reaches 13.2 volts before paralleling and charging the remaining batteries.

Multiple Battery Charging - allows multiple batteries to be charged from one charging source.

Simple Installation - connects to primary battery, auxiliary battery and ground.

Thus multi-battery problems are solved.Ī BATTERY SEPARATOR can also be used, instead of an Isolator and includes these features: The balanced circuit electronic isolator is one of the best ways to maintain proper isolation and control. With this system, the alternator is protected, the batteries are protected and your family or passengers are protected. Each battery then determines the amount of current which flows into it by its own state of charge, based on the voltage regulator setting. When the alternator is charging, current can only flow in one direction, from the alternator to the batteries. When the current is used from battery #2, the check valve (diodes) stops current flow from battery #1. 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. Many vehicles and other types of equipment have multiple batteries.
