Multi-battery isolators have the ability to charge more than one battery simultaneously from a single power source, not requiring a parallel connection of the battery terminals. The main reason that this is beneficial is due to the fact that a weaker battery connected to a stronger battery will end up draining the charge from the stronger battery. One battery is dedicated to holding the charge for starting up the vehicle, the other battery used for a range of things, including car radio equipment or powering portable devices. Their purpose is to ensure that the starting battery has enough power so that the engine can start and batteries can recharge in case the auxiliary battery fails or drains too much energy.
These isolators are normally used in larger vehicles rather than regular automobiles, like recreational and utility vehicles, boats and planes; they are used in vehicles with large, high-power car stereos and off road vehicles to accommodate high current loads.
In order to determine the correct multi-battery isolator for one’s vehicle, there are a few factors. Size is an important factor. The isolator should have an amperage rating equal to or greater than the peak current output in order to interact properly with the vehicle’s alternator system. Utilizing the recommended wire sizes for specific connection distances is also a factor to optimize the use of the right isolator. Choosing the correct isolator also depends on the number of alternators one has or the amount of desired batteries the system will charge.
