If you have ever inspected the battery systems on a trucking fleet, recreational boats and other recreational vehicles, and airplanes then you probably would have come across a battery isolator.
The main objective of a battery isolator is to ensure that the starting battery is sufficiently charged to start the motor. On vehicles such as the ones mentioned above there are often two separate batteries. The first battery starts and runs the motor while the second operates accessories such as winches and other associated instruments.
Battery isolators are also used to charge different batteries simultaneously. This can be done without connecting the batteries in parallel. If two batteries are connected together and one is sufficiently undercharged then it will end up draining the charged battery.
The battery isolator or switch will divide the direct-current which allows for simultaneous charging from a single point or power source. An example of this may be a solar panel or an alternator. By breaking the current up into a number of different single-flow branches a battery isolator can simultaneously charge multiple batteries while preserving the life of the remaining batteries if one in the system should fail.
