Buyers’ Guide In Purchasing Dual Battery Isolators

The battery isolator is an electrical device that will divide the direct current (DC) into different branches and will only allow current in one direction in each of these branches. The main benefit of this arrangement is for you to be able to simultaneously charge more than one battery from a single power source like the alternator without connecting the battery terminals together in a parallel.

Why Use A Dual Battery Isolator?

The battery isolator is very important when you have a vehicle with a single battery but would want to use another because a weak or dead battery can drain the charge from the stronger battery if both of them are connected directly together. The only disadvantage of this is the added cost and complexity of the setup. If you are using a diode-type isolator, there can be an additional voltage drop in the circuit between the charging source and the batteries.

Uses of Battery Isolators

The battery isolators are used on recreational vehicles, boats, airplanes, utility vehicles, and also with large trucks where only one battery is used for starting and running the engine while the other battery runs the accessory loads. Many of our vehicles are furnished with a single starter battery at the production line, yet a few of us might need to include an additional battery or two to power a winch, a compressor, additional work lights, a sound system, or to increase your camper batteries or maybe a combination of these features. You would want to achieve this without idling the engine. In order for you to do this, you first have to isolate the starter battery from the secondary battery so then it will start when you need it to through the help of the dual battery isolator.
