How do I choose a battery isolator?

Look for a small plate with printing on your alternator indicating the maximum amperage (measured in Amperes) for your car system. The battery isolator that you select should have an amperage rating “equal to or greater than the peak current output” of your alternator.

Do I need a battery isolator car audio?

Can you run two batteries one alternator?

A car alternator will be more than capable of charging two batteries. The first is if both batteries are low on charge then that would be too much for the alternator, but if only one is low then it would be fine. The second thing is linking the batteries will cause more problems.

How do isolators work?

Electrical isolators work by separating part of the electrical power from a system for safety during maintenance works. This is usually done by an off-load condition.
