Battery Isolators Explained - A Must Have For Powerful Systems
Battery isolators are those alternator and trouble saving devices that separate your primary battery system from your auxiliary battery. Most people run their amplifiers and added accessories from a secondary amp to lighten the load on other factory installed devices. Here is a look at how they work and why they are important.
The diode based isolators are basically two high current diodes. These diode isolators are known for their durability and long life, and seldom fail. They do however sacrifice a little power due to the 0.5 volt drop of the incoming charge. This voltage drop will keep the battery from reaching maximum charge, but will allow it to maintain a high enough charge during peak use to keep your headlights and other devices from dimming, and power your amplifiers and added accessories.
