Why Boost Voltage?

The Underpowered Battery

Absorbed Glass Mat batteries, otherwise knows as AGM batteries like Optima, Odyssey, Duracell Platinum, AC Delco Gold/AGM, Northstar, and XS Power, specify a higher charging voltage than standard flooded lead acid batteries. Check the label or manual on your battery to see what your AGM battery manufacturer specifies. Most vehicles have alternators designed to output a lower voltage for regular flooded lead acid batteries, not AGM batteries. Continually undervolting your AGM battery can damage it and decrease lifespan, and decrease available capacity. Use the VoltageBoosterPRO to increase your alternator’s voltage output to get your battery within specification, in a package that safely includes a fuse.
