Why Boost Voltage?
Absorbed Glass Mat batteries, otherwise knows as AGM batteries like Optima, Odyssey, Northstar, benefit from higher voltage than standard flooded lead acid batteries. Most vehicles have alternators designed to output a lower voltage for regular 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 spec.
VoltageBoosterPRO is an all-in-one, plug and play modification to boost your alternator voltage output.
Adjustable
Get maximum configurability with a “Low” setting that provides ~0.4V over stock. The “High” setting gets you ~0.8V for the most power when you need it.
1 Minute Install
Remove your Alternator Sense fuse. Plug in the VoltageBoosterPRO. Adjust for LOW or HIGH output.
Over engineered. Durable. Robust.
