Confirmed Vehicle Fitment

Activation & Setup: This is a "Fresh Pack" battery. It includes a pre-measured acid pack that must be added to the battery before the initial seal. Once filled, let the battery sit for 30–60 minutes to "breathe" before capping and installing. For maximum service life, we recommend a 1-hour trickle charge after sealing.
