Replacing the Battery May Not Be Enough

If a new battery also dies, the vehicle needs charging and draw testing. We look for components that stay awake, wiring faults, and charging problems.

Questions

Battery Drain FAQ

Quick answers before you schedule a visit.

Why does my battery die after sitting?

Common causes include a weak battery, parasitic draw, short trips, or a charging system that never fully restores the battery.

Can you test for parasitic draw?

Yes. Draw testing measures current after modules go to sleep and isolates the circuit when needed.
