FAQ
Common questions
Why does my new battery keep dying?
Either the charging system is weak, something is draining the battery while parked, or the battery was never registered on a car that requires it. All three are diagnosable — guessing is not required.
What is battery registration?
Modern European cars manage charging based on battery age and type. Registering the new battery tells the car to reset that logic. Skipping it undercharges or overcharges the new battery.
Do you install AGM batteries?
Yes — and if your car came with AGM, it must be replaced with AGM.
Window tint, XPEL PPF, ceramic coating, wraps, or detailing?
