- Parasitic drain diagnosis when batteries keep dying
- Alternator and starter diagnosis and replacement
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.
Why did my battery die with no warning?
Modern batteries rarely fade politely — they fail suddenly, especially after a hot summer or in a car that lives on short trips. We test the battery, the charging system, and check for parasitic drains, because replacing a battery a bad alternator killed just schedules the next tow.
Why does a European car battery need to be registered or coded?
BMW, Mercedes, Audi and others manage charging based on the battery’s age and type. Install a new battery without registering it and the car keeps charging like it’s old — overcharging the new one and shortening its life. We code every replacement properly.
