Battery Testing That Works

Nearly 40% of roadside breakdowns in Germany are caused by battery failure — often with no warning the day before.

A battery does not always announce its decline with flickering lights or slow starts — it can hold voltage at rest and still collapse the moment it faces the load of a cold engine at 6 a.m. in January.

CubarKilo uses load-tested diagnostic equipment that measures cold cranking amps, internal resistance, and state of health in real time, giving you numbers rather than assumptions.

Frequently Asked Questions

The full battery and charging system test typically takes between 20 and 30 minutes. Booking ahead means your bay is ready when you arrive.

Yes. A battery failing internally can still start a warm engine on a mild day, but problems emerge under stress like cold mornings or short battery cranks.

We show you the diagnostic printout and explain the numbers in plain terms. If replacement is needed, we provide the cost and complete it the same day when possible.

Yes, we stock a wide range of batteries suitable for most German vehicle makes. We can replace a failed battery during your visit in most cases.

We recommend annual testing, especially before winter. If your battery is over three years old or you drive infrequently, testing twice yearly is ideal.

For now, testing is available at our workshop. Contact us to discuss fleet or roadside testing options for your business needs.

Why Choose Us

Load Testing

Conductance-based load testing stresses the battery the way a cold start does, revealing failures that simple voltage checks miss.

Printed Results

Every battery test produces a diagnostic report showing cold cranking amps, internal resistance, and charge state that you can keep and compare.

Charging System Check

A new battery fails prematurely if the alternator is not charging correctly. We test both battery and charging system together.
