Mobile Battery Replacement FAQ — Auxiliary Battery Replacement

  • How much does mobile battery replacement cost?

    A battery replacement starts at $159, all-in — the new battery, labor and the trip included, plus we recycle the old one. Your exact flat price appears after you select your year, make and model.

  • How long does a battery replacement take?

    Most battery replacements take about 30 minutes in your driveway. You'll get a text when your mechanic is on the way.

  • How do I know if it's the battery or the alternator?

    A slow crank that a jump-start fixes for a day or two usually points to the battery; if the car dies again shortly after a jump, the alternator or charging system may be the cause. A mobile test pinpoints it before any repair is quoted.

  • Do you offer a warranty on batteries?

    Yes. Every battery and electrical repair is covered by our 12-month / 12,000-mile warranty on parts and labor, honored anywhere we operate.

  • Can I finance my battery replacement?

    Absolutely. Choose a 0% APR plan at checkout and split the cost into monthly payments — approval takes seconds and doesn't affect your credit score to check.
