What it is
A van or truck service that tests car batteries and charging systems, then fits a new battery in a driveway, parking lot or workplace. You also take the old battery away for recycling.
Your first three steps
- Price the common battery sizes from local wholesale suppliers and decide your service fee and service area by zip code
- Buy a quality battery and charging system tester, memory saver, hand tools and a lifting strap, and set up a Google Business Profile
- Contact local tow companies, repair shops and small fleets to offer overflow battery jobs, and ask your first customers for reviews
Who pays
Drivers with a dead battery, busy commuters, small businesses with work vehicles, and local car dealers or rental lots.
How it makes money
You charge the battery price plus a flat service or call-out fee, and sometimes a core charge that is refunded when the old battery is recycled. Fleet clients can bring repeat work.
