Key takeaways

  • Check the gear selector — 'D' or 'R' won't crank.
  • Wiggle the terminals — loose or corroded connections mimic dead batteries.
  • Only jump-start with the correct polarity and stable clamps.
  • Two jumps in a week means it's time to replace, not re-jump.

Two quick checks

Confirm the shifter is in Park (automatic) or Neutral. Try starting with the brake pedal firmly pressed — some push-button vehicles require it. Then pop the hood, check that both battery terminals are tight, and look for green or white powder that suggests corrosion.

Safe jump-starting

Red to dead-positive, red to donor-positive, black to donor-negative, black to a clean bare-metal ground on the dead vehicle (not the dead battery's negative terminal). Start the donor, wait one minute, then start the dead car. Let it run 15+ minutes to recharge.

When to stop jumping and start replacing

If the car needs a jump more than once in a few days, the battery is done. Continuing to jump-start damages the alternator and leaves you stranded again — usually somewhere less convenient than the first time.

Frequently asked questions

Can Go Ape jump-start any vehicle?

We jump-start light-duty passenger vehicles, including hybrids and EVs for 12V starter systems. We do not service motorcycles or heavy-duty trucks.

Will a jump start fix a dead battery permanently?

No. A jump gets you moving; it doesn't repair a failing battery. Get it tested that day.
