What's involved

What this repair actually is.

We remove the corrosion that builds up on battery posts and cable clamps, replace terminal ends that are too eaten-away to save, and apply a protective coating to slow future buildup. Bad terminal connections mimic a dead battery or bad starter, so this small job often solves what looks like a bigger problem.

Symptoms

How you can tell.

  • White, green, or blue crusty buildup on the battery posts
  • Intermittent no-start that fixes itself when you wiggle the cables
  • Clock and radio presets resetting randomly
  • Slow cranking despite a fairly new battery
  • Electrical gremlins that come and go
If you delay

Corrosion keeps spreading into the cable itself, and a job that costs under a hundred dollars becomes a full cable replacement.
