Mechanic thinks he's got routine call from customer who says their car won't start until he checks the battery and is left stunned

A mechanic received what sounded like a routine call from a customer saying their car would not start.

Like all mechanics, expected – and probably hoped for – a flat battery and a quick fix.

But when he lifted the hood, the situation turned out to be anything but routine.

What he found inside left him stunned and made him reach for his camera.

A routine call from a customer that was anything but normal…

A mechanic, featured in a video shared on TikTok, opened the hood to investigate a no-start complaint in a customer’s car.

At first, it looked like any other dead battery job, but then he noticed the casing had split wide open across the top.

The entire upper section had exploded due to internal pressure, leaving the plates and cells partially exposed, which is incredibly dangerous.

Instead of a drained battery, he was staring at one that had physically ruptured from the inside.

It was the kind of failure most techs never see in their whole career, the kind that instantly turns a simple jump start into a full replacement.

With the casing coming apart this dramatically, it was no longer just a no-start situation – it had become a genuine safety hazard sitting inches from the engine and fuel system.

He was stunned by the state of the battery

The mechanic had no idea what he’d be facing when he arrived at the callout, as the customer had only reported that the car wouldn’t start, giving no hint that the battery had essentially exploded.

He removed the blown unit carefully, knowing the exposed internals could spill acid or short out if disturbed.

For the customer, the fix ended up being straightforward because the battery was replaced, and the charging system was checked for any underlying fault, which, luckily, there wasn’t.

Thankfully, the problem was sorted before things got even more dangerous, and it goes to show how important it is to get problems sorted quickly when you discover them.
