Often just low
- Lights, a dome light, or an accessory left running drained it.
- The truck sat for days without a drive.
- Cold weather pulls more out of a battery than a mild day does.
In those cases a jump usually gets the truck going again.
Commercial trucks, 12 and 24 volt, dead batteries
Semi and commercial truck jump start
Dead battery on a commercial truck, 12 or 24 volt. The van comes to the truck, at the roadside, at a scale, or in a yard. Tell us where you are, what truck it is, and what happened, and we head out to try a jump.
Semi trucks, truck tractors, dump trucks, garbage trucks, and box trucks. Both 12 and 24 volt systems. Not every dead battery holds a jump. If yours does not, we tell you what we saw.
What a jump can do
A jump gets a truck moving again when the battery itself is simply low. It does not fix everything that can leave one dead.
Something else going on
- The truck cranks but will not catch, or catches and dies again.
- A jump does nothing at all, not even a click.
- It held a jump yesterday and is dead again today.
- Corrosion, a loose cable, or a smell at the battery.
Tell us if any of this is what you are seeing. We still come out and try. If the truck will not hold a start, we tell you exactly what the jump showed, so you know what to do next.
What happens on a call
- You call or text. We ask where the truck is, what truck it is, 12 or 24 volt if you know, and what happened.
- We head out. Roadside, a scale, or a yard, wherever the truck is parked.
- We connect and attempt a start. Hazards on, everyone clear before anything is connected.
- If the truck holds a start, you are back on the road.
- If it does not, we tell you what the jump showed, plainly, so you know what to do next.
What to tell us
Three things get the right help moving.
- Where the truck is. Highway, direction, and the nearest exit or mile marker. In a yard, the address and a gate contact.
- What truck it is. The type and the make, and whether it runs 12 or 24 volt, if you know.
- What happened. Will not crank, clicks but nothing happens, cranks but will not catch, or started and then died again.
If your carrier needs a PO or an authorization number before work starts, get it while we drive. We can talk to dispatch directly if that is faster.
Copy and send
Truck will not start. Freightliner day cab, no trailer. 880 north past Hegenberger, right shoulder. Cranks but will not catch. Jump start called, (408) 466-2844.
Then hazards on, get behind the barrier, and keep your phone on. We call when we are close.
Jump start questions
Can you jump start any truck with a dead battery?
Not always. A jump gets a truck moving again when the battery itself is simply low. If the truck cranks but will not catch, or does not respond at all, that points at something a jump cannot fix. We still come out, try the jump, and tell you exactly what we saw.
Can you jump a 24 volt truck?
Yes. The booster handles both 12 and 24 volt systems. If you know which one the truck runs, tell us when you call.
What should I tell you when I call?
Where the truck is, what truck it is, 12 or 24 volt if you know, and what happened: will not crank, clicks but nothing happens, cranks but will not catch, or started and then died again. That tells us what to expect before we roll.
Do you jump start trailers?
No. Jump starts are for the trucks: semi trucks, truck tractors, dump trucks, garbage trucks, and box trucks. If it is another commercial truck, call and tell us what it is.
The jump does not hold. What happens next?
We tell you what the jump showed: nothing at all, a slow crank, or a start that does not hold. We do not diagnose beyond that on the roadside. Whether it needs a mechanic or a tow is your call from there.
Where do you do jump starts?
At the roadside, at a scale, or in a yard. Wherever the truck is parked, tell us when you call.
What happens if I call after hours?
The number on this page rings the phone that rides in the van, at any hour. If it goes to voicemail we are on another call, so leave the location, the truck, and what happened, and we call back.
Dead battery right now?
Not urgent? Text us with where the truck is and the tire size, and we call you back.
