> **Quick Answer:** If a jump start failed, you likely need a tow. Expect to pay $75 to $125 for a short local tow (under 5 miles) and $150 to $300 or more for longer hauls. A failed jump usually points to a dead cell in the battery, a bad alternator, or a parasitic drain that a jump cable can't overcome. You need a mechanic, not another jump.
## Why Did the Jump Start Fail?
A jump start fails for three main reasons: the battery has a dead cell and cannot hold a charge, the alternator is not charging the battery even when the car runs, or there is a parasitic drain pulling power faster than a donor car can supply it.
The easiest way to tell the difference: if the jump start gets the engine running but it dies again within a few minutes, suspect the alternator. If the engine cranks weakly or not at all despite a solid connection and a good donor vehicle, the battery itself is likely done. Either way, a jump cable is not going to fix this roadside.
Check your connections first. Corroded terminals (the white or blue-green crust on the battery posts) can block enough current to make a jump look like it failed when the real issue is a bad contact. Scraping the clamps directly against bare metal on the terminal posts sometimes makes the difference. If you have tried that and it still will not start, move on. [A clicking noise when you turn the key](/car-wont-start-clicking-noise-tow-truck-cost/) is a strong signal the battery is completely discharged or the starter is failing.
## What Will It Cost to Tow After a Failed Jump?
A local tow runs $75 to $125 for the first 5 miles, with most tow companies charging $3 to $7 per mile after that. A 15-mile tow to a shop will typically land between $120 and $175 out of pocket if you are paying cash with no roadside coverage.
Some variables that push the cost up:
- **Time of day.** Night, weekend, and holiday calls usually carry a $25 to $50 surcharge.
- **Vehicle size.** A full-size truck or SUV may cost more than a sedan because it requires a larger flatbed.
- **Location.** If you are in a parking garage with height restrictions, the operator may need a smaller wheel-lift truck, which some companies charge a specialty rate for. See [car battery dead in parking garage towing cost](/car-battery-dead-in-parking-garage-towing-cost/) for what to expect in that specific situation.
If you have AAA, most tiers cover 5 to 100 miles of towing depending on your membership level. If you have roadside assistance through your insurer, call them before calling a private tow company. Using an out-of-network tow and filing for reimbursement later almost always pays you less than letting the insurer dispatch directly.
## Is It Safe to Stay With the Car While You Wait?
Stay in the car only if you are off the travel lanes. If you broke down on a highway shoulder, get everyone out of the vehicle and stand behind the guardrail, away from traffic. A car sitting on a shoulder is a real hazard, especially at night or in poor visibility.

ghts immediately and leave them on. If you have road flares or reflective triangles, place them 100 to 200 feet behind the vehicle to give approaching drivers time to react. If you are on an interstate and cannot safely exit the car, stay buckled inside until help arrives.

## Should You Try Another Jump or Just Call the Tow?
Call the tow. If a proper jump with a fully charged donor vehicle or a jump pack has already failed, additional attempts are unlikely to change the outcome and waste time you could spend getting the car to a shop.
The one exception: if you are not sure the original jump was done correctly. Both red clamps go on positive terminals, black clamp on the negative terminal of the donor car, and the last black clamp goes to an unpainted metal ground on the dead car (not the dead battery's negative terminal). If the sequence was wrong or the clamps were on corroded posts, a correct second attempt is worth one more try. If that still fails, stop. You are looking at a battery replacement, an alternator repair, or a diagnostic, none of which happen on the side of the road.

## Common Questions
**Q: How much does it cost to tow a car with a dead battery?**
A: A short local tow (under 5 miles) typically costs $75 to $125. Longer tows run $3 to $7 per mile beyond the base distance, so a 20-mile tow can reach $175 to $250 depending on time of day and vehicle type.
**Q: Can a completely dead battery be jumped?**
A: Sometimes, but not always. A battery that has at least one good cell can usually be jumped with enough charge time from a running donor car. A battery with a dead cell will not hold a charge no matter how long you try and needs to be replaced.
**Q: What does it mean when a jump start works but the car dies again right away?**
A: The alternator is not charging the battery while the engine runs. The jump started the car on the donor vehicle's power, but once disconnected, there was nothing to keep the electrical system going. [A bad alternator needs a tow](/alternator-died-while-driving-signs-and-towing-options/), not another jump.
**Q: Will my insurance cover a tow after a jump start fails?**
A: Only if you have roadside assistance coverage added to your policy. Standard liability or even full coverage does not include towing. Check your policy's declarations page or call your insurer before assuming you are covered.
**Q: How long does a tow truck take to arrive after a failed jump start?**
A: Response times vary widely. In urban areas, 30 to 60 minutes is common. Rural or highway locations can stretch to 90 minutes or more. If you are using a roadside assistance service, they will give you an estimated arrival when you call.
