A jump start fixes a drained battery but not the reason it drained. If the engine cranks strongly after the boost and keeps running, you are done. If it dies again, the battery or alternator is failing and you need a tow; Boston-area towing prices published by other providers run about $50–$125.
Jump-start calls come down to one decision: boost or tow. A jump is the right call when the battery went flat because of something obvious, like an interior light left on overnight. It is the wrong call when the car has been slow to start for weeks.
Boston Towing Service answers Mon–Fri Open 24 hours, closed Sat–Sun. Tell the dispatcher how the car behaved before it died, because that decides which truck and which tools make sense.
How do I tell a dead battery from a bad alternator?
Listen first. Rapid clicking or no sound at all points to a flat battery. A car that started fine, then lost power while you drove and showed a battery light on the dash, points to the charging system.
In the first case a jump usually gets you moving. In the second, the car may start with a boost and then die within minutes, so drive straight to a repair shop only if you are sure it will make it.
What if the dead vehicle is a box truck or work van?
Larger commercial vehicles, especially diesels, often carry more than one battery and draw more to turn over. Say what you drive when you call so the right equipment comes. Also mention if the vehicle is blocking a loading area or driveway.
Do not keep cranking while you wait. Repeated attempts drain whatever charge is left and can overheat the starter.
When is a tow the better choice?
If the battery is old, the terminals are corroded, or the car has needed a boost before, a jump only postpones the next call. Towing it to a shop costs more today and may be cheaper than being stranded twice.
Ask the dispatcher which they think fits your symptoms. A good dispatcher will tell you honestly if a jump will not hold.
How long should I run the car after a jump?
Drive it long enough for the alternator to put some charge back in, and avoid shutting it off until you reach your destination. If it will not restart afterward, the battery likely needs replacing.
Can I jump-start a car in the snow?
Yes, but cold batteries lose strength, so a boost may take longer to work. Clear snow from around the hood and terminals and stay clear of moving traffic while you wait.
Does jump-starting damage the car?
Done correctly it does not. Connecting cables in the wrong order or to the wrong terminals can damage electronics, which is why many drivers prefer a trained operator for newer cars.
