A dead battery is the most common reason a car will not start. A technician connects a professional jump pack, starts the vehicle and, ideally, tests the battery and charging system to see why it went flat. That second step matters: a jump start gets you moving, but if the battery is at the end of its life or the alternator is not charging, the car will be dead again at the next stop.

  • Jump start with a professional booster pack
  • Battery and charging system test
  • Terminals checked and cleaned of corrosion
  • On-the-spot battery replacement where offered
  • Tow arranged if the vehicle still will not start

Battery, alternator or starter?

A rapid clicking or slow, labored cranking with dim lights points to a weak battery. A single click with bright lights and no cranking points to the starter. A car that starts with a jump and then dies again while running, or shows a battery warning lamp while driving, points to the alternator or its belt. If the lights were left on overnight, the battery is simply drained and may recover fully with a drive or a charge.

How long batteries last here

Car batteries typically last about three to five years, and heat shortens that. A battery that has been jump-started more than once in a short period, is more than four years old, or tests weak should be replaced before it leaves you stranded. After a jump start, drive for at least twenty to thirty minutes, or put the battery on a charger, to restore its charge. Short trips will not do it.

Hybrids, electric vehicles and modern electronics

Hybrids and electric vehicles still have a 12-volt battery that runs the computers and unlocks the high-voltage system, and it can go flat like any other. It can usually be jump-started using the designated terminals, which are often not at the battery itself. Follow the owner's manual exactly. Never attempt to jump the high-voltage battery, and do not use a hybrid or electric vehicle to jump-start another car unless the manufacturer says it is permitted.

Jump Start Service FAQs

How much does a jump start cost?

Each company sets its own service-call rate, and night, weekend and distance charges vary, so ask for the price when you call. If you have roadside coverage through an auto club, your insurer or your vehicle's manufacturer, a jump start is normally included.

Is it safe to jump-start a car myself?

Yes, with care. Connect positive to positive first, then the negative clamp to the good battery and the last clamp to bare metal on the dead car's engine away from the battery. Start the working car, then the dead one, and remove the cables in reverse order. Check the owner's manual first — some vehicles have specific jump points or advise against it.
