Did you ever have one of those days when your car just wouldn't start? A battery, like the other parts of your vehicle, is subject to wear and tear and should be checked and cleaned regularly.
Check the battery for cracks, swelling, and frayed or corroded battery cables. If they’re frayed or corroded, the cables and clamps may need to be replaced, otherwise the battery may short-circuit.
If the battery is free from cracks, isn’t swollen and the cables are perfectly fine, always remove the negative cable first. This prevents you from receiving a shock, or damaging electrical components.
Charging a car battery isn’t a one-way street, and you will need outside help – either from a friend, a family member or a kind stranger with jumper cables. Both cars must be in park or neutral, with ignitions shut off and emergency brakes on.
Batteries give off hydrogen gas, and one spark could set off an explosion. If the caps are open, this can be avoided. The sealed batteries have safety valves for pressure relief.
The positive cable has red clips on either end, while the negative cable has black clips. It’s important to attach them in this order:
If it won’t start, make sure that the cables are properly connected, then have the other person run their engine for five minutes before trying to start your car. If your car still won’t start, the battery will need to be replaced.
After disconnecting the cables and thanking the person who helped you, don’t turn off your engine. Instead, drive around to recharge the battery. It may also be a good idea to have your car battery checked.
