You get into the car and suddenly find that the ignition is not working and the headlights do not come on. After starting from an external source, you need to find out if you need a new battery or generator. Follow our instructions to check your battery.

Steps

Method 1 of 2: How to check if your battery needs charging

1. 1 Switch off the ignition.
2. 2 Open the positive side of the connector cover.
3. 3 Connect the positive lead of the voltmeter to the positive pole of the battery (the positive lead is usually red).
4. 4 Connect the negative wire to the negative pole.
5. 5 Let the machine stand overnight.
6. 6 Check voltmeter. If the battery is in good condition, the voltage should be between 12.4 and 12.7 volts. If it is below 12.4, then the battery needs to be charged.

Method 2 of 2: How to check the battery after charging or starting from an external source

1. 1 Make sure the car is idling.
2. 2 Connect the positive lead of the voltmeter to the positive pole of the battery and the negative lead to the negative pole.
3. 3 Look at the voltmeter reading.
   • A working system should idle 13.5 to 14.5 volts or more when charging.
   • A reading below 13.5 indicates that the generator is not producing enough energy to charge the battery. Buy a new generator from your local parts store or contact a mechanic.

Tips

• The battery can be checked and charged at your local parts store.
• Most batteries last four to five years, and in hot climates up to three. If you have charged the battery and you see that it does not work, although the car has not run, then simply change the battery.
• After purchasing a new battery, dispose of the old one according to the regulations in your country. Your local store can usually accept the old battery for recycling.

Warnings

• Never short-circuit the battery poles as this can cause severe burns, rupture of the battery, and hydrogen explosion.
