There’s a specific kind of frustration in turning the key and hearing nothing but a faint click, especially when you’re already running late or it’s the middle of the day in Dubai’s heat. If you’ve got another car nearby, charging your battery from it is usually the fastest fix, but it only works safely if you connect the cables in the right order. Get it wrong, and you risk sparks, a blown fuse, or damage to either car’s electrical system.
Here are five safe steps to charge a car battery from another car, done the right way.
1. Gather the necessary tools and equipment:
- Before you start charging a dead battery,
- It is important to gather all the necessary tools and equipment.
- You will need a set of jumper cables, a second vehicle with a charged battery, and safety gloves.
If your car still doesn’t start after jumpstarting, especially in Dubai’s heat where batteries wear out faster, it’s usually a sign the battery itself needs replacing rather than another jump. At that point, it’s worth looking into a reliable car battery replacement in Dubai to get back on the road safely.
2. Position the vehicles correctly:
- Park the second vehicle with the charged battery close to the car with the dead battery.
- Ensure both vehicles are in park and that the engines are completely off.
- It is important to ensure that the two vehicles are not touching each other.
- There should be a 3,4 foot gap between the vehicles.
Double-check that both cars are positioned safely and that the area is free from traffic or flammable materials before connecting the cables.
3. Connect the jumper cables:
- First, locate the positive (+) and negative (-) terminals on both batteries
- Then, connect the other end of the red jumper cable to the positive terminal of the charged battery.
- Next, connect the black jumper cable to the negative terminal of the charged battery.
- Finally, connect the other end of the black jumper cable to an unpainted metal surface on the car with the dead battery.
If you ever find yourself in a situation where the car won’t start and no help is nearby, a jump start service in Dubai can be a quick and reliable solution.
4. Start the vehicles:
- Start the charged vehicle’s engine and allow it to run for a few minutes.
- Then, try to start the car with the dead battery.
- If the car starts, let it run for a few minutes to allow the battery to recharge.
- If the car does not start, you may need to wait a bit longer before attempting to start it again.
Tip: Keep the headlights, radio, and AC turned off while jumpstarting; this helps direct maximum power to the battery and improves the chances of a successful start.
5. Disconnect the jumper cables:
- Once the car with the dead battery has started, carefully disconnect the jumper cables in the reverse order that you connected them.
- Start by carefully disconnecting the black jumper cable from the metal surface.
- Then remove the black jumper cable from the charged battery, followed by the red jumper cable.
- Make sure to store the jumper cables properly for future use.
- Let the revived car engine run for at least 15, 20 minutes to allow the alternator to recharge the battery fully.
- It’s also a good idea to schedule a quick battery health check to ensure there are no underlying issues.

FAQs
What order should jumper cables be connected in?
Positive to positive first, then negative to the charged battery, then negative to an unpainted metal surface on the dead car, never directly to its negative terminal.
How long should I let the car run after jumpstarting?
At least 15-20 minutes to give the alternator enough time to properly recharge the battery.
Can jumpstarting damage my car?
Only if the cables are connected in the wrong order or the terminals touch, which can cause sparks or electrical damage.
Why won’t my car start even after jumpstarting?
This usually means the battery itself is too weak to hold a charge and likely needs replacing rather than another jump.
Is it safe to jumpstart a car in the rain or extreme heat?
Rain adds some risk around the connections, and extreme heat means the battery may already be under added strain, so extra caution and gloves are recommended either way.
