Jump-starting a Battery Simple step-by-step Tips

Your morning started on a great note: a warm cup of coffee and about ten minutes of revising your big presentation. You’re more than ready to start, but unfortunately, your vehicle isn’t. Even after you’ve turned the key and pumped the accelerator pedal in vain for the last ten minutes, it just won’t start. All your efforts seem to fail, and your other half has already left for work – what now? All you need is a helpful Samaritan nearby and some handy tips from Women-Torque to see you through this task.

Firstly, it’s good to know that the size of your battery doesn’t matter in this scenario. All that matters is that both your battery, and that of the battery you’re going to use to jump-start your own are similar in voltage and amperage. This actually makes sense, as you are ‘transferring’ a certain amount of ‘power’ from one battery to the next. If you jump-start a vehicle where the batteries are too different in voltage, there will either not be enough power to start yours, or it may overload and cause damage.

Let’s begin: - Get your hands on jumper cables. Important tip: make a point of buying a set and keeping it in your car boot.
- Position the vehicles within reach of each other (battery side to battery side so the cables can reach) and make sure both are in neutral or park, with the ignition shut off.
- Determine the negative and positive terminals – it will generally be indicated by ‘+’ for the positive terminal and a ‘-‘ for the negative terminal on the battery. If not marked or colour-coded in red and black, the positive terminal will be slightly bigger than the negative terminal.
- Briefly wipe the terminals of both batteries with a rag or clean cloth, if possible.
- Starting with the dead battery, attach a red (positive) clamp to the appropriate terminal, and then attach the other end of the red (positive) cable to the Samaritan’s battery.
- Once the red clamps are secured, position the black clamp on the black (negative) terminal of the Samaritan’s battery. Place the other black clamp on your vehicles bonnet support rod, or any unpainted metal piece that the black clamp can clip onto, away from your battery. The reason for this is that it ensures a safer jump, because the chances of a danger of a sudden spark and explosion is lessened.
- Ask the Samaritan to start their vehicle, and after this is done, test whether yours starts. If your car doesn’t spring to life, double-check all connections, and run the Samaritan’s car for another five minutes. If you still do not have enough power to start, you’d better call a professional. We’re confident you should be sorted, in most cases, however.
- Now, you can safely remove the jumper-clamps from both batteries: first remove the black clip from the bonnet support rod or unpainted metal piece on your vehicle, and then the corresponding end of the black cable from the other vehicle. Lastly, unclip the red clamp from the donor battery, and then the clamp from your red terminal.

Simple as that! Remember that if you’ve had a flat battery situation like this, ensure to run your vehicle for a solid fifteen minutes before shutting off the engine, as the battery needs time to recharge. Kick-’start’ your independence today – make sure you have jumper cables and this guide on hand in case you ever need it.
