Few things are more frustrating than cranking that ignition and hearing nothing. No matter if your trip is to work, a road trip, or simply to do some errands, learning that your vehicle will not start is enough to derail your entire day. In most cases, the reason for this is a dead battery. While this is a common problem, the good news is that you can repair it yourself—if you know how to jump start a car the right way. But what most people do not realize is that improper car battery handling can set you back substantially, both for your car and for you.
It is helpful to learn why a battery would die first and then how to jump-start a vehicle. Car batteries tend to die more in cold weather or if the car has sat for a while. A battery might die because it is simply old, the terminals are rusty, or electrical devices have been left on by accident, e.g., headlights or interior lights that had been left on all night. In other cases, a battery can show dead due to a faulty alternator that is not charging it adequately.
Understanding why your battery died is the secret to proper battery troubleshooting. Jumping a battery but failing to address the root cause will have you in the same situation sooner than you know.
To do a safe dead battery fix, you need the right tools. Most important is a good set of jumper cables. A good jumper cables guide recommends jumper cables with at least six-gauge thickness and long enough to connect vehicles even if they cannot be parked next to one another. If you frequently drive in remote locations, a portable jump starter is also a good investment.
Your owner's manual for your car may also have particular jump starting steps or warnings you need to observe. Take a gander at those before you try anything, particularly if your car has delicate electronics.
Now, let's move on to the actual process of jump starting.
If the vehicle starts, let the engine idle for 15 to 20 minutes to charge the battery.
If the vehicle won't start after a few attempts, pull over and reassess. Maybe the battery is simply too dead to be revived, or maybe the problem lies elsewhere than in the battery. Other possible culprits include a bad starter, a blown fuse, or a more complex electrical issue.
Battery diagnosis is now required at this point. The voltage of the battery can be tested using a multimeter. The voltage of a fully charged battery must be approximately 12.6 volts. A voltage below 12.0 volts means that the battery is extremely drained or damaged.
Also, listen for the sounds the car makes. If you hear a click, that is usually a sign of a battery issue. If the car does not make a sound, then the starter or the ignition switch is likely the issue. These won't start car tips, but they should help you decide your plan of action and whether or not you will need help from a professional.
Once the engine is started, it is necessary to remove the jumper cables in exactly the reverse of the order in which they were hooked up. Begin with the black cable from the grounded metal and then from the negative end of the good battery. Next remove the red cable from the good battery and finally from the revived battery.
Avoid letting the metal clamps touch each other or any part of the car during this process. Mishandling this step can create sparks or cause injury. Just as with connecting them, following these jump starting steps carefully ensures safety and prevents damage to your vehicle’s sensitive electronics.
Jumping a car is only a temporary dead battery fix. If your battery is several years old or has been repeatedly jump started, it may no longer hold a charge. Driving the car at least 20 minutes after a jump gives the alternator a chance to recharge the battery, but have the battery inspected shorty thereafter.
Preventive battery maintenance can avoid problems from occurring in the future. Clean corrosion from the terminals, secure the battery properly, and check the voltage occasionally. Even better, get your car to a garage for a battery load test, which indicates how well the battery can hold a charge under actual operating conditions.
These battery check-up procedures are important for long-term vehicle health and will avoid repeated issues.
An astonishing percentage of drivers are making serious mistakes when attempting to jump start a vehicle. Reversing jumper cable polarity is perhaps the most prevalent error. Attaching the positive clamp to the negative terminal (or vice versa) will result in extensive damage to both vehicles' electrical systems and could even result in battery explosions.
Yet another frequent mistake is skipping the grounding step. Plugging in the final black clamp to the negative terminal of the dead battery directly instead of grounding it on the engine block or metal frame risks sparking—a dangerous action in close proximity to a battery that could be venting gases.
Lastly, never attempt to jump a cracked or frozen battery. In either case, the best tip for a car that won't start is to leave it to the professionals. Working with damaged batteries is risky and should be entrusted to professionals.
The best way to handle a dead battery is not to let it happen in the first place. Drive your car regularly and for long enough trips to keep the battery charged to its limit. If you make lots of small trips or leave your car parked for long periods, keep your battery healthy with a trickle charger.
Also, take notice of warning signs like dim headlights, slow engine cranking, or dashboard alerts. These indicators typically appear before the battery dies completely. Incorporating these battery troubleshooting tips into your normal car maintenance routine can spare you time, money, and effort.
Knowing how to jump start a car is more than a side note on the roadside—it's an important part of being a good driver. It will get you back on the road in a flash if done safely and properly. But it's also useful to know that jump starting is only a band-aid and not a fix for real issues.
By following a step-by-step jumper cables guide, taking the correct jump starting procedures, using effective key car won't start tips, and embracing smart battery troubleshooting techniques, you can get your car running in top condition and never again be left stranded with a dead battery.
The next time your car won't start, don't panic. You possess the skill and knowledge to accomplish the task safely and effectively, without making costly mistakes.
