Pros And Cons Of Using A Battery Charger Instead Of Jump Leads

  • You don’t need anyone’s help. Sometimes flagging down a passing motorist doesn’t work, and waiting for a friend or family member to come give you a jump costs time.
  • You get going a lot faster. Aside from the time you save doing things yourself, battery chargers are also more efficient. You don’t have to wait five to ten minutes while the two cars idle to charge your battery enough to start the vehicle.
  • They are far more expensive than a set of jumper cables. This is especially true if you opt for the higher output options. Time really does mean money.
  • They’re useless unless charged. If you don’t remember to recharge the battery packs after use, you might still find yourself stranded and relying on others.

Test Your Battery And Charging System


You can check the condition of the battery, starting and entire charging system with a computerized battery tester. One choice is the SOLAR BA9, available from Amazon com. Besides testing voltage, it tests internal resistance and the condition of the starter and alternator. This one works on conventional SLI batteries, as well as gel and absorbed glass mat , so you can also use it on motorcycle and lawn and garden equipment.

How Long Should You Run Your Car After A Jump Start

You have successfully learned how to jump start a car with a portable power pack. One commonly asked question once you have your engine running is, how long should you run your car after a jump start to recharge the battery?

You should understand that you will be relying on the alternator in your car to provide charge to your battery while the engine is running.

The job of the alternator is to provide only a small charge to your battery. This small charge should be enough to keep your battery topped up to a full charge.

The alternator is not designed to, and should not be used to fully charge a flat car battery.

Charging a flat car battery back to full health by running your car could take around 5 hours. The best way to charge a car battery would be to get your car home and use a dedicated car battery charger or trickle charger.

Read our How To Change A Car Battery guide, and our How To Charge A Car Battery At Home guide. You will learn everything that you need to know about charging your car battery at home.

Keep The Following In Your Car At All Times:

  • Jumper Cables: The longer, the better!
  • Mechanic Gloves: Disposable gloves at the very least, but heavy duty offers more protection
  • A Flashlight: Always handy to keep in your car!
  • Paper Coveralls: Protection for your clothes paint stores usually carry these
  • Owners Manual: You can often find this in your cars glovebox
  • To jump start your car, you will need to find someone with a vehicle to provide the jump to your dead battery. It is important to be safe and use sound judgment when seeking assistance from people you dont know. Dont accept help from anyone you dont feel comfortable around, and be sure to phone a loved one to let them know exactly where you are and whats going on.

    6. Adjust the voltage on the charger. If unsure, consult with the owners manual for the best results. A slow, or trickle charge, will usually give you better results.

    What Voltage Does My Car Battery Have To Be To Start My Car

    Despite the fact that your car battery is labeled as being 12 volts, that does not mean that it is charged when a reading of it indicated 12 volts. If that were the case, a 12-volt reading would mean that your battery was only about 45% charged and would likely not be able to start your car.

    Your car battery should ideally have a voltage reading of 12.6-12.7+ when at rest. A reading in this range would indicate a charge of 95-100%. When you start to get around 12.1 it starts to become a coin toss of whether or not it will turn over when you crank the key.

    How To Charge A Car Battery At Home

    In winter, when its cold outdoors, its better to bring the battery in. However, it extracts harmful gas, so the premises are to be properly ventilated. Anyway, I would recommend charging a battery in a garage that is heated and illuminated, rather than at home. The process is the same as it was described above. The terminals and case cleaning, the charger hooking up and turning on, the timer setting is the basic stages. The charger is to be off during the cables connection.

    But, how to charge a battery without a charger? You can do it with a common, laptop charging device, adding copper wires, a bulb, and a resistor. Connect the wires, checking the scheme, positive, and negative separately. However, you are to be an electrical engineer to apply this method, as its a bit complicated and dangerous.

    When Do You Need To Buy A New Battery

    If your battery is running dead time and time again, youre putting a lot of stress on the ignition and alternator youre also risking power surges during recharge that could fry your electronics, fuses, and even bust bulbs in the headlights. The simplest way to tell if your battery is toast is to use a voltmeter when the car is running and being revved to see what kind of output youre getting. The reading on a voltmeter should be between 13.5 and 14.4 volts, any lower and its replacement time.

    Your battery is easy to replace you should never let it get to be such a problem that youre parking beside cars with drivers who look nice enough to lend a charge each time you go to the store. Not only is it an inconvenience, but youre also risking damage and wear to other parts as well. Once your battery has died, check it with a voltmeter after you get your car running again.

    What Other Portable Jump Starter Features Do I Need To Look For

    Many portable jump starters come with additional features, but the issue is size and weight. Add all of the features in one unit and the jump starter gets much bulkier, with weight exceeding 30 pounds. For some purposes — camping trips for example — that may not matter much. On the other hand, you may not want to be carrying one of the bigger portable car batteries around in your Mazda Miata. Some manufacturers, including the highly rated Antigravity brand, are starting to offer separate accessories like a small, powerful air compressor that work with their paperback-size lithium-polymer jump starter batteries, but this approach tends to add to the cost.

    Dead Car Battery Tricks

    How to jump start a dead car using battery charger

    Meanwhile, when a force majeure situation already happened, and the battery is dead, its still possible to revive it. Youll diagnose that its dying when the dome light and headlights are dim, the motor doesnt start, the radio doesnt turn on after the ignition switch is turned.

    In this case, you can:

    • jumpstart the car with another vehicle, battery booster or another accumulator
    • add electrolyte
    • give it a dose of aspirin, soda or magnesium sulfate .

    Adding some chemical compound to the water, you make the acid mix stronger. However, please, be careful with a frozen battery, as it can explode. It is to be thawed before recharging.

    Using A Car Jump Starter With A Hybrid

    If you drive a hybrid, it’s typically safe to use a car jump starter or a regular jump-start on the auxiliary battery. These auxiliary batteries are nominally 12V, just like regular car batteries, but they’re typically smaller.

    The main danger associated with hybrids and jump-starting is that if you use the auxiliary battery in your hybrid to jump someone else’s car, you may end up depleting it to the point where your vehicle won’t start. It is safe to use a jump starter or portable power pack on that type of battery.

    The other type of battery contained in most hybrids uses a different, much higher voltage than the 12V used by conventional cars and trucks. You can’t jump-start the main batteries in your hybrid with a car jump starter or jumper cables and another car.

    If you drive an electric car, never attempt to provide or receive a jump-start. Electric cars are meant to be charged in a specific manner.
