How to Use a Car Battery Charger

Car Battery Charger


There are few things more frustrating than discovering your vehicle has a dead battery while out and about in Omaha. When you have another driver around, you can give your car a jump. If not, it’s handy to know how to use a car battery charger. Car battery chargers come in several different varieties. There are options that help maintain stored vehicles and portable car battery chargers to help in a pinch when you’re stranded in Lincoln. Review our service tips below to learn how long to charge a car battery and more today!

 

 

What Are the Types of Car Battery Chargers?

When it comes to car battery chargers, there are three main types: charger, maintainer, and restorer:

  • Charger: In most cases, chargers use a low-amp charge to power up your battery in 24 hours or less, though the time can vary based on output. You can also find portable car battery chargers to keep on hand for those Blair road trips. Whenever you use a car battery charger, keep an eye on the charge level to avoid causing damage.
  • Maintainer: As you might have guessed from the name, battery maintainers keep tabs on the charge level of a vehicle. This is a great option if you’d like to provide a continuous charge without overdoing it. You can even find solar-powered maintainers to help keep your vehicle charged in an eco-friendly way!
  • Restorer: Over time, car batteries formulate lead sulfate crystals when they run low on charge. This build-up prevents the battery from gaining a full charge ever again. With a restorer, you can prevent this build-up and extend the lifespan of your battery. A restorer will detect battery sulfation and use a desulfator to restore the battery.

Important Note: If you find yourself using a car battery charger on a consistent basis, you likely have a larger issue that needs to be addressed.

How to Use a Car Battery Charger

To learn how to use a car battery charger, first turn off the charger, then follow the instructions below:

  • Attach the charger’s positive cable to the battery’s positive terminal.
  • Attach the charger’s negative cable to the battery’s negative terminal.
  • Adjust the charger to its slowest charge rate.
  • Then, power on the charger and set a timer.
  • When you’re ready to disconnect the charger, make sure it’s off first.
  • Then, detach the cables.

How Long to Charge a Car Battery

So, how long should you charge a car battery? This depends on the output of the charger and the status of the battery itself. If the battery voltage is 11.85 or less, and you have a charger that supplies a 5-amp charger rate, it’ll take about 12 hours to power up your battery. If the charger can put out 10 amps, the charge time drops to 6 hours. These time estimates are based on car batteries with 400-500 cold-cranking amps, as the number of cold-cranking amps and the battery’s voltage will impact charge times.
