Prepping the Car Battery Charger

If your vehicle’s battery still has a little juice left, it’s probable that a charge from the charger will have it up and running again. Before you get started, check to make sure you can (or can’t) charge the battery as it sits in the battery tray – you may need to remove the battery to charge it if there’s not enough room for the charger to safely rest.

How to Charge a Battery

Start by making sure the charger is off, then follow these instructions (or the instructions that come with your charger):

  • 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 lowest 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

How long to charge a car battery will vary based on a number of factors including the battery size and the output of the charger itself. Learn more about how to use a car battery charger here:

Charge Time Example:

If the voltage of the battery is less than 11.85, and you have a charger that supplies a 5-amp charger rate, it’ll take about 12 hours to fully charge your battery. If the charge rate of the charger is 10 amps, however, it’ll take about 6 hours to fully charge the battery. Those time estimates are for car batteries with 400-500 cold-cranking amps.

What Are the Types of Car Battery Chargers?

There are essentially three main kinds of car battery chargers. There are regular chargers, maintainers, and what are known as restorers as well. Each kind of battery charger serves a specific function, as you’ll note below:

  • Standard Charger: A standard charger most often uses a low-amperage charge to fully recharge a car battery in anywhere from 2 to 24 hours, depending on charging and battery factors. When using one of these chargers, keep an eye on the battery to ensure that it does not overcharge and cause damage to the battery.
  • Maintainer: As the name suggests, maintainers keep charging the battery until it has reached a full charge, then maintain that charge with a trickle of low-amp electricity. These are excellent for providing constant power without overcharging or overheating the battery.
  • Restorer: Last but not least, a restorer is a type of charger used to desulfate batteries with a large buildup of lead sulfate crystals. Not only do they help keep a battery fresh, but they can also be used for charging in most cases as well!
