How to Charge a Battery

This is our guide on how to use a car battery charger in the simplest sense when you have a dead battery in Moorestown:

  • 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.

However, if the instructions for your charger differ from this, it’s best to go with what you see on the page.

How Long to Charge a Car Battery

The answer to this question really depends on the output of the charger, in addition to the condition of your car battery. If the voltage of the battery is less than 11.85 volts and you have a charger that gives 5 amps of charge rate, you’ll have a full battery in roughly 12 hours. If the charge rate of the charger is 10 amps, you’ll have about 6 hours to fully charge the battery. These are estimates for car batteries with 400-500 cold-cranking amps. The number of cold-cranking amps and the battery’s voltage will impact your charging time.
