Understanding Car Battery Chargers & Jump Starters

The jump starter and battery charger provide two different services. A typical jump starter gives the vehicle a quick jump, allowing the battery to turn over. From there, the alternator takes over and charges the battery while driving. On the other hand, a battery charger recharges the battery.

You can leave it attached to the battery for a specified amount of time to ensure the battery gets the power it requires. While you can purchase these two models separately, there are also plenty of portable car battery charger jump starter products that incorporate both features.


How to Test a Car Battery Charger/Jump Starter

It's not difficult to test your battery charger and ensure proper operation.

  1. 1
    Plug the charger in and disconnect it from any batteries it is charging.
  2. 2
    Turn on the voltmeter and ensure the settings are correct.
  3. 3
    You can place the probes of your voltmeter onto the appropriate charging cables to ensure there is enough power supplied to charge the batteries.

If there is enough power, but the battery is not charging, it could be that it requires replacement. The battery holds a charge, even when it's not in use. However, this time depends on what type of battery you have. If it seems that the battery isn't providing the life you would expect, consider battery reconditioning before replacement.


How to Safely Use a Car Battery Charger & Jump Starter

To charge a car battery with the best portable charger, you would follow these steps.

  1. 1
    Plug in the charger.
  2. 2
    Hook the positive cable to the positive battery terminal.
  3. 3
    Hook the negative cable to the negative battery terminal. Don't allow the positive and negative cable to come in contact at any time.
  4. 4
    Set your charger to the slowest charging rate.
  5. 5
    Turn on your charger and set the timer.

If the voltage of the battery is below 11.85 and the charger puts out a 5-amp charging rate, it should take about 12 hours to charge the battery with 400 to 500 cold-cranking amps. This same battery would only take six hours to charge if the rate was upped to ten amps.

Here is an example of how to hook up the battery charger.

If you have a dead battery, you will need to use a jump starter instead. Here are some simple directions to follow.

  1. 1
    Turn the car off.
  2. 2
    Plug the jump starter in, but leave it in the OFF position.
  3. 3
    Connect the red clamp to the positive terminal.
  4. 4
    Connect the black clamp to the negative terminal. Don't allow the clamps to touch.
  5. 5
    Turn on the portable jump starter.
  6. 6
    Attempt to start the vehicle. Don't crank the engine for over five seconds. If it doesn't immediately turn on, wait a few minutes, and try again.
  7. 7
    Once the vehicle starts, you can remove the jump starter. Allow the vehicle to run and charge the battery.
