Tips Before You Purchase

Choosing an automotive battery charger isn’t a walk in the park. You have to use a few hacks.

You must be sure that the type of battery charger you choose is compatible with your battery. Otherwise, you may end up with a damaged battery. The best battery charger must also be within your price range. Likewise, it has to save your time, both when it’s getting recharged and when it’s charging your car battery. A portable car charger is often preferable. It will be even better if you found a battery trickle charger. One that can jump-start your car is another windfall.

Q: How To Charge A Car Battery?

A: When the voltage drops past 12 volts (if it’s rated 12V), your car battery can get recharged. It is at this point that you’ll get the right recharger and start the charging process.

  1. Locate your car battery’s positive and negative terminals
  2. Before switching it on, attach the red clamp of your charger to the positive terminal of your battery, and the black one to the negative side. Please mark these colors.
  3. Then, switch your charger on. Some chargers have an on/off button for cars, and others for motorcycles. Make sure that you switch the right one.
  4. Leave your battery to charge for the recommended time, then unplug or switch off the charger.

Q: How Long Does It Take To Charge A Car Battery?

A: The answer depends on a lot of factors, mainly, the amp charge rate, and the battery’s amperage. Most batteries are 48 amps, so with a standard 4 amp charge rate, it’ll take 12 hours. If you use a 1 amp charger, it’ll take 48 hours. You can always do the mathematics.

Q: How To Connect A Car Battery?

A: Follow below steps

  1. Make sure the engine is off.
  2. Use baking soda or other battery cleaners and water to clean the battery tray. Also, clean the hold-down clamp.
  3. Use a wire brush and solution used above to clean the cable connectors, too.
  4. Insert your new battery into the tray, and secure it using the clamps.
  5. Clean your battery’s terminals, too.
  6. Connect the positive cable firmly. Do the same to the negative one.
  7. Check if the battery is firmly held and tighten further if there’s a need.

Q: How To Put A Battery In A Car?

A: While inserting a new battery in a car, the following rules are inevitable;

  1. Insert the new battery in the exact posture as the old one.
  2. Always connect the positive cable prior to the negative cable.

Q: How To Charge A Car Battery Without a Charger?

A: This is only possible with jumper cables and a good Samaritan. I’ve described the jump-starting process above.

Q: How To Hook Up A Car Battery?

A: A car battery charger should be hooked up using battery clippers. The red clipper should always connect with the positive terminal. The black clipper is meant for the negative terminal. It’s always important to clip the red one before the black one.

A: At home, you may have all the charging devices that you need. You may have a portable charger, a small battery charger, an advanced auto battery charger, and more. Whichever the one it is, just use it the right way, as described above.

Q: How To Tell Positive And Negative On A Car Battery?

A: Always, each terminal of your battery will have positive (+) and negative (-) marks appropriately. If the marks are missing, there’ll be color marks, where red means positive and black means negative.

Q: How Long To Charge A Dead Car Battery?

A: The charging duration depends on the type of charger used and your battery’s capacity. On average, with a charging rate of 4 amps, you’ll only need one hour for a 52-amp battery to start the car, and 10 hours to charge until it gets full. However, with a heavy-duty battery charger, this will take a shorter time.

Q: How Much Is A Portable Charger?

A: Portable chargers aren’t the same. The price depends on the features of the charger and its significance. For example, you won’t expect a manual battery charger and a smart battery charger to have the same price. At the same time, a 200 amp battery charger won’t have the same price as a 100 amp model. Generally, the chargers have prices ranging from $17 to as much as a whopping $400! The common 12v car battery charger ranges between $30 to $300.

Q: How To Charge A Car Battery With Another Car?

A: It’s possible if you never knew, and the process is dubbed jump-starting. You need the best portable car jump starter for this. Here are the steps.

  1. Ensure that both vehicles (donor and recipient) are off. They should be in the parking mode.
  2. Check if both batteries have the same voltage. If yes, you’re safe.
  3. Connect the jumper cable’s positive cord to the donor’s positive terminal. Do the same to the receiver’s.
  4. Connect the jumper’s negative side to the donor’s negative terminal and do the same to the empty battery’s negative terminal.
  5. Leave them connected for about ten minutes, and start the once-empty car. Of it doesn’t start, the battery is faulty, and it needs a repair.
