How To Choose The Best Car Battery Charger

How To Choose The Best Car Battery Charger

As mentioned earlier, the ‘best’ battery charger is one that satisfies your current situation, so when shopping for the product here are a few things you need to keep in mind.

1. Battery Size and Voltage

When buying a battery charger, make sure its output voltage is the same as that of your battery. Any difference in voltage will not only have an effect on the charging but could also cause permanent damage to your battery. Plus, you should select one according to the type of vehicle you own, i.e. car or truck. After all, the size of the vehicle determines the size of the battery, and hence the power capacity of the charger you need. Common inexpensive car battery chargers for home use generally handle 12 Volts and in some instances 6 Volts too.

2. Battery Chemistry

Almost all car batteries are lead-acid, consisting of lead plates in an acid solution. The difference in chemistries comes from the difference in their composition, i.e. whether they are standard lead-acid, Deep Cycle or AGM, or Gel Cell. You do not necessarily need to remember all the details about the chemistries, but you should know the type. Keep in mind that not all chargers can handle the unique needs of Gel Cell, AGM or Deep Cycle batteries since most cater to standard lead-acid.

3. Manual or Automatic

Car battery chargers can be automatic or manual. The majority are automatic, which means they can detect that the battery is fully charged and automatically switch to a float mode or trickle charge to prevent it from overcharging. You should definitely opt for a charger that offers this feature.

4. Microprocessor Control

This is where a microprocessor is attached to the charger that can regulate the whole charging process based on the charger’s feedback and the battery itself. Many modern chargers are microprocessor controlled and they have additional options for recovering or conditioning batteries and offer finer control over the charging procedure, thus enhancing charging performance.

5. Ease of Use

It is important to invest in an easy to use charger. If you are looking to avoid technicalities, definitely go for a fully automatic charger with minimal adjustment. If you own multiple vehicles (with different battery types), you need to invest in a complex but capable charger with selections for charging rate, output voltage, and battery chemistry. Car battery chargers can be light or heavy, small or large, and bulky or portable. If you are looking for a large charger, make sure it has handles for added convenience and portability.

Charging A Car Battery With A Battery Charger

Charging A Car Battery With A Battery Charger

1. Connect The Charger

  • Make sure the charger is off
  • Connect the positive (red) battery terminal with the positive cable on the charger.
  • Connect the negative (black) battery terminal with the negative cable on the charger.
  • Set the charger to its lowest charge rate

2. Set The Charger

Once you have connected the charger, set the amps and volts. If you want to slowly trickle charge the battery, set the amperage to a lower setting as compared to when you want to start your car quickly. If you have time, always go for trickle charging since it does a better job at charging your battery. However, if you are in a hurry, set your charger to high amperage.

3. Plug In And Charge

Plug the charger in and go about your business. You may have the option to set a specific amount of time for the charger to work, or it may automatically shut off when the charge is complete. Either way, it is a bad idea to play with the cord or move the charger during the procedure.

4. Disconnect

After the battery is fully charged, you can turn off the charger and remove it from the outlet. Disconnect the cables in the opposite order in which you connected them: negative clamp first, positive clamp second. Your battery should be fully charged by this point and you should be ready to go.

Safety Tip: When charging your car battery, always wear protective gloves and safety goggles. In addition, there is always a risk of the battery exploding when recharging, so make sure you follow the appropriate battery maintenance and safety protocols.

How Long Does A Battery Take To Charge Completely?

If the battery voltage is less than 11.85 and your charger is on a 5-amp charge rate, it will take approximately twelve hours for a battery with 400 to 500 cold cranking amps to charge fully. That same battery will require around six hours to charge completely when the amp rate is 10. The time required for a battery to charge completely depends on the open circuit voltage and the number of cold cranking amps. Remember that if a cell is malfunctioning, the battery will fail to charge at all. In this case, take your battery to the local mechanic who will know the best possible solution to the problem at hand.
