Turning the key to any vehicle and finding a dead battery is not a desirable situation. However, with the right amount of foresight and the right equipment, this situation can be avoided.

A commercial battery charger is a powerful device characterized by enough strength to charge a fleet of vehicles, vehicles in need of repair, dealership vehicles, construction equipment, and then some. It is commonly used in service repair shops, industrial outlets, and dealerships. Choosing the right battery charger means seeking the ideal combination of powerful performance and versatility.


Features of a Good Charger

There are quite a few different commercial battery charger options on the market. Choosing the right one means understanding the charging needs of the vehicles in question and the desired industrial usage. There are different features to be considered in order to make the right choice and investment.

Starting Assist

Some models have a start assist. This is useful if time is of the essence. The start assist powers up the vehicle without waiting for a full capacity battery charge. This is not standard on all models, so look out for it as an option. Check charger specifications to ensure it is equipped to start 6V and 12V batteries.

Easy Transport

The charger has a large job, so it makes sense it is a large device. But this also means a powerful charger will be heavy. Hauling it from one vehicle to the next will quickly become draining. This is why checking for added wheels and handle will make using it easier. Wheels are essential if the charger needs to be transported.

Battery Testing

Of course, sometimes it is not a question of charging the battery but rather of replacing it entirely. Some charging systems have the capability to detect if the battery is bad or unable to accept a charge. It will let you know when charging time really needs to be replacement time.

Output Voltage

Battery voltage varies within different industries. It is possible to be working with 6V or 12V batteries, or both. Purchasing a charger means determining its capability of handling necessary battery voltages.

Continuous Charging Amps

The basic car charger runs at about two amps. This will take 24 hours to deliver the 48 amps required to charge the typical 48-amp hour battery. Since there is a wide range of battery chargers, all providing various levels of continuous charging amps, you want to choose one with a higher output if you want to spend less time charging.

Crank Assist

If you don’t want to wait for charging, you want a model that features crank assist. This allows you to receive the juice needed to get started without waiting for a full capacity charge. Not every unit comes with this function, but most commercial units do. Just pay attention to the specifications to make sure you get what you need.

Durability

Battery chargers don’t respond well to heat, which is why a high-quality commercial battery charger will include a powerful cooling mechanism that prevents overheating. If you want the heavy-duty battery charger to last as long as possible, you want to pay attention to what integrated fan is incorporated into the design.

Safety Features

A professional battery charger doesn’t just provide plenty of power, but can also be dangerous. If you find a unit with insulated alligator spring clamps, you have more protection from shock. You also want to look for reverse polarity detection, which lets you know if the clamps were incorrectly attached. Finally, make sure you examine the commercial truck battery charger for CSA/UL testing certification.

Summary


Battery Charger Power and Versatility

The power aspect means the charger can go from vehicle to vehicle and provide quick and reliable charging. Power is measured through the charging amps rating. This rating gives an idea of the rate the charger will be able to charge the battery.

Desired ampere units will vary based on the needs. Chargers featuring 30 or 60 charging amps can be easily found. The higher level of amps translates to faster charging time, especially when compared to the typical 10-amp battery chargers available to consumers. Versatility pertains to the ability to charge different sizes and types of vehicles. Versatility is key because it means one purchase versus needing several battery chargers to address all vehicular needs.


Battery Reconditioning

One of the ways you can get the most out of your battery charger is to use it while reconditioning batteries. The money you save doing this instead of buying new batteries will help pay for a new charger in no time.


Charging a Dead Car Battery

Before you charge a dead car battery, you must take some safety precautions. Place the charger as far from the vehicle as possible. Remember to always use the red jumper first and make sure you don’t touch the clamps while the charger is on. Then, you want to select the right setting for the vehicle you are working on. The crank assist setting is simply used to jump-start a battery.

  1. 1
    Clip the red cable to the positive side.
  2. 2
    Attach the black cable to the negative side.
  3. 3
    Connect the charger to a power source.
  4. 4
    Allow the battery to charge fully before using it.
  5. 5
    Unplug the device from the power source and disconnect it in reverse order.

Commercial Battery Charger: Care & Maintenance

Whenever you work with commercial batteries and chargers, you must take special steps to maintain your equipment. Before use, you should always check the cables and connectors on your commercial battery chargers for cars. Look for any signs of wear or damage. If you notice something isn’t right, don’t use the charger. After use, make sure you wipe off any dirt or debris and store it in a cool, dry environment.


Frequently Asked Questions

How long does it take to charge a car battery with a commercial battery charger?

If you jump-start the vehicle, you can rely on the alternator to charge it as you drive. It would take about an hour to achieve a full charge this way. By using a battery charger, you will need more time, but it all depends on the amperage put out by the commercial-grade battery charger.

Can I leave my car battery charging overnight? What happens if I overcharge my car battery?

You might damage the battery if you leave it continuously connected. If you plan to leave it on for a long time, you want a system that has an intelligent charger and automatically switches to a maintenance mode once it is charged.

What are the differences between an automatic and manual battery charger?

The manual battery charger requires input from you as the battery charges. You will need to remove it once the battery is fully charged, where an automatic charger knows when to switch to a maintenance mode and lessen the chance of damage.

How long do these commercial heavy duty battery chargers last?

Depending on which model you purchase, you can expect many years out of the best heavy-duty battery charger. Obviously, you want to buy a unit from a reputable manufacturer that has positive reviews and an included warranty.

Can you use a car battery charger on a marine battery?

No, the car battery charger doesn’t have the power you need on trickle charge. What you need for deep cycle marine batteries is ten amps instead.

How do you test a commercial battery charger?

If you aren’t sure if the battery charger is working, you can use your voltmeter to determine if it has enough power.


Conclusion

For the majority of shops, it makes sense to purchase the Battery Tender 5-Bank . Of course, if you work on large semis, you will want a truck battery charger instead. In that case, look for the best 24-volt battery charger, such as the Solar TCB-HT1224
