What to Consider Before Buying Commercial Battery Charger

 As a mechanic, there are several key considerations to take before you buy a commercial battery charger. A commercial battery charger should be able to charge different types and sizes of batteries. Here are some features you should look for when setting for an industrial car battery charger:

heavy duty battery charger for trucks

Charging Voltage Output

Before you settle on the charge voltage settings of the battery charger, it is important to consider your commercial requirements. Lower voltage battery chargers work on small vehicles but if you will most likely deal with heavy and large vehicles you will need high a voltage battery charger. Most of the

Most of the best battery chargers have a voltage output of 12V and this will work on almost all vehicles. However, a 24V heavy equipment battery charger charges a wider variety of vehicles from golf carts to large trucks. Some other battery chargers have a 6V output and they are more ideal for standard vehicles.

Charging Current

Another Crucial thing to check is the charging current of the battery charger. You want a unit for commercial purposes thus it is advisable to consider one with a higher current. Battery chargers with higher current charge faster than those with a low current rating. Some units feature a single charge output of up to 100A.

This means that they can charge 100Ah batteries in slightly over an hour. Slower charging on the other hand is safe and it prevents damage to the batteries and overcharging. The most prudent thing is to get a battery charger that offers both slow and fast charging options.

Quality of Clamps

Clamps are what connect the battery charger to the car battery terminals. Build-up and corrosion on battery terminals make charging quite difficult. The clamps of the battery charger should be able to handle this.

Ensure the clamps of your battery charger are high quality with high tension springs. This feature helps the clamps to bite through the buildup on the terminals and offer a good connection for maximum transfer of charging current.

Charging Modes

Today there are many types of batteries which include lithium, maintenance-free, marine, AGM, and deep-cycle among others. These batteries differ in their internal chemistries and have other fundamental differences which mean that they need specific charging modes.

This is something you need to consider when buying a battery charger for commercial purposes. Consider a battery charger featuring multiple charging modes to comfortably cater to the various batteries in commercial applications.

High Build Quality

If you want a unit that will last then it has to be made from high-quality materials. We all know that in a workshop environment, knocks and bumps are inevitable. There I also probable exposure to corrosive liquids and grease and it should be able to withstand this. A good commercial battery charger is made of a tough outer casing that withstands even the most unfriendly environments.

In-Built Battery Testing

At times the battery does not need to be charged but rather requires replacements. It would be advisable to buy a battery charger with the ability to test if the battery is fully damaged and needs replacing. Having this in the charger will save you money from buying a full-fledged battery tester.


Most heavy-duty battery chargers tend to be quite heavy. In most commercial applications, you might be required to move the unit from one place to another. Some of the best commercial car battery chargers have wheels and a comfortable handle to make movement around the workshop easy.

Safety Features

You cannot afford to overlook the safety features of a battery charger. This unit has high output currents and it should have features preventing the damage to itself, the batteries, and the people handling it. The most important features include overcharge and overheat protection, short circuit, and reverse polarity.

Jump-Starting Assistance

This feature diversifies the work of the unit. Some of the units with this feature allow you to jump-start your vehicle directly from the battery charger. This is an important feature, especially when looking for the reasons for a dead battery before you start charging it.


Do Deep Cycle Batteries Need Special Chargers?

Deep cycle batteries should be charged with some special charger types which keep them healthy. Using a traditional battery charger on this type of battery does not give you the best results.

This is due to the reason that whenever a battery is charging, excess heat is produced. Deep cycle batteries are not made to handle extra heat or rapid charging and thus they will not reach their full capacity.

Can You Overcharge a Deep Cycle Battery?

Overcharging a deep-cycle battery leads to overheating. The thermal runaway reduces the battery life and also causes grid corrosion. The excessive heat produced from overcharging causes the cells to clasp thus shedding their active material. A deep cycle battery will fully charge in approximately 2 hours when using a 15 amps charger and around 6 hours using a 5 amps charger.

How Long Do You Charge a Deep Cycle Battery?

The length of time you use to charge a deep cycle battery will depend on its size and also the type of charger you are using. Assuming you are charging a normal deep cycle battery with a standard charger, then it would take 12 to 16 hours.

What Is the Best Heavy Duty Battery Charger?

The best heavy-duty battery charger will depend on your needs. If of cause need to have a high voltage output to enable it to charge large size batteries. These batteries are mostly used in a workshop and thus they need to have a high-quality build to withstand the harsh environment.

Another feature is high charging outputs to enable it to charge heavy-duty batteries in less time. Most of the battery chargers discussed above can work in this situation but Associated Equipments 6002B works perfectly on heavy-duty applications.

Who Makes the Best 12v Battery Charger?

There are several 12v battery chargers and you may wonder which brand is the best. The first thing you need to know is that different battery charger brands come with different features ideal for various applications.

The choice you make should depend on if it is within your budget and if the features meet your needs. Some of the most outstanding brands for 12v battery chargers are Associated, Renogy, Battery Tender DEWALT, and Schumacher.

How Long Does It Take to Charge a 12 Volt Car Battery?

The amount of time you will take to charge a 12-volt car battery will depend on the amp rate. When using a 10 amp battery charger, it will take around 4.5 hours. When using a 15 amp charger, it will take approximately 3.6 hours. If the battery charger has more charging output, it will take a shorter time.

Final words:

With the best commercial battery chargers discussed above, you can never go wrong. Since the battery is for commercial use, you should buy one that will cover a wide range of batteries as possible. In this case, the battery should have a high voltage output and high charging output.

On top of this, a good commercial battery should be built with strong and high-quality materials that will make it last longer even when used in harsh environments. The most important thing is to understand the needs of your industry and get the right match for those applications.
