Features of a Good Commercial Grade 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.
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.
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.
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.
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.
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.
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.
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.
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.
