If you’re looking for a 12V battery charger to service repair shop, fleet, industrial, or auto dealership requirements, you need a heavy duty battery charger.  Not only that, but because you’ll probably have to lug the charger to the battery that needs charging, you should pick a wheeled model that will make the job much faster and easier.

You can buy a heavy duty battery charger with a variety of capabilities depending on the range of situations that it will be required to handle.


One thing that is definitely true of fleet and industrial work is that time is money.  That means that whatever equipment needs the dead battery, if it’s out of operation, it’s costing you money.  To achieve faster charge times, you need a heavy duty battery charger that produces a lot of power.  Chargers with 30 and 60 charging amps are not uncommon and will charge batteries much faster than a typical 10-amp consumer car battery charger.

Heavy Duty Battery Charger Fleet TrucksStarting Assist

Sometimes the battery just needs an assist in order to start a vehicle.  For that, many industrial battery chargers come with a starting mode which provides the additional amperage that starting requires.  If you will have to start equipment with both 6V and 12V batteries, make sure the charger you buy is equipped to handle both.

Load Testing

If you appear to have a battery problem, it may not be immediately apparent whether it’s a problem with the battery or a problem with the charging system.  Some models come with testing capability to determine if the battery is bad and unable to accept a charge or if the charging system is faulty and is not producing a charge.

Heavy Duty Battery Charger Car DealershipManual or Automatic

Most heavy duty commercial battery chargers are manual operation.  That’s because they are not designed to be trickle chargers, battery tenders, or battery maintainers which have built-in microprocessors that are left connected to a battery to maintain its charge during long periods of inactivity.  Rather, fleet battery chargers are designed to connect to a battery, quickly recharge it, and then are wheeled to the next problem.  Eliminating the complexity of microprocessor control also reduces cost.

Output Voltage

Depending on your industry, you may see both 6V and 12V batteries.  With that in mind, make sure that the battery charger you buy is capable of handling both battery voltages.
