The DEWALT DXAEC210 professional-grade battery charger and maintainer gets you on the road in minutes when your vehicle won't start or your battery needs maintenance. Connect the powder-coated metal clamps to the battery terminal and press charge; the charger automates the rest by detecting battery type and size. Fully automatic, high-frequency charging delivers 70 continuous amps and 210 amps for engine start, with a three-stage program that switches from fast charge to top-off and then to maintain mode. The LCD screen displays charging status and battery condition with easy-to-understand icons, while reverse polarity protection adds safety. An integrated 120V AC outlet and 3.1A USB port make this charger a mobile power source for tools and devices.
The LCD screen is designed to help you identify issues quickly. If an error code appears, consult the manual for a specific definition. Common indicators include "bad battery," "reverse polarity," and "overheating." For error codes like "bad battery," the charger may be telling you the battery cannot hold a charge or has a shorted cell. In that case, try charging a known-good battery to isolate the problem. If the charger itself is faulty, contact DEWALT support.
Use the DXAEC210 to charge car, truck, SUV, marine, and recreational vehicle batteries. The maintainer mode lets you leave it connected for long-term storage without overcharging. The AC outlet and USB port allow you to power, lights, small appliances, and electronic devices at the job site or in the garage.

Three-stage charging is the safest way to charge modern batteries. The fast charge stage replenishes the bulk of the capacity quickly, the top-off stage brings it to full, and the maintain stage keeps it at the ideal level indefinitely. This reduces the risk of overcharging and extends battery life.
The built-in 120V AC outlet and USB port let you charge your phone, power a work light, or run a small heater directly from your charger. This feature is especially useful during roadside emergencies or remote work sites.
Clean the battery posts and clamps regularly. Check the cable insulation for cracks and the clamps for solid connection. Store the charger in a clean, dry environment to keep it reliable for years.
Error codes on the LCD are designed to guide you. For example, 'reverse polarity' means the clamps are connected incorrectly, while 'bad battery' indicates the battery may have a shorted cell or cannot accept a charge. Refer to the owner's manual for a complete list of codes and recommended actions.
No, the DXAEC210 is designed only for 12-volt batteries. Attempting to charge a 6V battery could damage the battery or the charger.
The reconditioner detects whether a battery can accept a charge. If it detects sulfate build-up on the battery plates, it automatically activates a reconditioning mode that sends pulses of low-current energy to break down sulfate crystals and improve the battery's ability to charge and hold a charge.
Yes, the 3-stage automatic charging system switches to maintain mode after full charge, so you can leave it connected for long-term storage without overcharging.
Yes, the DXAEC210 is equipped with reverse polarity protection, which prevents damage to the charger and battery if the clamps are accidentally connected to the wrong terminals.
Rolls easy, charges fast.
I used the engine start to jump my truck and it worked instantly. The AC outlet is a bonus. Very happy.
I've had this charger for two months and it's been great. The 70-amp charge setting brought my dead tractor battery back to life. The 3-stage charging ensures it doesn't overcharge. The wheels and handle make it easy to move around the shop. The battery clamps are heavy-duty. The AC outlet and USB port are useful additions. I use it at least once a week. Definitely recommend it.
It charges well. It's just too heavy to lug up stairs. But it's on wheels, so okay.
Plug in, select the rate, it does the rest. No issues.
I use it for my RV batteries. It keeps them topped off. The digital readout is clear.
This charges my golf cart batteries much faster than my old charger. Impressed.
The fan is a bit noisy, but it's a powerful charger. I can live with it.
It does what it says. But it takes up a lot of space.
