This DEWALT DXAEC2 Professional 2-Amp Automotive Battery Charger and Maintainer appears to be a basic float charger. Once the battery voltage goes below the float voltage of about 12.85 V, the yellow charging light comes on, and it charges at up to 14.25-15.0 V, about the same as a car alternator (see updated details below). It only gets slightly warm if charging for a long period, otherwise is cool. Doesn't seem to vary the voltage with temperature. I now have two of these. The one has an observed float voltage of 12.90, and the other 12.83. I've had the one outside under the hood at minus 5 degrees F, on a 75 foot extension cord, kept doing its thing. While it's probably not waterproof, it's fairly closed up, so a few drops of water probably won't kill it. It's probably safe to leave this connected continuously as a maintainer on sealed lead-acid (SLA) auto batteries. I've left it connected to a vehicle for a few months with very good results, vehicle always started right up. Note that before starting the vehicle, it's probably best to completely remove this charger from under the hood, otherwise cords could get pulled into belts, burned on hot surfaces, etc. If you do leave it attached to the battery when starting, be sure it's clear of all belts, and I also recommend unplugging it first. That way it won't go into charge mode while the vehicle is starting and running, perhaps giving the electronics in it a longer lifespan. Leaving the charger powered while starting could expose it to voltage and current spikes from inductance, etc. I also put a note on my dash reminding me or anyone else that the charger must be removed before starting and driving away! Seems like a well-made, durable product. The clips are a bit sub-par (cheap plastic, not a great grip on the teeth), but sufficient for the task and amperage. I've used one of them regularly for a couple years now. I would say it's suitable for anything up to a car or small truck, as a maintainer or slow charger. For Gel batteries, I am a little hesitant to use it, because often they have a maximum charging voltage of 14.4 volts. This charger seems to exceed that, briefly at least. Whether that's okay with the relatively low amperage is hard to say, but using too high of a voltage with Gel batteries can cause bubbles to form in the gel, which reduces the performance. I'd check the maximum charging voltage of your Gel battery. DETAILS Below are some detailed observations on charging, for those who want the nitty gritty. I didn't measure the current coming out of this charger, just the voltage while it was connected to SLA automotive batteries. When connected to a battery which is NOT installed in a vehicle (so it has no load on it), the charging circuit turns on and off fairly frequently (every 20-30 mins?) for brief periods. Once the battery drops below about 12.85 V, it will charge at up to about 14.9-15.0 V for a few minutes, then will shut off. When connected to a battery which IS installed in a vehicle (meaning there is always a small load on the battery), the observed charging behavior is somewhat different, and seems to be two-stage. In this case, when the battery drops below the float voltage of about 12.85 V, the charging circuit will come on and the voltage will begin rising gradually. This stage is probably constant-current charging at 2 amps. Once the voltage reaches about 14.85 V (which could take minutes or hours depending on the battery's state of charge), it will stay there for a few minutes, then will drop to constant-voltage charging at about 14.25 V. (Constant voltage charging means the voltage is held steady, which means the current is likely allowed to decrease below 2 amps. It's basically topping it off at this stage.) It will stay at that 14.25 V for maybe 30-90 minutes (depending on any minor loads on the battery), then will shut off. The battery voltage will then slowly decrease. In a healthy battery, it will level off at about 12.90 V. With most vehicles, there is still a small load even when off, so it will continue slowly decreasing. After usually a few hours, the voltage will reach the float voltage of about 12.85 V, and the two-stage charging cycle will begin again. All of this tells me that this is probably a pretty safe maintainer for a vehicle's battery, unlikely to overcharge by very much over time, yet keeping the battery well topped off. SLA batteries like a full charge, it helps their lifespan. So if you're not driving your vehicle every few days, keeping it on this maintainer continuously, or at least turning on the maintainer for a couple hours daily, will likely improve your battery's lifespan and performance. If you'd like to monitor what this or any other charger is doing, and keep an eye on a battery more closely over time, I found the ANCEL BM200 PRO 12V Lead Acid Battery Monitor to be very handy. You can see my review for that as well.

The DeWALT DXAEC2 2-Amp Automotive Battery Charger and Maintainer is an exceptional piece of garage gear. It does an outstanding job keeping my C6 Corvette’s battery completely healthy and ready to roll. If you own a Corvette, you know these cars are notorious for "parasitic draw." The electronics on the C6 can quickly drain a battery if it sits in the garage for more than a couple of weeks. This DeWALT maintainer completely solves that headache. Why It Is Perfect for the C6 Corvette • Flawless Long-Term Maintaining: The fully automatic, micro-processor-controlled charging detects exactly when the Vette's battery needs a top-off. It switches seamlessly from charge mode to float/maintenance mode, preventing overcharging. • Low and Steady Amperage: The 2-amp output is ideal for standard maintenance. It feeds a gentle, steady trickle that protects the battery chemistry and extends its overall lifespan. • Plug-and-Forget Convenience: Hook it up, plug it in, and walk away. The digital display and simple LED indicators give you an instant, clear readout of the battery's voltage and charge status. Key Product Highlights • Heavy-Duty Build: True to the DeWALT name, the housing is rugged, durable, and built to survive busy garage environments. • Versatile Connections: It comes with heavy-duty metal battery clamps for a quick under-hood connection, as well as 12V DC accessory rings for a more permanent, semi-hidden hookup. • Smart Safety Features: The built-in reverse polarity protection guarantees peace of mind. It won't spark or damage your sports car's sensitive electrical systems if you accidentally mix up the terminals. Final Verdict There is nothing worse than walking out to your C6, pushing the start button, and hearing a dead click. The DeWALT DXAEC2 completely eliminates that stress. It is a reliable, tough, and highly efficient smart charger. It keeps the battery optimized during long periods of storage, ensuring the Corvette fires up instantly every single time. It is worth every penny to protect your investment.

Terrible, as if a Chinese knockoff or something. I love Dewalt but don’t think these are legit. 4/5 don’t work, rattling inside. Very fragile. Don’t waste your money.

Perfect for keeping car batteries topped up during winter, I still use lead acid batteries in my cars so this 2 amp charger dose the trick, normally I have a solar panel set-up but cloudy weather prevents charging, case is durable and connections are very good, I have mine in a waterproof power strip case for rainy days as an extra protection.

I bought three of these a little over a year ago. They have all worked fine, until now. One unit just quit working, just outside the warranty period. I plan to buy two more, but of course I will not be buying DeWalt. There is no reason a simple unit like this should not last 20 years or more. I recommend looking for a different brand. UPDATE: AFTER POSTING THIS REVIEW, DEWALT REACHED OUT & STOOD BEHIND THE PRODUCT, EVEN THOUGH THEY WERE OUTSIDE THE WARRANTY PERIOD - MY FAITH IN DEWALT IS RESTORED!
