Introduction
If you've been following along with our Hilti Nuron coverage, you know the battery platform is a big deal. One battery family that works across the entire tool lineup is already a game changer, but a battery is only as good as how fast you can get it charged and back into a tool. That's where the charger lineup comes in, and Hilti has put a lot of thought into giving you options depending on how hard you're running your tools. I want to be upfront that this is a sponsored article with Hilti, a brand I've trusted for a long time, so you know where I'm coming from. Trust me, if I didn't believe it, I wouldn't talk about it. But I have studied batteries for a long time, and once you break them down, you can easily see why the Nuron is the best battery platform on the market. Today we're looking at the full charger and battery lineup, but the star of the show is the new C 8D-22 dual bay flash charger.
The Nuron Charger and Battery Lineup
Hilti offers four chargers in the Nuron lineup, the C 4-22, the C 6-22, the C 8-22, and the new C 8D-22. Each one steps up in terms of charging speed and output, so depending on how many tools you're running and how hard you're pushing them, there's a charger that fits your situation. On the battery side you have five options, the B 22-55, B 22-85, B 22-195, B 22-260, and the B 22-290. The numbers roughly correspond to the watt-hour capacity, so the bigger the number the more runtime you're getting. The B 22-55 is your compact lightweight option and the B 22-290 is the big dog you throw on your heaviest tools when you need all day runtime. All of them work across every Nuron tool, which is the whole point of the platform.

Meet the C 8D-22
The C 8D-22 is Hilti's fastest dual bay charger and it's the one I'm most excited to talk about. It puts out 900 watts and 36 amps, which is a lot of charging power. What makes it different from just having two single chargers sitting next to each other is that it charges both bays in parallel, meaning each battery gets the same fast charge it would get from a single C 8-22 charger. You're not splitting the power between two batteries and waiting twice as long. Both slots are running at full speed at the same time. It also has three built-in cooling fans that are designed to bring batteries back down to a chargeable temperature faster after heavy use. If you've ever pulled a hot battery off a tool and had to wait for it to cool down before the charger would take it, that's exactly the problem these fans are solving. The status display on the front shows you what's going on with each battery so you're never guessing.
Flash Charging and Why It Matters
The C 8D-22 is optimized for Hilti's flash charging batteries, the B 22-260 and B 22-290. When you pair one of those batteries with a flash charger, it can reduce the cooldown and charging time to 80% capacity by up to 70% compared to a standard charge cycle. In real world terms, that means less time waiting and more time working. If you're running heavy tools all day, that kind of turnaround on your batteries changes how you manage your workflow. Instead of needing a big stack of batteries to rotate through, you can work with fewer batteries because they're coming back so much faster.

Mount It, Set It, Forget It
One thing I really like about the C 8D-22 is that Hilti built in through-holes so you can screw it directly to a wall or a shelf in your shop or on your rig. It also has an exchangeable power cord, so if the cord ever gets damaged you're not replacing the whole charger. For something that's going to live in one spot and run constantly, those two details matter a lot. Set it up once, plug it in, and it's just there ready to go whenever you need it.
FAQ
It charges that battery at full speed just like a single bay C 8-22 would. You're not losing anything by only using one slot at a time.
No, it works with all Nuron batteries. The flash charging feature is just an extra benefit you get when you pair it with the B 22-260 or B 22-290. With standard Nuron batteries you're still getting the fastest dual bay charging Hilti offers, just without the flash charging bump.
The C 8D-22 is designed for the Nuron platform, so if you have older Hilti batteries from a previous platform they won't work with it. If you're making the switch to Nuron though, it's a good time to evaluate what batteries you actually need and build from there.
Final Thoughts
The C 8D-22 is the kind of charger you buy when you're serious about how you run your tools. Two bays running at full speed simultaneously, flash charging compatibility, built-in cooling fans, wall mountable, exchangeable power cord. Hilti thought through every detail on this one. And when you pair it with the right batteries, the turnaround time is genuinely impressive. If you're building out a Nuron setup or already running one and still using a slower charger, this is worth the upgrade.
