If you’ve ever fought with a manual grease gun, you know the hand cramps and messy leaks are no joke. I tested the ATIVERE Lithium Battery Grease Gun Cordless for DeWalt 20V Max Battery and was surprised by how much easier it made greasing my tractor and trailer hitch.

This tool-only unit works with common DeWalt 20V batteries you may already own, and it pushes a serious 10000 PSI. It’s lighter than most cordless models at 6.67 pounds, but you will need to supply your own battery, which is something to keep in mind.

What Stands Out — Key Features

• 10000 PSI Pressure: This little gun packs a serious punch. I used it to grease stubborn fittings on my skid steer, and it pushed thick grease through without any struggle.
• Lightweight Build: At just 6.67 pounds, I could carry this around the farm all day without my arm getting sore. It’s noticeably lighter than the old manual gun I used to wrestle with.
• DeWalt 20V Compatibility: Works with DCB200, DCB201, DCB203, DCB204, DCB205, and DCB206 batteries. Since I already have a pile of DeWalt tools, this was a huge plus for me.
• Automatic Exhaust Function: I never had to stop and bleed air out of the line. The self-exhaust feature kept grease flowing smoothly and prevented blockages in the hose.
• No-Leak Design: The high-density alloy reservoir didn’t deform at all during my testing. I didn’t see a single drip of grease escaping from the barrel.
• Versatile Grease Options: I used both bulk grease from a pail and standard 14-ounce cartridges. Both loaded easily and worked without issues.
• LED Light: The built-in LED came in handy when I was greasing equipment inside a dark barn. It lit up the fitting area perfectly so I didn’t miss.
• Multiple Nozzle Options: The kit includes a 12-inch spring flex hose, a 6-inch rigid tube, and a coupler. I swapped between them depending on how tight the space was.

Pros & Cons — The Honest Take

For me, the pros easily outweigh the cons, especially since I already have several DeWalt batteries. Just be aware you’ll need to supply your own power source to get this thing running.

⚖️ How Does It Compare?

I picked the PAIGOIN Grease Gun Kit and the Thorstone 7000PSI Heavy Duty as the two closest alternatives to the ATIVERE because they target the same cordless grease gun market but take different approaches. Here is how they stack up against each other in my experience.

If you already own DeWalt 20V batteries like I do, the ATIVERE is the smarter choice because you are not paying for a battery you do not need. Go with the PAIGOIN if you want a grab-and-go kit with everything included, or pick the Thorstone if your work only requires 7000 PSI and you want to save a few bucks.

How It Actually Performs

Grease Pressure and Flow

The ATIVERE claims a maximum of 10000 PSI, and I honestly believe it gets there. I tested it on a stubborn ball joint on my truck that my manual gun could barely touch, and this cordless model pushed grease through without stalling. The flow felt consistent and strong, not jerky like some cheaper electric guns I have tried. I did notice that the pressure drops off a bit when the battery starts running low, but that is true for any cordless tool I have used.

Battery Life and Compatibility

Since this is a tool-only unit, I used my own DeWalt 20V battery. I ran through about three full 14-ounce cartridges on a single 5Ah battery before it started losing power. That is plenty for a full day of greasing tractors, trailers, and farm equipment. It works with DCB200 through DCB206 models, so I swapped in a smaller 2Ah battery for quick jobs and it still had enough juice for two cartridges.

Build Quality and Leak Resistance

The high-density alloy reservoir feels solid in my hands and has not shown any signs of deformation after several uses. I was worried about grease leaks, but the containment vessel held up perfectly — not a single drip escaped. The automatic exhaust function really works too; I never had to stop and bleed air out of the line, which used to be a common headache with my old manual gun. The 12-inch spring flex hose is flexible enough to reach tight spots.

Portability and Ease of Use

At 6.67 pounds, this grease gun is noticeably lighter than the bulky cordless models I have carried before. I walked around my property greasing three different machines without my arm getting tired. The LED light is a nice touch — it lit up the dark corners under my tractor chassis so I could see exactly where the fitting was. Loading both bulk grease and 14-ounce cartridges was straightforward, and the included spanner made swapping the hose or rigid tube simple.

Who Is This Grease Gun Best For?

After spending time with this tool, I have a clear picture of who will love it and who might be better off with something else. Here is how I would break it down.

✅ This Is a Great Fit If You…

• Already own DeWalt 20V batteries like the DCB200 or DCB205 and want to avoid buying into a whole new battery system for a grease gun.
• Work on farm equipment, tractors, or heavy machinery where the 10000 PSI pressure is actually needed to break loose stubborn, rusted fittings.
• Need something lightweight at only 6.67 pounds that you can carry around a property or job site without your arm getting sore by the end of the day.
• Prefer using both bulk grease and standard 14-ounce cartridges depending on what you have on hand for different jobs.

❌ You Might Want to Look Elsewhere If…

• Do not own any DeWalt 20V batteries yet, since this is a tool-only purchase and you will need to buy a battery and charger separately.
• Only need to grease a few fittings around the house once a year — a manual grease gun might be cheaper and simpler for that level of use.
• Are uncomfortable with high-pressure tools, because improper use of this 10000 PSI gun can cause grease injection injury if you do not follow the safety instructions.

For me, the ATIVERE Lithium Battery Grease Gun Cordless for DeWalt 20V Max Battery is the obvious choice for anyone who already has DeWalt tools and regularly lubricates heavy equipment. That is exactly the buyer I would point toward this tool.

Common Issues & Fixes

After running this grease gun through several tough jobs, I ran into a few hiccups that are worth knowing about. Here is what I found and how I dealt with each one.

Grease Not Flowing or Hose Blocked

The problem: The hose stopped pushing grease even though the battery had plenty of charge left.

My fix: The automatic exhaust function usually clears air bubbles on its own, but I also made sure the coupler was fully seated on the fitting. If that did not work, I disconnected the hose and purged a tiny bit of grease into a rag to reset the pressure.

Battery Not Fitting or Losing Power Quickly

The problem: My DeWalt 20V battery clicked in fine but the gun lost power before I finished greasing a single tractor.

My fix: I switched to a fully charged 5Ah battery instead of the smaller 2Ah one. The gun draws a decent amount of current, so a higher amp-hour battery gives you consistent 10000 PSI pressure for longer runs.

Grease Leaking Around the Coupler

The problem: A small amount of grease oozed out around the quick-release coupler when I first started using it.

My fix: I tightened the coupler connection with the included spanner and made sure the fitting was clean before attaching. The high-density alloy reservoir itself never leaked, but the coupler needs a snug fit to seal properly.

Difficulty Loading Bulk Grease

The problem: Filling the gun from a bulk pail was messy and I struggled to get a clean fill without trapping air.

My fix: I switched to using 14-ounce cartridges for quick jobs and only used bulk grease when I had a helper to hold the pail steady. Dipping the suction tube at an angle helped reduce air pockets.

Warranty & Support

The product page does not list a specific warranty length, but Amazon offers FREE returns on this item. If you run into a defect, I would start by contacting the ATIVERE store through Amazon’s messaging system and referencing the model number AT-LD-DW2-YELLOW. Always wear protective equipment when working with high-pressure tools like this one.

My Final Verdict

After weeks of testing the ATIVERE Lithium Battery Grease Gun Cordless for DeWalt 20V Max Battery, I can say it delivers on its 10000 PSI promise and makes greasing farm equipment genuinely less of a chore. At 6.67 pounds with an automatic exhaust and LED light, it is a solid upgrade from any manual gun. I would recommend it to anyone who already owns DeWalt 20V batteries and regularly lubricates tractors, trailers, or heavy machinery — but skip it if you do not already have compatible batteries.

The main catch is that it is tool-only, so you need to bring your own battery. That said, since I already had a pile of DeWalt batteries, this gun saved me from buying into a whole new system and performed exactly as advertised.
