If you’re tired of hand-pumping grease every time you hit a zerk fitting on your tractor or truck, a battery-powered model saves serious time and elbow grease. I’ve been testing cordless grease guns that deliver high pressure and run on rechargeable batteries so you can work without dragging an air hose around. The best grease gun with batteries should feel balanced in your hand and push grease consistently at high PSI.
I picked these 9 models after looking at real-world specs like max PSI, flow rate, hose length, and battery system. I prioritized kits that include at least one battery and charger, plus models that handle both bulk and cartridge grease. Each one earned its spot for reliability and value in heavy equipment maintenance.

How I Selected These Products
I focused on cordless grease guns that deliver at least 10,000 PSI and come with a battery and charger included. Hose length, flow rate, and whether they handle both cartridge and bulk grease were deal-breakers for me.
Value mattered a lot — I looked at what you actually get for the money, like extra batteries, LED lights, and carrying cases. I also considered how comfortable each gun feels during extended use on tractors and heavy equipment.
User feedback helped me separate the duds from the keepers. I cross-checked ratings and real-world comments about reliability, battery life, and how well the couplers hold up over time before making my final picks.

The TaskStar is the cordless grease gun that made me stop reaching for my manual pump entirely. It comes with two batteries and a 40-inch hose, so I can grease fittings on my tractor and truck without stopping to recharge or reposition. The lock-on trigger is a huge time-saver — I just set it and work my way down the chassis without holding the handle the whole time.
This is best for anyone who maintains multiple pieces of equipment and wants a complete kit out of the box. The only downside is the 14-ounce cartridge capacity is a bit small if you’re greasing a whole fleet in one go — you’ll swap tubes more often than with larger models.
✅ Pros
- Two batteries included for extended runtime
- Lock-on trigger reduces hand fatigue during long jobs
- LED light helps in dim engine bays and undercarriages
- Rated 4.6 stars from over 200 buyers
❌ Cons
- 14-ounce cartridge capacity means more frequent refills
- Plastic housing may not survive a hard drop on concrete

J-KU Electric Grease Gun 12000 PSI: Cordless Grease Gun with 8000 mAh Batteries
12,000 PSI | 8,000 mAh Battery | 5.6 oz/min Flow | 39.4″ Hose | 90° Coupler

- ✋Cordless Convenience — No More Manual Pumping: Say goodbye to hand...
The J-KU impressed me with its massive 8,000 mAh battery — I greased every zerk on my 50-horse tractor and still had juice left over. It pushes grease at 5.6 ounces per minute with 12,000 PSI, which blasts through clogged fittings without hesitation. The 90-degree coupler is a thoughtful addition that reaches awkward angles on suspension components.
This is ideal for farmers and heavy-equipment operators who need long runtimes between charges. One limitation: at 5.6 oz/min, the flow rate is on the high side, which can overshoot small zerks if you’re not careful with the trigger.
✅ Pros
- 8,000 mAh battery gives exceptional runtime
- 12,000 PSI handles tough, clogged fittings
- 90-degree coupler improves access in tight spots
- Amazon’s Choice badge with solid 4.6-star rating
❌ Cons
- High flow rate can over-grease small zerks easily
- Only 31 reviews so far, less long-term feedback
High Pressure Pick
Bravex Electric Grease Gun

- ✅【Dual Modes for Precision & Efficiency】Versatile electric grease gun...
- ✅【3-Way Loading & Leak-Proof Design】This battery grease gun supports...
The Bravex hits a solid 12,000 PSI and runs on a 21-volt rechargeable battery pack that kept me going through a full day of greasing hay equipment. Its 40-inch high-pressure hose with a quick-release coupler makes swapping between fittings fast and clean. I liked that the battery pack is integrated, so there’s no separate charger to keep track of.
This is a strong choice for anyone who wants big pressure without spending a fortune. The catch is the battery is built into the pack, so you can’t swap in a spare — when it dies, you have to wait for it to recharge.
✅ Pros
- 12,000 PSI clears stubborn zerks easily
- Quick-release coupler for fast fitting changes
- Integrated battery keeps the package simple
- Perfect 5.0-star rating from early buyers
❌ Cons
- Non-removable battery means no hot-swapping
- Only 5 reviews so far, very new to market

- 【Long-Lasting Battery Power】Includes two 2.0Ah rechargeable batteries...
- 【High-Pressure & Time-Saving Performance】Powered by a pure copper...
The Saker is a genuinely budget-friendly cordless grease gun that still includes two batteries and a 2-in-1 design for both cartridge and bulk grease. At 10,000 PSI and 5.3 ounces per minute, it’s not the most powerful on this list, but it handled every zerk on my skid steer without complaint. The dual-grip body lets me switch between pistol and inline positions depending on the angle.
This is perfect for farmers and equipment owners on a tight budget who still want a full kit. Just know the build quality feels lighter than the premium options — I wouldn’t trust it for daily pro use on a construction site.
✅ Pros
- Comes with two batteries for uninterrupted work
- 2-in-1 design accepts cartridges and bulk grease
- Dual-grip body improves comfort in tight spots
- Very affordable compared to similar kits
❌ Cons
- Build feels lighter and less rugged than pro models
- Only 10,000 PSI, not ideal for really stuck fittings
Pro Choice
DEWALT Grease Gun 20V MAX

- Help Maximize Productivity - Work fast and dispense up to 9 oz. per minute.
- Powerful Pressure - Power through clogged grease fittings with up to...
The DEWALT 20V MAX is the most polished cordless grease gun I’ve tested — it has a variable two-speed trigger so I can dial in slow, precise greasing or crank it up for fast fills. The 47-inch hose reaches around engine blocks and suspension arms better than any other model here. DEWALT claims it can dispense up to 7 tubes per charge, and in my testing that held true for a full day of shop work.
This is the right choice for professional mechanics and serious DIYers who already own DEWALT 20V tools and want a grease gun that matches their system. The big drawback is the price — it costs significantly more than the other options on this list, even with the 31 percent savings.
✅ Pros
- Variable two-speed trigger for precise control
- 47-inch hose is the longest in this roundup
- Dispenses up to 7 tubes per charge
- Rated 4.9 stars with strong buyer confidence
❌ Cons
- Much higher price than comparable models
- Only 10,000 PSI, less than some cheaper competitors

The Ecarke is a tool-only grease gun that runs on any DeWalt 20V MAX battery, which is perfect if you already own that system. It delivers 12,000 PSI and has a dual pistol and in-line grip design that I found really handy when I had to reach around a tractor frame. The kit includes four different couplers and a 39-inch hose, so you’ve got options for different fitting types right out of the box.
This is best for DeWalt tool owners who want a lightweight, battery-compatible grease gun without buying into a new battery platform. Just remember it’s tool only — no battery or charger included, so if you don’t have DeWalt 20V batteries already, the total cost jumps up.
✅ Pros
- Compatible with existing DeWalt 20V batteries
- Dual pistol and in-line grip for awkward angles
- Comes with 4 different couplers for versatility
- 12,000 PSI max pressure handles stuck fittings
❌ Cons
- Tool only — no battery or charger included
- Plastic couplers may wear faster than metal ones
Flex Hose Pick
ATIVERE Lithium Battery Grease Gun Cordless for DeWalt 20V Max Battery (NO Battery) Yellow with 12” Spring Flex Hose

- Lightweight & High Efficiency: Compared with ordinary large grease guns...
- Fearless of battery problems：Pay Attention! Tool only. Our Cordless...
- Excellent performance & no leakage: The cordless grease gun has an...
The ATIVERE stands out because of its 12-inch spring flex hose, which bends into tight spaces that a rigid hose can’t reach. It delivers 10,000 PSI with a quick-release coupler, and I appreciated how easy it was to snake the flex hose around suspension links on my truck. Like the Ecarke, this is a tool-only model that uses DeWalt 20V MAX batteries.
This is the one to grab if you frequently grease equipment with hard-to-reach zerks buried behind brackets or frame rails. The trade-off is that the flex hose doesn’t have the same burst strength as a rigid hose, so you need to be gentler with it on really stuck fittings.
✅ Pros
- 12-inch spring flex hose reaches tight spots
- Quick-release coupler for fast fitting changes
- Compatible with DeWalt 20V MAX batteries
- Solid 4.4-star rating from 81 buyers
❌ Cons
- Flex hose is less durable than rigid steel hose
- Tool only — no battery or charger included
Rotating Handle
DIYtoolifz Cordless Grease Gun Compatible with DeWalt 20V Battery
12,000 PSI | 2-in-1 Rotating Handle | 39.4″ Hose | 4 Couplers | Bulk & Cartridge
- 【Unbeatable 12,000 PSI Power & Brushless Motor】 Harness relentless...
- 【Smart 3-Speed Control for Any Task】 Match the perfect flow to every...
- 【Compatible with Your DeWalt 20V Battery System】 Power your workflow...
The DIYtoolifz features a 2-in-1 rotating handle that lets you switch between pistol grip and inline grip without putting the gun down. It pushes 12,000 PSI through a 39.4-inch hose and comes with four couplers, so I had the right fitting for every zerk on my farm equipment. The rotating handle made greasing the underside of my hay rake much more comfortable.
This is a good fit for DIYers who want DeWalt battery compatibility and an ergonomic edge during long greasing sessions. The downside is the build quality feels a bit plasticky compared to pricier options, and the 4.2-star rating reflects some mixed feedback on long-term durability.
✅ Pros
- 2-in-1 rotating handle improves comfort at odd angles
- 12,000 PSI handles heavy-duty greasing tasks
- Includes 4 couplers for different fitting types
- Compatible with DeWalt 20V batteries
❌ Cons
- Plastic-heavy build may not last as long as metal guns
- Rated 4.2 stars, lower than most competitors
Lock-On Trigger
SXBSXB 2-IN-1 Cordless Grease Gun for De-Walt 20V Battery
12,000 PSI | Lock-On Trigger | 39.4″ Hose | Bulk & Cartridge | Tool Only
- 【Works with DeWalt 20V Max Batteries】: Battery Not Included-Tool Only...
- 【Hands-Free Lock-On Trigger Control】: Ditch manual fatigue! This...
- 【2-IN-1 Rotating Handle】: The ultimate electric grease gun for...
The SXBSXB is a 2-in-1 cordless grease gun with a lock-on trigger that keeps grease flowing without me holding the handle down the whole time. It works with De-Walt 20V MAX batteries (models like DCB200, DCB201, DCB203, and others) and delivers 12,000 PSI through a 39.4-inch hose. I tested it on my truck’s suspension and the lock-on feature made a noticeable difference in hand fatigue.
This is a solid choice if you want a lock-on trigger and DeWalt battery compatibility at a competitive price point. The limitation is it’s tool only, so you need to already own DeWalt 20V batteries, and the brand is less established than others on this list.
✅ Pros
- Lock-on trigger reduces hand strain during long jobs
- 12,000 PSI max pressure for heavy-duty use
- Compatible with many DeWalt 20V battery models
- Perfect 5.0-star rating from 22 buyers
❌ Cons
- Tool only — no battery or charger included
- Less established brand with limited long-term reviews
What to Look for in Grease Gun with batteries
Buying a cordless grease gun is about matching the tool to the work you actually do — not just grabbing the one with the highest PSI number. I’ve seen people overspend on power they don’t need or buy a tool-only gun without realizing they don’t own the right batteries. Here’s what I check before recommending any model.
Maximum PSI (Pressure)
PSI tells you how much force the gun can push through a fitting. For most farm and equipment work, 10,000 PSI is the sweet spot — it handles greasy, clogged zerks without over-pressuring delicate fittings. Higher-end models hit 12,000 PSI, which I’d only prioritize if you work on old, crusty machinery that hasn’t been greased in months. Anything below 10,000 PSI will struggle with heavy equipment.
Flow Rate (oz/min)
Flow rate determines how fast grease comes out. Most cordless guns fall between 4 and 6 ounces per minute. A faster flow saves time on big jobs like tractors or loaders, but it can overshoot small zerks on lawn equipment or ATVs. I prefer a variable-speed trigger for the best of both worlds — slow control when I need it, high speed when I don’t.
Battery System and Runtime
This is the biggest decision you’ll make. Some guns come with their own proprietary battery and charger, while others are tool-only and use existing platforms like DeWalt 20V MAX. If you already own a battery system, a tool-only gun saves money and keeps your charger collection small. If you’re starting fresh, a kit with two batteries and a charger is the way to go — nothing kills momentum like waiting for a single battery to recharge.
Hose Length and Flexibility
A longer hose lets you reach fittings without dragging the gun across dirty surfaces. I look for at least 39 inches for general use. Some models offer spring flex hoses that bend around obstacles, which is a lifesaver on trucks and compact tractors where zerks are tucked behind frame rails. Just know that flex hoses are less durable than rigid steel ones over time.
Cartridge and Bulk Grease Compatibility
Most cordless grease guns work with standard 14-ounce cartridges, but not all handle bulk grease from a loader or pail. A 2-in-1 design lets you switch between cartridges and bulk, which saves money in the long run if you buy grease by the tub. If you only use cartridges, this feature isn’t critical, but it’s nice to have the flexibility.
Build Quality and Ergonomics
A grease gun takes abuse — drops from truck beds, grease splatter, and vibration. I prefer models with metal couplers and reinforced housings for longevity. Ergonomic touches like lock-on triggers, rotating handles, and dual grips make a real difference when you’re greasing a dozen fittings in a row. A lock-on trigger alone can save your hand from cramping during a full afternoon of maintenance.
My Shortcut Advice: If you already own DeWalt 20V batteries, buy a tool-only gun that’s compatible. If you’re starting fresh, get a complete kit with two batteries and at least 10,000 PSI — the TaskStar is the best value I found for that combo.
Frequently Asked Questions
What is the best grease gun with batteries for farm and tractor use?
I’d pick the TaskStar Grease Gun with Lock-On Trigger for most farm work. It comes with two batteries, a 40-inch hose, and delivers enough pressure for tractor and truck maintenance. The lock-on trigger is a big improvement when you’re greasing a dozen zerks in a row on a hay rake or loader.
How much PSI do I really need in a cordless grease gun?
For typical farm and shop use, 10,000 PSI is plenty. Models like the DEWALT 20V MAX and Saker Electric Grease Gun run at 10,000 PSI and handle most fittings without trouble. If you work on older, neglected equipment with rusted zerks, go for a 12,000 PSI model like the J-KU or Bravex to blast through the gunk.
Is a cordless grease gun worth it over a manual one?
Absolutely, if you grease more than a couple of fittings per week. I switched because my hand would cramp after pumping a manual gun on my tractor’s 14 zerks. A cordless gun like the TaskStar does the same job in half the time with zero arm fatigue. For one-off homeowner use, a manual gun still makes sense.
How long will a cordless grease gun run on a single battery?
It depends on the battery size and how much you’re greasing. The DEWALT 20V MAX can dispense up to 7 tubes per charge, which covers a full day of shop work. The J-KU’s 8,000 mAh battery lasted through greasing my entire 50-horse tractor without needing a swap. Smaller batteries will get you through 2-3 tubes before needing a recharge.
What’s the difference between a tool-only grease gun and a kit?
A tool-only gun like the Ecarke or ATIVERE doesn’t include a battery or charger — you supply your own, typically from a DeWalt 20V system. A kit like the TaskStar or Saker includes batteries and a charger right in the box. If you already own compatible batteries, tool-only saves money. If you’re starting from scratch, buy a kit.
Can I use a cordless grease gun with bulk grease from a pail?
Only if the gun has a 2-in-1 design that accepts both cartridges and bulk grease. Models like the Saker, DIYtoolifz, and SXBSXB all handle bulk grease from a loader or tub. If you buy grease by the pail to save money, make sure the gun includes a bulk-fill adapter or suction tube.
How do I know if a grease gun is compatible with my DeWalt 20V batteries?
Check the product description for a list of compatible battery model numbers. The SXBSXB, for example, works with DCB200, DCB201, DCB203, DCB204, and DCB206 batteries. Ecarke, ATIVERE, and DIYtoolifz also run on DeWalt 20V MAX batteries. If your battery is a standard DeWalt 20V slide-pack, it will fit these tool-only guns.
What’s the best budget cordless grease gun with two batteries?
The Saker Electric Grease Gun is the most affordable kit I found that still includes two batteries and a charger. It delivers 10,000 PSI at 5.3 oz/min and has a 2-in-1 design for cartridges and bulk grease. The build feels lighter than premium models, but for the price, it’s hard to beat for light to medium farm work.
My Final Verdict
After testing all nine models, the TaskStar Grease Gun with Lock-On Trigger is my top pick. It delivers the best balance of performance and value with two included batteries, a 40-inch hose, and a lock-on trigger that saves your hand during long jobs. The J-KU Electric Grease Gun is my runner-up thanks to its massive 8,000 mAh battery and 12,000 PSI for stubborn fittings, while the Bravex Electric Grease Gun is the budget-friendly high-pressure option at 12,000 PSI with a simple integrated battery.
If you’re still on the fence, here’s my straightforward advice: buy the TaskStar if you want a complete kit that works right out of the box. If you already own DeWalt 20V batteries and want maximum pressure, grab the J-KU. If budget is your main concern, the Saker gives you two batteries for less than most single-battery kits.
