Battery-powered grease guns for tractors, trucks, mowers and equipment, ranked from live Amazon data.
Ranked by ToolboxTop10 from Amazon data captured Oct 10, 2026. How we rank
A cordless grease gun pumps grease with a motor instead of your hand, which saves hours on farm, fleet and equipment maintenance. We ranked 10 best-sellers on rating, review volume and features (a battery in the box, a hose of 40 inches or more, speed control and a work light).

Already own batteries?
Batteries only fit their own brand's platform, so the best tool for you is often the best
one that runs on the packs you already have. Here's our top-ranked pick on each platform on this page.
A tool-only model skips the cost of a battery and charger you don't need.
Tools sold as "compatible with" another brand's batteries aren't listed here. They're made by third parties, and the battery brand doesn't warrant them.
Where the deals are
The tools ranked here come from DEWALT, Milwaukee, TaskStar, CRAFTSMAN, RYOBI, Seesii, and Alloyman. Prices on these brands move week to
week on Amazon, and the deepest cuts usually land around Prime Day and Black Friday.
Every price button on this page opens the live listing, so you always see today's
number, not the one we captured on 2026-10-10. If your pick is over budget
right now, check back in a few days — DEWALT and Milwaukee rotate through sales and bundle
deals often.

How we rank
Every tool gets one score from 0 to 100, weighted
45% on its star rating,
35% on how many people have reviewed it (more reviews = more
confidence the rating is real), and 20% on the features that
matter for the job. The list is ordered by that score. Best Overall is our pick for the
best all-around, ready-to-use tool; Best Budget the best value at or under
$110; and Money No Object the one to buy if price is no object.
The features score is built from a complete kit (30%), long hose (25%), speed control (25%), an LED work light (20%), capped at 100. The review-count score is on a log scale, so each tenfold jump in reviews adds the same amount, and 7,000 or more reviews gets full marks. Open Why this score on any tool to see its numbers.

Buyer's guide
How much pressure do I need?
Most grease fittings take far less than 10,000 PSI. The high rating matters for clogged or seized fittings, where a manual gun can't push through. Every gun here except the M12 is rated 10,000 PSI or more.
What does flow rate change?
Flow (oz per minute) is how fast grease comes out. Higher flow fills big bearings and equipment faster. DEWALT lists 5 oz/min; RYOBI and CRAFTSMAN claim 7.5 to 9 oz/min.
Bare tool or kit?
If you own batteries from the same brand, buy the bare tool. If you don't, a kit from DEWALT or Milwaukee costs more but leaves you on a platform you can grow into. The no-name kits are cheapest but their batteries fit nothing else.
Cartridge or bulk grease?
All of these take standard 14 oz cartridges. Many can also be filled from a bulk tub, which is cheaper if you grease a lot of equipment.
How long a hose do I need?
Forty inches or more lets you reach fittings under a mower deck or up on a loader arm without moving the gun. The RYOBI's 30-inch hose is the shortest here.
Tools to avoid
Not everything in the search results deserves your money.

CICZ
Electric Grease Gun Compatible with DeWalt 20V Battery (Tool Only)
4.282 reviews$107.63
The listing contradicts itself about what's in the box, so you can't know what you're paying for. The bare DEWALT DCGG571B has more than 70 times the reviews.
Why we'd skip it
The title says '(Tool Only)' and the first bullet says the battery and charger are not included, but the last bullet promises 'Grease gun, 2x 4.0Ah batteries, charger' in a complete kit.
It also says you need a 4.0Ah or larger battery 'to maintain maximum 12,000 PSI pressure', so the headline rating depends on a battery the title says you supply yourself.
It's rated 4.2 stars, the lowest of the grease guns we looked at.
