Read the full review
Milwaukee lists the 2646-20 as an M18 2-speed bare tool with 10,000 PSI max operating pressure, a 48 in flexible hose, an air bleeder valve and a lock-on/lock-off trigger. A pre-set grease counter dial meters the output. The listing states a 5 year tool warranty and a 9 lb weight. As a bare tool it ships without a battery, so it suits someone already on the M18 platform.

- Pre-set grease counter dial
- Lock-on/lock-off trigger
- 5 year tool warranty

Who it's for: an M18 owner who wants the kit with spare batteries.

Read the full review
Milwaukee lists the 2646-22CT as an M18 2-speed grease gun kit with 2 compact batteries, an 18V platform and a 5 year tool warranty. The bullet list is thin, calling it easy to use and highly durable without stating pressure, flow or hose length. One contradiction: the spec table says 1 lithium-ion battery is required while the title describes a kit with 2 compact batteries; we trust the title. The spec table also lists the included components as 'Hand Caulking Guns', which does not describe a grease gun kit.
Pros
- 2 compact batteries in the kit
- M18 platform with 5 year warranty
- 2-speed operation stated
- 16.02 lb listed weight
Cons
- Spec table says 1 battery while the title says 2
- No pressure, flow or hose length stated
- Thin bullet list
- Spec table lists 'Hand Caulking Guns' as included components

Buying guide: choosing the best battery powered grease gun
Pressure and flow
Four of the five listings state a 10,000 PSI max pressure; the Milwaukee 2646-22CT kit does not state a pressure figure. That pressure is what pushes grease through clogged or dirty fittings. Flow is stated on two: the DEWALT at 5.0 oz/min and the RYOBI at 7.5 oz/min, the highest here. Higher flow fills a fitting faster; pressure breaks through a stuck one.
Hose length
Hose length decides which fittings you can reach without moving the tool. The Milwaukee 2646-20 states 48 in, the longest here, followed by the DEWALT at 42 in, the Lincoln at 36 in and the RYOBI at 30 in. The Milwaukee 2646-22CT kit does not state a hose length. For zerks buried behind mower decks and tractor frames, longer is better.
Kit, bare tool or tool-only
The Lincoln ships the full kit: 2 batteries, a charger and a case. The DEWALT ships a 4.0 Ah battery and charger. The Milwaukee 2646-22CT ships 2 compact batteries. The Milwaukee 2646-20 is a bare tool and the RYOBI P3410 is tool-only, so both need a battery you already own. Match the gun to the battery platform on your shelf: M18, 20V MAX, RYOBI 18V or Lincoln 20V. Our best grease gun for home use covers the manual side of the family.
Counter dial, LED and bleeder valve
The small extras separate the picks. The Milwaukee 2646-20 has a pre-set grease counter dial that meters output. The DEWALT, Lincoln and RYOBI state an LED light for dark fittings. The DEWALT and Milwaukee 2646-20 state an air-bleeder valve for priming after a cartridge change, the Lincoln a vent valve for the same job, and the DEWALT adds a pump filter screen against dirt.
Warranty
The two Milwaukee listings and the Lincoln state a 5 year tool warranty, with the Lincoln adding a 2 year battery warranty. The DEWALT states a 3 year limited warranty. The RYOBI states no warranty term. A grease gun lives a hard life in a dusty shop, so a stated term is worth weighing.
Read the manual, keep children and pets out of the yard while you work, wear eye and hearing protection and sturdy footwear, and never exceed the slope rating of your machine. Refuel only with the engine off and cool. See CPSC lawn mower safety. Read our Safety Disclaimer.
Matching It to Your Property
- Battery platform comes first: the gun should share batteries with your other tools, whether M18, 20V MAX, RYOBI 18V or Lincoln 20V.
- For hard-to-reach fittings on mowers and tractors, the 48 in Milwaukee hose reaches farthest; the 30 in RYOBI suits compact machines.
- Weight matters for overhead zerks: 8.3 lb for the RYOBI against 14.8 lb for the DEWALT.
- Storage is simple: the Lincoln’s case keeps the kit together in the shop, while the bare tools ride in the toolbox.
The Acre Score explained
The Acre Score weighs five factors: performance (pressure, flow, hose and battery), build quality (tube, hose and fittings), value (specs for the money), safety and warranty (years and coverage). A factor the listing does not state scores zero. The weights are on our How We Pick page.
| Product | Acre Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Lincoln 1884 PowerLuber | 9.6 | 33 | 22 | 21 | 0 | 4 |
| DEWALT DCGG571M1 | 9.6 | 32 | 21 | 20 | 0 | 3 |
| Milwaukee 2646-20 | 9.5 | 30 | 20 | 18 | 0 | 4 |
| Milwaukee 2646-22CT | 9.5 | 28 | 19 | 20 | 0 | 4 |
| RYOBI P3410 | 9.5 | 32 | 20 | 20 | 0 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
FAQ: mowing large lots
When should I use a grease gun?
When a fitting is due for fresh grease: mower deck spindles, tractor joints, trailer bearings and any zerk the manual calls out. A battery gun makes the job quick enough that it actually gets done.
How do you work a battery grease gun?
Push the coupler onto the fitting until it seats, then pull the trigger and watch for fresh grease at the joint. After a cartridge change, use the air-bleeder valve to prime the pump, as the DEWALT and Milwaukee listings describe.
How do you clean a grease gun?
Wipe the coupler and body clean after each use so grit never reaches the fitting. The DEWALT’s pump filter screen is there to catch dirt before it reaches the pump mechanism.
Can you leave grease in a grease gun?
Yes. A grease gun is stored with grease in it between jobs; that is how the listings describe them. Keep the coupler clean and the tool out of the weather.
