Do you own a truck, a tractor, or a heavy machine that has plenty of mechanical parts? If yes, then lubricating the moving parts inside must have been a hell of a task!
Of course, you can’t expect the machine to run efficiently without lubricating the parts regularly.
However, if proper grease coupled with a perfect grease gun is not used, just wait for the machine to lose its life in no time. A battery-powered grease gun can be the sorcerous stone that keeps your machine as functioning as a new one!
Finding the best battery powered grease gun doesn’t need to be a hard nut to crack. We have got you covered! Read this post to find out the top 5 best grease guns that run on batteries.
Before You Buy, What to Look For?
Before you proceed, let’s see what you need to consider before buying the best battery operated grease gun. Keep these facts in mind to get the best deal possible.
Ideal Pressure and Flow Rate
For any grease gun, the more the pressure the machine delivers, the better the lubrication. Plus, make sure the gun can produce a great flow of grease, at least at a 5 oz per minute rate.
Take the 20V Max Grease Gun from Dewalt, for example. It can produce a 10000 PSI of pressure and 5 oz/minute grease flow – a perfect combination.
Longer Battery Life
A battery-powered grease-gun is all about battery life. If your gun runs out of battery after a few ounces of greasing, this machine isn’t any good for you. Look for the grease guns that include batteries that last at least 5 to 10 cartridges of grease. That’s enough for a whole day of work.
Long Hose for Better Reach
The gun hose can play a key role in reaching some hard-to-reach parts of the machine you are lubricating. A 40-inch or longer hose grants the gun a better option to lubricate even the tiniest parts of the machine.
Best Battery Operated Grease Gun Reviews
If you want to get your hands on the best one, check the reviews I’ve mentioned below. I’ve talked about the top 5 grease guns available in the market.
1. DEWALT 20V Max Battery Grease Gun
The 20V Max Grease Gun from Dewalt is a heavy performer in true sense. Boasting one of the most powerful motors, this machine is capable of producing a maximum of 10000 PSI.
Besides the incredible amount of pressure it produces, the grease gun shoots the grease at a flow of 5 oz per minute. That’s enough of a flow to lubricate all the insides of a machine.
Depending on the heavy-duty batteries, you can easily leave your greasing tasks up to the impressive 16 cartridges with a single charge.
It’s so annoying if you can’t push the grease gun a bit further than where you are because of the shorter hose. Well, that’s not going to be the case with this perfect gun. You can extend the hose up to 42 inches to reach the places you find a hard time reaching.
It has a built-in LED light attached to it for better vision in low light. It’s definitely tough to see what you are greasing in darker places inside the machine. The LED light is an awesome addition, we must say!

With a superb flow-rate of 10 oz per minute, the 2646-22CT M18 from Milwaukee stands as a strong contender to all its peers.
It can produce an impressive amount of 10000 Pound-force per square inch, which allows the grease to make its way through the necessary parts of your machine. When you have 10000 PSI of pressure with 10 oz of flow per minute, lubricating should be the easiest task of your life.
Having a 48-inch long flexible hose does add some advantage of better maneuverability and extension. You can take your gun-head to the furthest of places inside your machine to lubricate the required parts.
Although the battery-power could have been a bit more impressive, still the machine can last around 10 cartridges with a single charge. That’s enough to lubricate any heavy machinery on one go.
If you need to lubricate a sensitive part of your machine with utmost precision, just set the rate on the built-in grease-counter. That’s very helpful if you are a professional.

Like its peer model, the 2646-22CT M18, this one is equally capable of producing the industry-leading max operating-pressure of 10000 PSI. Using the 2-speed options, you can set the maximum and minimum flow and pressure the gun delivers.
It has a plunger rod that comes with markings. So, you’ll know how much grease you’ve still got inside the barrel and how much you’ve used up. This helps you to refill at the right time before you run out of grease in the middle of a hectic lubricating work.
Carry the gun very easily on your shoulder with the shoulder strap. You will get better control and less fatigue on your hands and shoulders.
The 18V battery can provide a day-long lubrication work if you are not planning to use it at a stretch. Take note that this is the only 18V battery gun that you will find!

How to Use a Battery Powered Grease Gun?
A battery-powered grease gun is a cordless version of a normal electric grease gun. You don’t need to put extra effort into using it. Here are a few steps to take full advantage of a battery-powered grease gun.
First, you need to load the cartridge with grease. Make sure the grease level indicator on your grease gun marks the grease level as full.
Next, check if the battery is charged enough. You will not want to be disturbed by the sudden battery run-out.
Now, take the grease hose pipe to the exact part of the machine where you need to lubricate. If it is at a deeper position, turn the LED light on for better vision.
Set the grease flow rate of the gun and start greasing.
When done, take the hose out and place it at a safe place. Remember to use safety goggles and hand gloves to avoid any unwanted situation.
