Most Powerful Battery-Powered Grease Guns

Most mechanics know how difficult it can be getting a traditional grease gun positioned under a car, attached to the lube nipple, and then squeezing a hand-powered pump. Squirting heavy viscosity automotive grease into an automotive fitting is like trying to suck vaseline through a straw. With the widespread application of high voltage, cordless rechargeable tools, a new generation of cordless grease guns have entered the market for professional and weekend auto mechanics.

Zee-Line 19.2V

The Zee Line 19.2 V cordless, battery-powered grease gun provides a high-flow rate, high-pressure application that simplifies the process of greasing an automotive chassis. The tool has the largest voltage battery in the tool category and, as a result, delivers the right amount of grease under the most extreme conditions. One of the most useful features of the tool is the 30-inch whip hose. The long hose allows the mechanic to reach even the most difficult lube nipples easily, and still deliver the right amount of lubrication. This unit comes with a one-hour charger and a polyvinyl storage case.

Lincoln 18V PowerLuber

Lincoln manufactures a full line of professional quality hand and power tools for mechanics. They have created two battery-powered grease guns, each of which deserve mention in the list of the best cordless grease guns. Lincoln's heavy-duty 18V battery powered PowerLuber lasts 30 per cent longer than their 14.4V unit. The tool is well designed and balanced, including a comfortable moulded grip. This tool has a two-speed gear box to deliver high pressure or high volume output. The tool's motor features overload protection circuitry, and delivers up to 10 standard size grease cartridges on one battery charge.

Lincoln 14.4V PowerLuber

Lincoln's original professional cordless grease gun, their 14.4V PowerLuber, is the perfect balance of weight, power and durability for the average mechanic. This unit also features Lincoln's two-speed switch, so the grease gun can deliver for high pressure or high volume. Until the introduction of 18V power tools, the 14.4V line was the standard for professional tradesmen. The tool features a charging system that monitors the battery condition and doesn't overcharge it, which can destroy the rechargeable pack. This unit has a comfortable, ergonomic grip and the tool is balanced to provide optimal user control and comfort.

Milwaukee 12V Tool

The Milwaukee is one of the last American tool manufacturers, and their m12 line of 12V lithium ion battery-powered tools outperforms many other tool manufacturers' larger voltage tools. Lithium ion batteries charge faster, weigh less and deliver a more consistent voltage than less expensive nickel metal hydride or nickel cadmium batteries. Milwaukee's cordless grease gun delivers grease at over 8,000 PSI, and can pump up to seven cartridges on a full charge. The tool is only 3.27kg., and has a 36-inch long spring guard hose for reaching obscurely mounted lube nipples.
