Alemite’s 14.4-Volt Lithium-Ion Grease Gun combines heavy-duty performance with lithium-ion battery technology. Featuring a durable, ergonomic design, this grease gun is made to load easily, prime quickly and deliver up to 15 cartridges per charge. The tool’s lithium-ion technology offers constant output for fade-free power and five times less self-discharge compared to Ni-Cd options, according to the company. The battery can be charged at any time for any duration with no effect on battery life. The grease gun handles heavy loads easily, delivering grease at up to 10,000 psi. Its glass-fiber-reinforced nylon housing provides impact and wear resistance, and the grease gun’s patented airflow management system optimizes motor and transmission life. The tool’s optimized shape, weight and balance was designed to provide a comfortable grip with less physical strain. Also, the grease gun has three lubricant loading options – cartridge, bulk or suction. The series 586 kits include a charger and high-impact carrying case.
