Cordless grease gun for my auto shop

I own a small automotive shop and I am constantly using my old fashioned hand operated grease gun for all of my lubrication needs. I know there has to be some sort of gadget that automatically with run a grease gun for me. The old hand operated gun is too slow. Mainly I am greasing zert points on trailers, automobiles and small construction equipment. I only need to have the grease capicity of regular grease gun. I know of the models that run from a larger grease source. I have to get a car lubed and out of my shop as quickly as possible. Is there a tool out there for this?

Great question. The simple answer is the Lincoln Lubrication 12 volt cordless grease gun. This tool comes with a rechargable 12 volt battery, a molded carrying case and a 30" flexible hose. This cordless grease gun using convential grease cartridges just like your hand held model and will automatically inject the grease with having to physically squeeze a handle.
