Cordless Grease Gun

I use it to grease 30 ft of early JD 750 drills with the mid row bander option. Normally greasing these two drills requires 5-6 tubes of grease on well over 100 zerks, which consumes 1-1/2 batteries. Like any Ni Cad battery, they gain power each time you recharge them during the first 4-5 charges. Like the instructions say, "never run the battery beyond where the tool starts to slow down. If you run them very low, the battery will be damaged." The long grease hose and hardned 4 jaw tip has been very good and the machined and hardned steel gears seem like they will last a long long time. You should remove that thick seal washer where the grease tube screws into the head, It is too thick and Does not allow enough thread engagegement of the grease tube and can damage the threads in the head. Removing that gasket allows the tube to screw in another 3 turns for a much tighter fit and nothing leaks without it.
