This is the battery replacement for all the Portable machines.  If you are handy all it takes is to unscrew a few screws and separate the Generator from the base and expose the battery compartment.  Then you just un plug the old battery and plug in the new one and put it back together and charge up the battery.  If you prefer us to do this you can take advantage of our Refurbishment Program where we will clean, inspect and test your machine as well as add any additional upgrade available for your product.
