Hi All,
We currently have 5 Haas machines and we are implementing a battery change procedure. I honestly can't see why I would want to pay for a service call for a $4.00 battery. Its like calling in an electrician to change a light bulb. Is there a simple easy way of doing this myself instead of feeling the sting of a service call? Can I just buy the external battery myself? Any help would be appreciated!
