William,

After looking up your lift, the year is 2007. The tool required to connect with a computer is ETACC. You would use the same cable. You should be able to complete the battery adjustments through the display. I am attaching a list of steps that you may have already done.
The technician can scroll through the menu using the
up [1] or down [2] arrows and select the desired function
by pressing the [4] button. Each menu selection has a
list of submenu functions. The submenus are viewed
and items selected by scrolling through the menu in the
same manner as described above.
To exit a selected function and return to the previous
function, press the [3] button. Pressing the [3] button
multiple times will return the technician to the operator's
driving mode. Try this and let me know. Thanks.
