William,

The BDI adjustment is correct. Explanation of adjustment is listed below. The decrement time is used when the lift barely stops. The lift is constantly used non stop. I would not worry about that setting.

BDI Adjustment (Later Models)
(Range - First Digit 1-5)(Range - Second Digit 3-7)
This parameter setting allows for adjustment to improve the accuracy of the battery discharge indicator in the dash display.
This first digit adjusts the charged setting. Increasing the setting will increase the battery voltage or specific gravity required for the indicator to show full. If the indicator consistently reads low with fully charged batteries, decrease this setting.
The second digit adjusts the discharged setting. Increasing the setting will increase the battery voltage or specific gravity level required for the indicator to show empty. If the indicator consistently shows lift interrupt too soon, decrease this setting.
A setting of 35 is the recommended starting point for flooded batteries. A setting of 37 is the recommended starting point for maintenance-free batteries. Further adjustments may be used to fine-tune the BDI accuracy.
