Introduction
As Pro controllers get older, the internal lithium batteries will naturally start to age as well. As they age, their maximum capacity will slowly decrease, but the controller will continue to expect the same maximum charge. This can lead to false charge percentages and unexpected shutdowns, given enough time.
To combat this issue, we recommend using the Bat Cal utility every 6-12 months. The Bat Cal process can take up to 24 hours to complete, so please plan accordingly. The utility will charge the batteries to full, drain the batteries completely and then charge them again to take an accurate measurement of the batteries' actual capacity.
This feature is only available in BoxScore 3
Using the Utility
To access the Bat Cal utility, go Controller > Maintenance > Diagnostics > Battery
Simply press the Start button to initiate the battery calibration process.
As the process runs, BoxScore will keep you notified about its progress in the text area at the bottom of the screen. The Discharging section to the right will give you a good indication of your controller's minimum possible battery life. During the discharging phase, every internal component will be powered on including the WiFi and Cellular modems and the internal cooling fan to emulate the maximum possible load.
When the process is complete, the controller will inform you visually using the text area at the bottom of the screen.
