How do I Calibrate my SpringBoard Plus Batteries?
The SpringBoard Plus uses "Lithium Ion" batteries which never need to be calibrated.
If your battery charger is working correctly, your batteries will be fully charged in 6 hours.
Once the Battery Status Area shows 100%, you should get 8 hours of battery life before recharging the batteries.
Note: If you are using the internal Tracker headpointer, you can expect only 4 to 5 hours of battery life because the Tracker is always On.
Once the charger is disconnected from the device and the Battery Status area shows 100%, if you don't get 8 hours of battery life (or 4-5 hours with the Tracker in use) , then the batteries need replaced.
