When should I calibrate my batteries?
You should calibrate your batteries if the HH Control Panel on your unit indicates a max error of greater than 2%. To check the max error of the battery, go to START, PROGRAMS, HHUTILITIES, HH Control Panel. Click the Information Button, then click the BATTERIES button. On the upper right, select the battery radio button of the battery you wish to look at. The “Max Error” is shown on this screen.
Note: Only calibrate batteries when they need it. Calibrating a battery unnecessarily will increase the cycle count and thereby reduce the battery life.
What are the Over Temperature and Over Voltage boxes in the HH Control Panel?
To insure the safety of the Hammerhead Computer at all times, the HH Control program monitors battery temperature and voltage. If a malfunction ever causes either of these values become too high, the computer will shut down to prevent any permanent damage to the computer.
