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.
