Checking the Battery Pack
Battery charging will not start until the Fuel-Gauge shows that
less than 90% of the total power remains;
with this condition the battery pack will charge to 100% of its
capacity.
This protects the battery pack from being
over-charged or having a shortened life.
NOTE:
NOTE: The following figure hows the battery for the Model 370C, 750x, 755C, and 755Cs. The battery for Models 355x and 360x, do not have the storage switch, but the battery terminals are the same.
NOTE: Signal lines, not used in these steps,
are used for communication between the system and the battery.
The storage switch is used to control the power to the
internal microprocessor of the battery.
The storage switch should be
set to off (0) only when the battery is going to be kept in storage
for more than two months.
If the voltage is still less than + 8.0 Vdc after the recharging,
replace the battery.
If the resistance is not correct, replace the battery pack.
If the resistance is correct, replace the DC/DC card.
