SYNCHRONIZING LINK 2000 METERS
TO A CHARGED BATTERY
A charged battery has zero A hrs removed. Synchronizing your LINK 2000 Meter
to read zero when the battery is charged ensures that you always know the net number of
A hrs removed. The following charged parameters indicate when a charging system has
put as much energy into a battery as it normally can. Your LINK 2000 Meter must
be synchronized to the battery according to these parameters.
CHARGED PARAMETERS
WHEN IS THE BATTERY FULL?
MULTIPLE STAGE CHARGING SYSTEMS
If you are using the Freedom charger, the battery is charged when the system
switches to the Float cycle. If another manufacturer's charging system is also being used
it should be adjusted so the transition from Acceptance Charging to Float will occur when
the charging current, at the Acceptance Voltage (14.4V Typ.), drops to below 2% of the
battery capacity. (See description on previous page about the Ideal Charge Curve.)
CONSTANT VOLTAGE CHARGING SYSTEMS
Constant voltage charging systems have restored as much charge to a battery as
they can when the voltage reaches the maximum regulation point (typical 12V system
is set at 13.8V) and the charging current drops to less than 1% of the battery capacity. It
can take more than 8 hours for a battery to reach this state of charge. If you are using
an engine driven charging system and trying to limit engine run time, you probably will
charge only until the current drops to 5% or 10% of capacity. The LINK 2000 Meter
should be synchronized to which ever of these charge levels is reached in normal operation.
USING SPECIFIC GRAVITY
Accurate battery current measurement is necessary to determine the charged
parameters in the two previous methods. Specific gravity of the battery can also be
used to determine the charge level of a battery. Regardless of the charging system a battery
is charged when the specific gravity shows no increase for three hours, when measured at
half hour intervals. Typical specific gravity @ 77
0
F for a fully charged liquid electrolyte
battery is 1.265
+ 0.050.
TWO WAYS TO SYNCHRONIZE
There are two ways to synchronize your LINK 2000 Meter to a battery that has
met the charged parameters:
1) Install the LINK 2000 on a charged battery and it will be in sync.
2) If the LINK 2000 is installed on a partially charged battery, simply charge until the
charged parameters are met. The LINK 2000 will begin counting up and will display
