At the third step, you should discharge the battery from the fully charged (100% SoC) to the fully discharged
state. The discharge current should be equal (or as close as possible) to the following calculated value:
where:
C – battery’s rated capacity in ampere-hours (set for CAPACITY parameter, see Section IX),
T – battery’s nominal discharge rate in hours (set for NOMINAL_RATE, see Section IX).
Please note that the discharge process can take a significant amount of time (up to T hours – see the
I
dis
formula above), which depends on the actual health of your battery (usually the discharge rate T is 20
hours).
When battery voltage drops below the Discharge Voltage value (see Table 1 below), the state switches
to «Discharged» with the flash sequence RRGGGG. You should start charging the battery as soon as
possible after it is fully discharged. To extend the battery’s life, never leave it discharged for a prolonged
time period.
Full Synchronization ends when the battery is fully charged (see X.1 for details about full charge), state
of health will be updated, state of charge will be set to 100% and the consumed Ah will be set to 0Ah.
FULL_SYNC will be automatically set to OFF (YD:FULL_SYNC or FULL_SYNC, see Section IX).
The Device’s will emit «Done» flashing sequence (six GREEN flashes) for a period of an hour for your
convenience (you don’t need to wait while the Device stops emit this sequence, you can turn the Device
off if required).
We recommend performing the Full Synchronization once a year. Full Synchronization is as well required
each time you switch on the calculations, or reset the Device, or alter the nominal capacity value in Battery
Monitor settings, and then connect the Device to a non-new battery (i.e. with SoH definitely less than
100%).
If you do not need the SoH value, you could just ignore the Full Synchronization. Please note that in this
case, the SoH value will remain constant, and will not change unless you perform a Full Synchronization.
Moreover, if you use the Device with a battery of more than several years old, and/or the battery
was maintained in the incorrect manner (e.g. repeatedly discharged below the specified limit, kept
