4.2 View of gas gauge data
4.2.1 Confirmation whether normal battery charge is possible.
(1) If TEMP value is 340K or less, RSOC value is confirmed and less than 100%.
(2) If an external power supply is connected, purple LED lights, and FLAGS doesn't become 99 or more (Please allow the time lag
of at least 10 seconds after connecting an external power supply).
If internal temperature is above 104 Fahrenheit (shown in Debug Mode pg 1-18), battery will not be charged.
4.2.2 Confirmation of battery failure.
(1) If LMD is 2000 or less and the value of CYCT is confirmed.
(2) Battery should be replaced when CYCT is 500 or more.
(3) After KVPX9 shuts down due to Low Battery (auto shutdown) when CYCT is 500 or less but battery is full charged.
Still, if LMD is 2000 or less, a defective battery or circuit malfunction can be at fault.
* The check on (MENU-SETUP-System-Auto Power Off) should be removed at this time to allow full battery discharge.
KVPX9 initialization after battery exchange.
It is necessary to initialize unit and study the gas gauge parameter. Initialization can be performed by either of the following:
(1) Leaving KVPX9 for half a day with the battery removed.
(2) Both ends of C140 are short-circuited with the battery removed (capacitor is discharged).
Initialization is possible when the value of LMD is 2787 [mA] or more.
Gas Gauge Status after battery exchange.
Data is not correct immediately after the battery exchange. Fully charge new battery then continue to operate KVPX9 until the sys-
tem auto shuts down before verifying Gas Gauge data..
*The check on (MENU-SETUP-System-Auto Power Off) should be removed at this time to allow full battery discharge.
The setting is preserved when
coming off the service mode.

TEMP contain the reported die temperature.
VOLT contain the reported battery voltage measured on the BAT pin.
RSOC reports the nominal available capacity as a percentage of the
last measured discharge value (LMD).
NAC increments during charge(Vsrp > Vsrn) if Voltage > EDVF
threshold and decrement during discharges (Vsrp > Vsrn).
CACD reports available capacity in the battery.
CACT reports available capacity in the battery, compensated for
both discharge rate and temperature.
LMD is the measured discharge capacity of battery from full to empty.
AI reports the magnitude of the average current through the sense
resistor
TTE reports calculated time-to-empty at the measured discharge rate.
TTF reports calculated time-to-full at the measured charge rate.
SI reports measured standby current through the sense resistor.
STTE reports calculated time-to-empty at the measured standby
current value.
MLI reports the measured Maximum load current through the sense
resistor.
MLTTE reports calculated time-to-empty in minutes at the Maximum
measured discharge rate.
SAE is the calculated energy available from the battery.
AP is the calculated power delivered during a discharge.
TTECP is the time-to-empty on minutes with a constant power load.
CYCL is the cycle count since the learning cycle.
CYCT is the cycle count since a full reset.
OSOC reports the compensated available capacity as a percentage
of the last measured value(LMD).
