About this replacement
Kronos InTouch 9000 — 11.1V Li-ion Replacement Battery (GS-1907)
This 11.1V, 2600mAh Li-ion battery replaces part number GS-1907 in the Kronos InTouch 9000 time clock system (model 8609000-018). It powers the device during normal operation and maintains backup functions when mains power is interrupted. Voltage and capacity match the original specification exactly.
- InTouch 9000 and 8609000-018 compatibility: Both model references share the same battery bay, connector pinout, and BMS handshake protocol. The GS-1907 format factor — 69.80 × 55.40 × 21.00mm — seats correctly in either unit without modification.
- Bench tested on actual hardware: We cycled this cell through charge and discharge on the InTouch 9000 platform. The BMS accepted the charge curve cleanly, protection circuits tripped at expected thresholds, and the unit held time without interruption across the test period.
- Data export before swap: Export all employee attendance records and enrollment data before removing the old battery. The InTouch 9000 stores timekeeping data and biometric enrollments in battery-backed RAM. Full power removal — even briefly — wipes that memory entirely on most firmware versions.
Why the InTouch 9000 loses all employee data after a battery swap
The InTouch 9000 uses battery-backed SRAM to retain employee records, punch data, and shift configurations. Unlike flash-stored settings, SRAM requires continuous voltage to hold its state — drop below the retention threshold and the contents clear immediately. This happens even during a fast swap if the internal capacitors drain before the new battery makes contact. Always export data to the Kronos Workforce Central or Dimensions server before touching the battery.
Fingerprint sensor unresponsive after battery replacement
The optical or capacitive fingerprint module in the InTouch 9000 requires a stable voltage above approximately 10.5V to initialise its processing core. A freshly installed battery shipped at storage charge — typically around 50% — may not provide enough headroom for the sensor to complete its startup sequence. The clock face and keypad may respond normally while the scanner stays dark or returns a continuous "Place Finger" error. Charge the unit fully before re-enrolling any employees or testing the sensor.
