Preparation and Hardware Safety Protocols
Installing the eSSL 7.4V 2000 mAh internal rechargeable lithium-polymer battery pack (SKU: KTI90002001EIOB) requires strict adherence to standard electronic servicing procedures. Before initiating the installation or replacement process, disconnect the biometric time and attendance terminal from its primary mains electrical power supply and remove the external DC power adapter. De-energizing the terminal eliminates the risk of accidental electrical short circuits across the motherboard during internal servicing.
Ensure the workstation or servicing area is free of moisture, static discharge, and conductive debris. Handle the lithium-polymer battery pack carefully by its main casing rather than pulling or straining the attached wiring leads. Note that product model, make, and visual appearance are subject to change without prior notice across production runs.
Biometric Terminal Hardware Compatibility
This 7.4 V DC backup battery is engineered specifically for internal chassis integration into compatible eSSL biometric time, attendance, and access control readers. The pack supplies uninterrupted internal DC backup power during utility power fluctuations and outages. Verified terminal compatibility includes:
- eSSL X990: Biometric fingerprint time and attendance terminal.
- eSSL UFace302: Multi-biometric facial and fingerprint recognition device.
- eSSL UFace602: Multi-biometric attendance and access control terminal.
- eSSL EFace990: High-capacity facial recognition terminal.
- eSSL MB160: Multi-biometric identification and attendance reader.
Step-by-Step Terminal Integration Procedure
The eSSL battery pack features an integrated wiring lead terminating in a dedicated terminal connector plug designed for direct plug-and-play installation into the attendance reader motherboard. No wire splicing or external soldering is required when replacing a degraded power unit in compatible hardware.
- Carefully open the biometric terminal enclosure by removing the rear housing retention screws to access the internal electronics chassis.
- If replacing a degraded pack that triggers sudden device shutdowns upon utility power disconnection, gently disconnect the existing wiring harness from the internal motherboard header socket.
- Position the replacement 7.4V 2000 mAh lithium-polymer battery pack securely into the terminal internal chassis compartment without pinching or twisting the wiring lead.
- Align the connector plug with the keyed internal battery header on the attendance reader motherboard and push firmly until fully seated.
- Reassemble the terminal housing, ensuring all internal harnesses are clear of enclosure seams, and reinstall the casing screws securely.
Commissioning and Operational Verification
Following mechanical assembly, reconnect the external power supply to the attendance terminal to verify regular charging operation. Allow the biometric reader to charge the 2000 mAh capacity battery pack via the internal charging circuit. To verify proper failover functionality, disconnect the primary external power cable; the biometric terminal should remain continuously operational, maintaining optical sensors, system memory, and display backlighting without rebooting or shutting down.
