Verified eSSL Terminal Model Compatibility
The eSSL 7.4V 2000mAh attendance reader battery (SKU: KTI90002001EIOB) is engineered specifically for direct hardware integration across select eSSL biometric time, attendance, and access control terminals. Designed as a dedicated internal DC backup power supply, this rechargeable lithium-polymer battery pack matches the factory electrical and mechanical tolerances of standard enterprise terminals deployed across industrial and commercial facilities.
This replacement pack provides verified plug-and-play compatibility with the following eSSL hardware series:
- eSSL X990: Standalone fingerprint time and attendance terminal.
- eSSL UFace302: Multi-biometric facial and fingerprint recognition reader.
- eSSL UFace602: High-capacity facial recognition and RFID attendance terminal.
- eSSL EFace990: Facial recognition and biometric access control terminal.
- eSSL MB160: Multi-biometric identification time attendance terminal.

Electrical Matching and Connector Architecture
Proper system function depends on strict adherence to device power profiles. This unit supplies a nominal output voltage of 7.4 V with a rated capacity of 2000 mAh. Built as a lithium-polymer battery pack, it includes an integrated wiring lead terminating in a keyed connector plug designed to seat securely into the dedicated internal battery header located on compatible eSSL motherboard assemblies.
The plug-in lead assembly eliminates the need for soldering or modification of the reader casing, ensuring field service technicians can complete replacements during scheduled maintenance windows with minimal equipment downtime. The total packaged item weight is 0.4 kg, matching standard internal device weight envelopes without overloading terminal wall mounts or enclosures.
Operational Backup and Replacement Identifiers
This battery pack is intended to serve as the direct DC power reserve when incoming AC mains power experiences interruptions, blackouts, or voltage instability. Over operational life cycles, biometric units face end-of-life battery degradation. Facilities teams should verify compatibility and replace depleted battery packs when experiencing the following field conditions:
- The biometric reader shuts down immediately when disconnected from its external AC power adapter.
- The reader reboots unexpectedly during momentary mains voltage fluctuations.
- The terminal motherboard fails to maintain a backup charge, leading to lost punch synchronizations during outages.
