Answer:
This replacement battery (they are not included) is compatible with eSSL biometric terminal models including the X990, UFace302, UFace602, EFace990, and MB160. It connects directly to the internal motherboard battery (they are not included) header to ensure backup power.
The eSSL 7.4V 2000mAh battery (they are not included) is designed for direct internal integration within specific eSSL multi-biometric attendance and access control hardware. Verified compatible terminal models include:
- eSSL X990
- eSSL UFace302
- eSSL UFace602
- eSSL EFace990
- eSSL MB160
The unit installs via its pre-terminated plug-in wiring lead, connecting directly to the dedicated DC backup battery (they are not included) socket on the reader motherboard. This provides automated switchover to secondary DC power when external mains supply drops, preventing sudden system reboots and attendance logging interruption.
