IDEMIA MorphoTablet 2 Compatible Battery TLp050A1 3.8V 4900mAh

IDEMIA MorphoTablet 2 — 3.8V Li-Polymer Replacement Battery (TLp050A1)

This is a 3.8V, 4900mAh (18.62Wh) Li-Polymer battery for the IDEMIA MorphoTablet 2 biometric tablet. It replaces OEM part TLp050A1 and restores power to devices used in fingerprint scanning, identity enrollment, and government verification workflows. If your tablet no longer holds a charge through a full enrollment session, this is the direct OEM-matched replacement cell.

• MorphoTablet 2 platform fit: The MorphoTablet 2 uses a slim 3.00mm Li-Polymer cell to stay within its sealed chassis profile. The TLp050A1 cell matches the voltage rail and connector pinout the tablet's charge IC expects — swapping in a mismatched cell triggers BMS rejection at the hardware handshake level.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the MorphoTablet 2 platform. The BMS accepted the cell without fault flags, and the charge IC completed a full CC/CV charge cycle without cutoff errors.
• Post-swap fuel gauge reset: After fitting this battery, run the tablet down to automatic shutoff — do not manually power it off — then charge uninterrupted to 100%. The MorphoTablet 2's fuel gauge IC calibrates against discharge curves, and skipping this step leaves it reading against the old cell's profile, causing the percentage display to drift immediately after installation.

MorphoTablet 2 shutting down at 15–25% during active biometric scans

The MorphoTablet 2 draws a combined load spike when the fingerprint scanner fires alongside the display and wireless radio — this hits the battery simultaneously from multiple subsystems. If the cell voltage drops below the BMS cutoff threshold under that spike, the tablet shuts down even though the fuel gauge still shows charge remaining. A degraded original cell hits this threshold much earlier in the discharge curve. A fresh TLp050A1 cell holds the voltage rail above the cutoff through that combined load. After replacement, run one full calibration cycle so the fuel gauge maps the new cell's voltage curve accurately before field deployment.

Battery percentage jumping or dropping unexpectedly after the swap

This happens because the fuel gauge IC stored calibration data from the old, degraded cell — it does not automatically reset when a new battery is connected. The IC uses the previous cell's internal resistance and discharge curve to estimate state of charge, so readings on the new cell are immediately inaccurate. Fix it by letting the tablet discharge fully to automatic shutoff, then charging without interruption to 100%. After one complete cycle, the fuel gauge re-anchors its algorithm to the new cell and percentage readings stabilise.
