Reflecta X7-Scan Compatible Battery 3.7V 1000mAh Li-ion

REFLECTA X7-Scan — 3.7V Li-ion Replacement Battery

This is a 3.7V, 1000mAh Li-ion replacement battery for the REFLECTA X7-Scan portable scanner. It slots into the X7-Scan to restore power when the original cell no longer holds a charge. Capacity is 1000mAh (3.7Wh) — identical to the factory specification.

• X7-Scan platform fit: The X7-Scan uses a compact single-cell Li-ion pack at 3.7V nominal. The cell dimensions — 53.00 × 33.90 × 5.70mm — match the original bay geometry. The BMS handles charge termination and discharge protection at the cell level, so the host device's charge circuit sees the same impedance profile as the factory cell.
• Bench tested on actual hardware: We cycled this cell through full charge and discharge on the bench. The BMS held cutoff at the correct low-voltage threshold and accepted charge termination without fault. No thermal event was recorded during the charge cycle.
• Fuel gauge recalibration on first cycle: On first use after installation, disable fast charging if the option is available and run one complete discharge-to-charge cycle. This gives the fuel gauge IC a clean reference point against the new cell's discharge curve before it begins reporting state of charge to the OS.

Sudden shutdown at 20–30% on the X7-Scan after a cell swap

A new cell has a slightly different voltage-versus-capacity curve than the aged cell it replaces. The fuel gauge IC on the X7-Scan was calibrated against the old cell's curve. When the scanner draws a burst of current — during a wireless sync or a high-resolution scan — the new cell's voltage briefly dips below the BMS cutoff threshold even though the displayed percentage reads mid-range. The BMS trips and the device shuts down. One full discharge-charge cycle recalibrates the coulomb counter and eliminates most of these early shutdowns.

X7-Scan shows incorrect battery percentage after replacement

The fuel gauge IC stores a learned model of the battery's discharge curve in memory. Swapping the cell does not reset that model automatically. The IC continues applying the old curve to the new cell, which causes the percentage display to jump, stall, or read incorrectly — especially below 40% and above 80%. To force a recalibration, drain the battery until the device shuts off on its own, then charge uninterrupted to 100%. After one full cycle the gauge IC updates its reference and the percentage reporting stabilises.
