CipherLab 1166 Barcode Scanner Compatible Battery BA-000700 3.7V

CipherLab 1166 / 1266 Series — 3.7V Li-ion Replacement Battery (BA-000700)

This is a 3.7V 700mAh Li-ion replacement battery for the CipherLab 1166 and 1266 mobile barcode scanners. It also fits the CL1160 and CL1266 variants that share the same OEM part number, BA-000700. All four models use identical battery housings and connector pinouts, so one cell covers the full group.

• 1166, 1266, CL1160, CL1266 compatibility: These four models share the same 3.7V power rail, physical form factor, and BMS handshake protocol. The battery management circuitry on each device reads the same protection thresholds, so the BA-000700 cell communicates correctly across all four without any firmware workaround.
• Bench tested on actual hardware: We ran this pack through charge and discharge cycles on a CipherLab 1166 unit. The BMS accepted the cell without triggering an over-voltage fault on initial charge, and the scan trigger drew current normally across the full charge window.
• First-use cradle cycle: After installing, place the scanner in its cradle and run a full charge cycle before the first pick-and-pack shift. The scan trigger draws its highest inrush current when the cell sits near minimum charge — a pre-charged pack prevents false BMS trips on the opening burst of the first shift.

Cradle showing a charging error on a new BA-000700 pack

CipherLab cradles read the battery through spring-loaded dock contacts on the base of the scanner. If those contacts carry oxidation or debris from the old pack, the cradle can't confirm a valid cell and throws a charging error even though the new battery is fine. Wipe the gold contacts on both the scanner and the cradle with a dry cloth, reseat the unit firmly, and check that the charge indicator activates within 10 seconds. If the error persists, press the scanner down while the cradle light is solid — intermittent contact is usually the cause, not the cell.

Scanner not reading barcodes immediately after battery swap

The laser or imager module in the 1166 needs the cell voltage above roughly 3.5V to fire at full power — below that, scan attempts fail silently or return partial reads. A newly installed replacement battery that has been in storage may sit at 3.3V or lower, which is enough to boot the scanner but not enough to sustain the optical module under trigger load. Put the scanner on the cradle for a full charge before scanning production barcodes. Once the cell reaches 4.2V, scan performance returns to normal.
