CipherLab 8001 Barcode Scanner Compatible Battery 3.7V 750mAh

CipherLab 8001 / 8300-L / CPT8071 — 3.7V Li-ion Replacement Battery (100845)

This 3.7V, 750mAh Li-ion cell replaces the original battery in the CipherLab 8001, 8300-L, and CPT8071 handheld barcode scanners. These are mobile data collection devices used in warehouse, logistics, and retail pick-and-pack environments. OEM part numbers covered: 100845, BA-80S700, KB1B3770000L3, and 33-KB1B3770000L3.

• 8001 / 8300-L / CPT8071 platform fit: All three models share the same 3.7V battery rail, physical form factor, and BMS handshake protocol — that is why a single cell covers them. The connector pinout and thermistor line are identical across the platform, so the pack seats and communicates without modification.
• Bench tested on actual hardware: We cycled this pack through charge, idle, and active scan-trigger loads on the bench. The BMS held voltage within spec across the cycle and did not trip on the combined inrush from the laser and wireless radio firing together.
• First-shift preparation for scan-heavy environments: After installing the new pack, place the scanner in its cradle and run a full charge cycle before pulling it into active picking. Scan trigger inrush is highest when the cell is near minimum charge — a pre-charged cell prevents the BMS from tripping on the first heavy burst of the shift.

Cradle showing a charging error after fitting a new pack

This error appears when the dock detects abnormal resistance at the charge contacts — not a fault with the cell itself. Dock contacts on high-use cradles accumulate oxidation and debris that spike contact resistance above what the charger expects from a new, low-impedance pack. Wipe the gold contacts on both the battery and the cradle with a dry cloth, then reseat the scanner firmly until the dock clicks. The charging indicator should switch to normal within a few seconds of a clean connection.

Scanner reads barcodes intermittently or not at all after a battery swap

If the scanner powers on but the laser or imager fires weakly or fails to trigger a read, the cell voltage is likely still below the minimum the decoder board needs to process a scan. At voltages below 3.4V the imager draws more current than the partially charged pack can sustain cleanly, causing brownouts at the decoder. Place the unit back in the cradle and charge to full before returning it to use. Once fully charged, a clean read on a standard 1D or 2D barcode confirms the decoder is receiving adequate voltage.
