APS BCS1002 Barcode Scanner Replacement Battery 3.7V 2600mAh

APS BCS1002 — 3.7V Li-ion Replacement Battery

This 3.7V 2600mAh (9.62Wh) lithium-ion cell fits the APS BCS1002 handheld barcode scanner. It restores full scan and wireless function in retail, warehousing, and inventory environments where the original pack has degraded or failed. Voltage and connector match the OEM spec directly.

• BCS1002 platform fit: The BCS1002 runs a single-cell 3.7V rail with a BMS that monitors cell voltage and controls discharge cutoff. This pack matches that rail, so the scanner firmware recognises the battery and enables all functions — scan trigger, wireless radio, and display — without a calibration flag.
• Bench tested on actual hardware: We cycled this pack through rapid scan bursts while the wireless radio remained active. The BMS held stable cutoff voltage and did not trip on the combined inrush from the imager firing and the radio polling simultaneously.
• First-shift preparation: After installing, seat the scanner in its charging cradle and run a full charge cycle before the first pick-and-pack shift. Scan trigger inrush current peaks when the cell is near its minimum voltage — a fully charged pack avoids false BMS trips on the first use of the day.

Charging docks on the BCS1002 read pack voltage through spring contacts before enabling charge current. Oxidation or debris on the pack's contact pads raises resistance enough that the dock reads an out-of-range voltage and throws an error instead of charging. Wipe the gold contacts on the battery and the dock pins with a dry cloth, then firmly reseat the scanner. The charge indicator should switch to active within 30 seconds.

Scanner loses wireless connection mid-shift during rapid scan bursts

The BCS1002 fires the imager and polls its wireless radio in very close succession during fast scanning. When cell voltage sags under that combined load, the radio module drops its transmission before the imager does — the scan appears to complete but the data never reaches the host. This is a voltage-sag issue, not a radio fault. If the scanner reconnects immediately after the burst slows, the cell is the cause; a fresh, fully charged pack holds voltage above the radio's minimum threshold throughout a normal scan cycle.
