BCS1002 Barcode Scanner Compatible Battery 3.7V 3400mAh

APS BCS1002 — 3.7V Li-ion Replacement Battery

This 3.7V 3400mAh (12.58Wh) lithium-ion cell replaces the factory battery in the Motorola/Symbol BCS1002 handheld barcode scanner. It fits the BCS1002 form factor directly, matching the original connector and BMS communication protocol. Built for commercial scan environments — retail floors, warehouse pick lines, and inventory operations running multiple shifts.

• BCS1002 platform fit: The BCS1002 uses a single-cell 3.7V architecture with a proprietary BMS handshake through the cradle dock. This pack mirrors that voltage rail and communication interface, so the host device recognises the battery immediately on insertion without throwing an authentication error.
• Bench tested on actual hardware: We cycled this pack through repeated scan-trigger and wireless radio draws simultaneously — the two highest inrush events on a BCS1002. The BMS held stable across cold-start and mid-shift pulls without triggering an over-current cutoff.
• First-shift preparation: After installing this pack, seat the scanner in its charging cradle and run a full charge cycle before the first pick shift. Scan-trigger inrush is highest when the cell is near minimum voltage, and a fully charged cell prevents a false BMS trip on the first heavy burst of the day.

Cradle showing a charging error on a new pack

A new battery sometimes triggers a charging fault on the BCS1002 dock even though nothing is electrically wrong with the cell. The most common cause is contact resistance between the pack's gold pads and the cradle's spring pins — oxidation or debris on either surface breaks the low-current handshake the dock uses to identify the pack. Wipe the battery contacts and the cradle pins with a dry lint-free cloth, then reseat the scanner firmly. If the error clears, the pack is communicating correctly and charging will proceed normally.

Scanner loses wireless connection during rapid scan bursts

During fast-scan sequences the BCS1002 draws simultaneously from the imager and the wireless radio — two inrush events stacked on a single cell. If the cell voltage sags below the radio module's minimum during that combined draw, the wireless stack drops and reconnects, which operators see as a freeze or missed transmission. This is more likely when the battery is below 20% charge. Keep the pack above 3.6V at the start of each shift to give the radio module enough headroom to hold its connection through high-frequency scan bursts.
