Keyence BT-600 Replacement Battery 3.7V 1100mAh Li-ion

Keyence BT-600 / BT-1000 Series — 3.7V Li-ion Replacement Battery (BT-B60)

This 3.7V 1100mAh Li-ion pack replaces the OEM BT-B60, BT-B10, BT-LIBS, and BT-WB2 batteries. It fits the Keyence BT-600, BT-1000, BT-1010, and BT-1500 handheld barcode scanners used in warehouse, retail, and industrial inventory environments. Voltage and cell dimensions match the original spec exactly.

• BT-600 and BT-1000 series compatibility: These models share the same 3.7V single-cell architecture, connector pinout, and BMS handshake protocol — one pack covers the full range without modification.
• Bench tested on actual hardware: We cycled this pack through repeated scan-burst loads and wireless polling draws. The BMS held voltage within the expected window and did not trigger false low-voltage cutoffs under combined radio and imager current draw.
• First-shift preparation: After installing, seat the scanner in its cradle and run a full charge cycle before the first pick-and-pack shift. The scan trigger inrush current peaks when the cell sits near minimum charge, and starting the shift on a full cell prevents spurious BMS trips during the first burst sequence.

Cradle showing charging error on a new pack

A charging error on a fresh pack almost always comes down to contact resistance at the dock terminals, not a fault in the battery itself. Dust, oxidation, or a slight misalignment between the pack contacts and cradle pins interrupts the charge handshake. Wipe both the battery contacts and the cradle pins with a dry cloth, then reseat the pack firmly until it clicks. If the error clears within 30 seconds, contact resistance was the cause — the cell is fine.

Scanner losing wireless connection during rapid scan bursts

The BT-600 draws current from two sources simultaneously during a rapid scan burst: the imager or laser and the wireless radio. On a partially depleted cell, that combined inrush can pull voltage low enough that the radio module drops its connection before the BMS trips. The symptom looks like a wireless fault but the root cause is voltage sag under combined load. Keeping the cell above 3.5V under load — which means charging before voltage drops to the low warning threshold — prevents the drop-out entirely.
