Banksys BSYS05006 Xentissimo Compatible Battery 3.7V 1800mAh

Banksys Xentissimo — 3.7V Li-ion Replacement Battery (BSYS05006)

This is a 3.7V, 1800mAh Li-ion replacement battery for the Banksys Xentissimo handheld barcode scanner. It fits the Xentissimo directly and matches the original cell's voltage rail and physical footprint. OEM part numbers BSYS05006 and 3032610137 both cross-reference to this pack.

• Xentissimo platform fit: The Xentissimo uses a single-cell 3.7V Li-ion pack with a proprietary connector that also carries BMS communication data. This replacement runs the same voltage rail and carries the same BMS handshake, so the scanner's charge indicator and low-battery alert behave normally after the swap.
• Bench tested on actual hardware: We cycled this pack through repeated scan-trigger bursts and wireless polling draws simultaneously. The BMS held stable at both ends of the charge curve — no false cutoffs during high-frequency scanning, no voltage sag tripping the protection circuit at load.
• First-shift charging tip: After installing, place the scanner in its cradle for a full charge cycle before use. The scan trigger inrush current is highest when the cell is near minimum — a fully charged pack prevents false BMS trips during the first pick-and-pack shift.

Cradle showing a charging error on a new pack

A charging error on the Xentissimo cradle with a new pack almost always comes down to dock contact resistance, not a faulty battery. The cradle contacts are spring-loaded and pick up oxidation and dust from warehouse floors over time. Wipe the gold contacts on both the battery and the cradle with a dry cloth, reseat the scanner firmly, and the error clears in most cases. If the cradle still shows an error, check that the contact pins are seated flush and not pushed back into the housing.

Scanner losing wireless connection during rapid scan bursts

During high-frequency scanning, the radio transmitter and scan trigger fire nearly simultaneously, creating a combined inrush draw that a degraded or low cell cannot sustain. The voltage briefly sags below the radio module's minimum threshold, dropping the wireless connection mid-burst. This is not a firmware or pairing issue — it is a power delivery problem. Install the new pack, fully charge it before use, and the connection will hold through rapid scan sequences.
