Zebra SB1 TSD Scanner Replacement Battery 3.7V 1100mAh

Zebra SB1 TSD Scanner — 3.7V Li-Polymer Replacement Battery (82-158057-01)

This 3.7V, 1100mAh Li-Polymer battery replaces the OEM pack in the Zebra SB1 TSD handheld barcode scanner. The SB1 is a wearable scanner used in retail, warehouse, and logistics pick-and-pack workflows. Swap it when the original pack no longer holds a full shift's charge.

• SB1 TSD platform fit: The SB1 uses a slim Li-Polymer cell at 3.7V with a proprietary connector and BMS handshake that gates scan trigger and wireless radio power. A replacement must match the voltage rail and cell geometry exactly — the 82-158057-01 footprint at 53.92 × 35.70 × 6.25mm leaves no tolerance for a thicker aftermarket cell.
• Bench tested on actual hardware: We cycled this pack through repeated scan-and-transmit bursts on the SB1 platform. The BMS held stable across combined radio polling and scan trigger inrush without tripping low-voltage cutoff.
• First-shift preparation: After installing, seat the scanner in its cradle and run a full charge cycle before the first pick-and-pack shift. Scan trigger inrush is highest when the cell is near minimum state of charge — a fully charged pack prevents a false BMS trip on the first burst of the day.

Cradle showing a charging error on a new pack

The SB1 cradle reads pack state through the dock contacts on the battery's lower edge. If those contacts carry any residue from packaging, handling, or the old battery, the dock controller sees elevated resistance and flags a charge fault. This is not a cell fault — it is a contact issue. Wipe the gold contacts on the replacement pack and the cradle's pins with a dry lint-free cloth, reseat the scanner firmly, and the charging indicator should clear within 30 seconds.

Scanner dropping wireless connection during rapid scan bursts

The SB1 draws simultaneously from its wireless radio and the scan trigger during a high-frequency burst. If the cell voltage sags below the radio's minimum supply threshold mid-burst, the wireless module drops its access point association before the BMS trips the full pack. This happens most often on a partially depleted cell. Return the pack to the cradle until it reaches at least 3.9V before running high-cadence scanning sessions.
