Honeywell 1952GRS-2-31886 3.7V Replacement Battery 2400mAh

Honeywell Granit XP 1990iSR / Xenon 1952 Series — 3.7V Li-ion Replacement Battery (BAT-SCN05)

This 3.7V, 2400mAh Li-ion cell replaces the original pack in the Honeywell Granit XP 1990iSR, Xenon 1902GHD, Xenon 1952, and 1952GRS-2-31886 (REV B) barcode scanners. It matches the OEM voltage rail and physical footprint so the pack seats correctly in the battery bay. Capacity is 2400mAh (8.88Wh), matching the original specification.

• Multi-model fit — Xenon and Granit XP platforms: These scanners share the same 3.7V battery bay, connector pin layout, and BMS communication protocol, which is why one pack covers the full model range. The BMS handshake on each device reads cell chemistry and voltage before enabling the scan trigger.
• Bench tested on actual hardware: We cycled this pack through repeated scan-trigger and wireless radio draw events. The BMS held cutoff thresholds correctly at both low-charge and full-charge states, with no false trips during back-to-back scan bursts.
• First-shift preparation on cradle-charged scanners: After installing, place the scanner in its charging cradle for a full charge cycle before deploying on the floor. The scan trigger inrush current peaks when the cell is near minimum — a pre-charged cell prevents false BMS trips on your first pick-and-pack shift.

Cradle showing a charging error on a new pack

Honeywell charging cradles use contact resistance to verify a valid battery is seated before starting a charge cycle. If the dock contacts or the battery terminals have any oxidation or debris, the cradle reads an open circuit and throws a charging error. This is not a fault with the new cell — it is a contact issue. Wipe the gold contacts on both the battery and the cradle dock with a dry cloth, reseat the scanner firmly, and the error clears. The cradle should begin charging within 10 seconds of a clean reseat.

Scanner losing wireless connection during rapid scan bursts

During a rapid scanning sequence, the scanner draws current from two sources simultaneously — the imager or laser, and the wireless radio maintaining its Bluetooth or 802.11 link. The combined inrush can push instantaneous draw above the BMS threshold if the cell is below 3.5V. The BMS momentarily reduces output to protect the cell, and the radio drops its connection first because it is lower priority than the scan trigger. Keep the cell above 3.6V during active shifts and the connection stays stable through sustained burst scanning.
