About this replacement
Hoft & Wessel HW19200 Series — 3.7V Li-ion Replacement Battery (FBHWX26580)
This 3.7V 1800mAh Li-ion battery replaces part number FBHWX26580 in Hoft & Wessel handheld barcode scanners. It fits the HW19200, T26582, HW90250, HW90260, and additional models in the same platform family. Capacity is 6.66Wh, matching the original cell specification.
- HW19200 platform compatibility: These models share the same 3.7V power rail, battery footprint, and BMS handshake protocol. Swapping between them does not require a firmware change — the pack communicates directly with the scanner's onboard charge controller using the same pin-out.
- Bench tested on actual hardware: We ran this pack through simulated scan-burst cycles and wireless polling loads. The BMS held the output rail steady during combined inrush from the laser trigger and radio transmitter, with no false low-voltage cutoffs at full charge.
- First-shift charging tip: After installing, seat the scanner in its cradle and let it complete a full charge cycle before deploying it on the pick floor. Scan trigger inrush current is highest when the cell is near minimum — a fully charged pack prevents false BMS trips during the first heavy-use shift.
Cradle showing a charging error on a new pack
A charging error on a fresh pack almost always traces back to contact resistance between the battery terminals and the dock's charging pins, not a fault in the battery itself. Dust, oxidation, or residue on either surface raises resistance enough that the dock's charge controller reads an incomplete circuit. Wipe the gold contacts on the battery and the corresponding pins inside the cradle with a dry lint-free cloth, then reseat the scanner firmly. The error clears once contact resistance drops below the dock's threshold — typically under 100 milliohms.
Scanner stops reading barcodes mid-shift after a battery swap
If the scanner powers on but the imager or laser fails to fire, the cell voltage is likely sitting below the minimum threshold the scan engine needs — usually around 3.4V. This happens when a new pack is installed and immediately put into heavy use without a prior full charge. The BMS protects the scan engine by cutting power to it before the main CPU shuts down, so the device appears alive but won't read. Place the unit in the cradle, charge to 4.2V, then redeploy.
