Hoft & Wessel HW19200 Compatible Battery 3.7V 3600mAh

Hoft & Wessel HW19200 / T26582 Series — 3.7V Li-ion Replacement Battery (FBHWX26580)

This 3.7V 3600mAh Li-ion pack replaces the OEM battery in the Hoft & Wessel HW19200, T26582, HW90250, HW90260, and compatible models. These scanners run in retail, warehouse, and inventory environments where the battery takes a constant hit from scan triggers, wireless polling, and display backlight. When the original cell degrades, scan reliability drops before the pack fully dies — this replacement restores full operating voltage to the scanner's power rail.

• HW19200 / T26582 platform fit: These models share the same 3.7V single-cell architecture, battery connector pinout, and BMS handshake protocol — which is why one pack covers the full range. Swapping between them needs no modification.
• Bench tested on actual hardware: We cycled this pack through scan-trigger inrush and simultaneous wireless polling loads. The BMS held cutoff thresholds correctly and did not trip false low-voltage faults during combined draw events.
• First-shift prep for pick-and-pack: After installing this pack, seat the scanner in its cradle and run a full charge cycle before the shift starts. Scan trigger inrush is highest when the cell is near minimum voltage, and a pre-charged cell prevents false BMS trips on the first pick run of the day.

Cradle showing a charging error on a new pack

Charging docks on the HW19200 series read contact resistance before opening the charge circuit. If the gold contacts on the battery or cradle have oxidation or residue from handling, the dock sees an open circuit and flags a charge fault. This is not a faulty pack — it is a contact issue. Wipe the battery contacts and the cradle contacts with a dry cloth, reseat the scanner firmly, and the charging indicator should clear within 30 seconds.

Scanner losing wireless connection during rapid scan bursts

During a fast scan sequence, the imager trigger and the wireless radio fire almost simultaneously, creating a combined inrush spike on the battery's output. A degraded or low-charge cell sags in voltage under that combined load, which causes the wireless module to drop its connection before the BMS cuts off. The scanner reconnects once load drops, which looks like an intermittent radio fault but is actually a voltage sag event. Keeping the pack above 3.5V at the start of a scan burst prevents the sag from crossing the radio module's minimum supply threshold.
