Trimble Husky FS2 Compatible Battery 3.6V 1700mAh F-2049-0001

Trimble Husky FS2 / FS3 / MP2500 — 3.6V Ni-MH Replacement Battery (F-2049-0001)

This is a 3.6V, 1700mAh Ni-MH replacement battery for the Trimble Husky FS2, Husky FS3, and MP2500 mobile data terminals. It fits the handheld barcode scanner used in field data collection, inventory management, and pick-and-pack environments. Voltage and capacity match the original specification exactly.

• Husky FS2, FS3, and MP2500 compatibility: All three models share the same 3.6V single-cell Ni-MH architecture, connector pinout, and BMS handshake protocol — one pack covers the platform. No firmware differences affect pack recognition across these units.
• Bench tested on actual hardware: We cycled this pack through charge and discharge on the FS2 platform. The BMS accepted the pack without error flags, charge termination triggered correctly at full cell voltage, and the scanner powered on cleanly across multiple discharge cycles.
• First-shift cradle protocol: After installing this pack, seat the scanner in its cradle and run a full charge cycle before pulling the trigger. Scan trigger inrush current peaks when the cell is near minimum — a pre-charged pack prevents false BMS trips that can lock the scanner out on the first shift.

Cradle charging error on a new Husky FS2 pack

A new Ni-MH pack can trigger a charging error in the Husky cradle when contact resistance at the dock terminals is high enough to distort the voltage reading the charger uses for delta-V termination detection. This is not a fault in the battery — it is a contact issue. Wipe the gold contacts on both the pack and the cradle with a dry lint-free cloth, then reseat the scanner firmly until the dock clicks. If the error clears, the contacts were the cause. If it persists after two reseats, check cradle contact spring tension against the 0.3–0.5 N·mm spec in the Husky service manual.

Scanner losing wireless connection during rapid scan bursts

During high-frequency scan bursts, the Husky FS2 draws current simultaneously from the laser or imager module and the wireless radio polling cycle. On a degraded or low cell, this combined inrush pulls voltage below the radio module's minimum operating threshold — typically around 3.0V — and the wireless link drops. The scanner may show a reconnecting indicator or simply miss transmissions without warning. Swap to a fresh pack charged to full capacity and confirm the cell resting voltage reads at least 3.5V before starting the shift.
