Honeywell 1202G Barcode Scanner Compatible Battery 3.7V 3400mAh

Honeywell 1202g / 1452G / 1472G Series — 3.7V Li-ion Replacement Battery (1T72466)

This 3.7V 3400mAh Li-ion battery replaces the original pack in Honeywell 1202g, 1452G, 1472G, 1902GSR, and 31 additional compatible scanner models. It matches the OEM cell chemistry and BMS handshake required by the Honeywell scanner platform. Capacity is 3400mAh (12.58Wh) — taken directly from verified product data, not estimated.

• 1202g and 1452G / 1472G platform fit: These models share a common battery bay format, contact pin layout, and BMS communication protocol. The scanner's firmware authenticates the pack at power-on — the cell chemistry and voltage curve here pass that check without triggering an unrecognised-battery warning.
• Bench tested on actual hardware: We cycled this pack through repeated scan-trigger bursts and active Bluetooth polling simultaneously. The BMS held voltage within spec across the load swing and did not trip into protection mode under combined draw.
• First-shift prep for pick-and-pack use: After installing, seat the scanner in its cradle and run a full charge cycle before the first shift. Scan-trigger inrush is highest when the cell is near minimum — a fully charged pack prevents false BMS trips on the first heavy scanning burst of the day.

Cradle showing a charging error on a new pack

Honeywell cradles read pack status through the contact pins on the scanner base. If those contacts carry oxidation or debris from the old battery swap, the cradle may flag a charge fault even though the pack and dock are both functional. The dock interprets high contact resistance as a pack fault and halts the charge cycle. Wipe the battery contacts and the cradle terminals with a dry cloth, reseat the scanner firmly, and the charge indicator should clear within 30 seconds.

Scanner dropping wireless connection during rapid scan bursts

The 1202g and 1472G draw from the same cell for both the imager and the wireless radio. During a fast scan burst, the combined inrush from the imager firing and the radio transmitting simultaneously pulls the cell voltage down momentarily. If the cell is already depleted or a degraded pack can't sustain the load, the radio drops out first — the scanner appears to read the barcode but the transmission never reaches the host. Run the scanner at above 30% charge during high-frequency scan sessions to keep the voltage above the radio's minimum operating threshold of approximately 3.4V.
