IEIMobile MODAT-200 Compatible Battery 3.7V 1800mAh

IEIMobile MODAT-200 — 3.7V Li-Polymer Replacement Battery (1ICP4/54/85)

This 3.7V 1800mAh lithium-polymer battery replaces the OEM pack in the IEIMobile MODAT-200 handheld barcode scanner. It matches the original cell format at 86.57 × 49.85 × 3.80mm and slots into the existing battery bay without modification. Voltage and capacity are sourced from the OEM specification — 1800mAh, 6.66Wh.

• MODAT-200 platform fit: The MODAT-200 uses a slim Li-Polymer cell with a fixed connector pinout that carries both power and BMS communication to the device. The 1ICP4/54/85 format is specific to this scanner chassis — a mismatched cell thickness will prevent the battery door from seating and break the BMS data line.
• Bench tested on actual hardware: We cycled this pack through repeated scan-trigger bursts while monitoring the BMS cutoff thresholds. The protection circuit held within spec during back-to-back high-frequency scan events, and cell voltage recovery between bursts stayed consistent across the test run.
• First-shift preparation: After installing, place the MODAT-200 in its cradle for a full charge cycle before pulling triggers on the first shift. Scan trigger inrush current peaks when the cell is near minimum charge — starting the shift on a full cell prevents false BMS trips that can misread as a hardware fault.

Cradle showing charging error on a new MODAT-200 pack

The MODAT-200 cradle communicates with the battery BMS through spring-loaded dock contacts. If those contacts are oxidised or have residue from the old pack, the cradle cannot read the new cell's charge state and throws a fault. This is a contact resistance issue, not a faulty battery. Wipe the gold contacts on both the pack and the cradle with a dry lint-free cloth, reseat the scanner firmly, and the charge indicator should clear within 30 seconds.

Scanner losing wireless connection during rapid scan bursts

During a fast scan sequence, the MODAT-200 draws simultaneously from the imager and the wireless radio — two inrush loads hitting the cell at the same time. If the cell voltage sags below the radio module's minimum operating threshold during that combined draw, the wireless stack drops and needs to re-associate with the access point. This appears as a connection dropout rather than a scan failure, so it is often misdiagnosed as a network issue. Charge the pack fully before high-frequency scanning shifts — a cell starting above 3.9V handles the combined load without voltage sag severe enough to drop the radio.
