Opticon 15101 Barcode Scanner Replacement Battery 3.7V 250mAh

Opticon OPN-2500 / 15101 — 3.7V Li-Polymer Replacement Battery (AHB582025)

This is a 3.7V, 250mAh Li-Polymer cell built to the AHB582025 specification. It fits the Opticon 15101 and OPN-2500 handheld barcode scanners. Physical dimensions are 26.90 × 19.70 × 6.00mm — confirm against the original cell before installing.

• OPN-2500 and 15101 platform fit: Both models share the same compact housing, connector pinout, and BMS handshake protocol — one cell covers both. The 3.7V nominal rail matches what the onboard scan engine and Bluetooth radio expect.
• Bench tested on actual hardware: We cycled this pack through repeated scan-trigger and wireless polling loads. The BMS held stable charge acceptance and did not trip during combined radio-plus-laser draw.
• First-shift cradle protocol: After installing, seat the scanner in its cradle for a complete charge cycle before pulling it into pick-and-pack work. Scan-trigger inrush current peaks when the cell is near minimum — a fully charged cell prevents false BMS trips on the first heavy shift.

Cradle showing a charging error on a new pack

Charging docks on the OPN-2500 read pack state through pogo-pin contacts. Oxidation or residue on those contacts raises resistance enough that the dock reports a fault rather than initiating a charge cycle. Wipe the contacts on both the scanner and the cradle with a dry cloth, then reseat the unit firmly. If the error clears, let the pack charge to 4.2V before use.

Scanner not reading barcodes immediately after battery swap

Replacement cells ship at a partial state of charge — often below the threshold the OPN-2500 scan engine needs to fire reliably. The laser or imager may activate but output falls short of what the decoder requires, producing missed reads or no read at all. Place the scanner in the cradle and charge fully before the first scan session. Once the cell reaches operating voltage, read performance returns to normal.
