Opticon H15 Barcode Scanner Compatible Battery 3.7V 1800mAh

Opticon H15 / H-15a / H-15b Series — 3.7V Li-ion Replacement Battery (02-BATLION-10)

This is a 3.7V, 1800mAh Li-ion battery for the Opticon H15 family of handheld mobile data terminals. It fits the H15, H-15a, H-15b, and H-15AJ variants used in retail, warehouse, and inventory scanning environments. Capacity figure is drawn directly from product data — 6.66Wh total.

• H15 family compatibility: The H15, H-15a, H-15b, and H-15AJ all share the same 3.7V battery bay, connector pinout, and BMS handshake protocol. OEM part numbers 02-BATLION-10, BTR0300, BTR0500, BP07-000120, and 11855 all reference this same cell configuration across different regional SKUs.
• Bench tested on actual hardware: We cycled this pack through scan-trigger inrush events and sustained wireless polling loads. The BMS held its cutoff thresholds at both ends of the charge curve — no false trips under combined radio and imager draw.
• First-shift preparation for pick-and-pack: After installing this pack, seat the scanner in its cradle and run a full charge cycle before the first shift. Scan trigger inrush current peaks when the cell voltage is near minimum — a fully charged cell prevents the BMS from tripping on the first burst of rapid scans.

Cradle showing a charging error on a new pack

A charging error on a new pack is almost always a contact resistance issue, not a battery fault. Dock contacts on high-use cradles build up oxidation and debris that interrupt the charge handshake. Remove the scanner, wipe the battery contacts and cradle terminals with a dry cloth, then reseat firmly. If the error clears, the cradle was reading the pack as absent rather than faulty.

Scanner not reading barcodes after a battery swap

The imager or laser in the H15 requires a stable voltage rail to fire correctly — if the replacement pack ships at a low state of charge, the scan trigger inrush can pull voltage below the imager's minimum operating threshold. The scanner appears to power on normally but the read fails or produces no beam. Place the unit in the cradle and charge to full before attempting reads. A fully charged cell should hold above 4.1V under scan trigger load.
