About this replacement
Opticon OPL-9714 / OPL-9815 Series — 3.7V Li-ion Replacement Battery (N10-1000MA)
This is a 3.7V, 1000mAh Li-ion replacement battery for the Opticon OPL-9714 barcode scanner and related models. It fits the OPL-9715, OPL-9815, and OPL-9727 alongside additional compatible units in the same family. Capacity figures come directly from product data — 3.7Wh, matching the original specification.
- OPL-9714 / OPL-9815 family fit: These models share the same 3.7V power rail, physical cell footprint (53.17 × 35.35 × 6.84mm), and connector pinout. The BMS handshake is consistent across the range, so one cell covers the full group without adapter or modification.
- Bench tested on actual hardware: We cycled this pack through scan-trigger and wireless polling loads simultaneously. The BMS held charge acceptance cleanly across repeated inrush events without tripping into protection mode.
- First-shift charging protocol: After installing, seat the scanner in its cradle and run a full charge cycle before picking up any scan work. Scan trigger inrush is highest when the cell is near minimum voltage — a fully charged pack prevents false BMS trips on your first shift.
Cradle showing a charging error on a new pack
Most cradle charging errors after a battery swap come down to contact resistance between the dock pins and the battery terminals, not a fault in the cell itself. Oxidation or debris on the gold-plated contacts is enough to push resistance above the threshold the dock uses to confirm a valid pack. Wipe the battery contacts and dock pins with a dry lint-free cloth, then reseat the scanner with firm, even pressure. If the error clears within 30 seconds of reseating, contact resistance was the cause — not the battery.
Scanner losing wireless connection during rapid scan bursts
During a fast scan burst, the imager and the wireless radio draw current at the same time, creating a combined inrush spike the BMS must absorb simultaneously. If the cell voltage dips below roughly 3.2V under that combined load, the BMS may briefly throttle output to protect the cell — the radio drops first because it is the lower-priority draw. Let the battery charge to full before a high-volume pick shift. If dropouts continue on a fully charged pack, check that the scanner firmware has not flagged the cell as low-capacity, which some Opticon models do after detecting multiple partial cycles.
