Symbol PTC-910 Barcode Scanner Replacement Battery 6V 900mAh

Symbol PTC-910 Series — 6V Ni-MH Replacement Battery (17289-000)

This 6V 900mAh Ni-MH pack replaces the original battery in the Symbol PTC-910, PTC910C, and PTC-910L handheld barcode scanners. These mobile data terminals are used in retail and warehouse inventory workflows, where the scanner reads barcodes and pushes data wirelessly. Voltage and cell count match the OEM spec exactly, so the pack seats and communicates correctly in both the scanner and its charging cradle.

• PTC-910, PTC910C, and PTC-910L compatibility: All three models run the same 6V power rail and share the same connector and BMS handshake profile. A single pack covers the full lineup — no wiring changes, no adapter needed.
• Bench tested on actual hardware: We cycled this pack through the PTC-910 and monitored BMS response during back-to-back scan trigger events combined with active wireless polling. The protection circuit held within spec and did not trip during sustained burst scanning.
• First-shift cradle protocol: After installing a fresh pack, seat the scanner in its cradle and allow a complete charge cycle before starting pick-and-pack operations. Scan trigger inrush current peaks when the cell is near minimum charge — a full cell going into the first shift prevents false BMS trips during the earliest high-demand scans.

Cradle showing a charging error on a new pack

Ni-MH packs shipped in a storage state can confuse the cradle's charge controller on the first insertion — the dock reads low cell voltage and flags it as a fault rather than initiating a trickle-start charge. The fix is usually contact-related: oxidation or debris on the pack's charging contacts causes resistance that the cradle interprets as an open circuit. Wipe the contacts on both the pack and the cradle slot with a dry cloth, reseat the pack firmly, and wait 30 seconds for the controller to re-poll. If the error clears, the charge cycle will begin normally at the trickle rate before stepping up.

Scanner dropping wireless connection during rapid scan bursts

The PTC-910 draws from the same cell for both the scan trigger and the wireless radio simultaneously. During a fast burst — continuous scanning across multiple barcodes — the combined inrush causes a momentary voltage dip that the radio interprets as a low-power disconnect event. This is more pronounced on an aged or deeply discharged pack, where internal resistance amplifies the sag. Running this pack at or above 6.0V under load keeps the combined draw within the radio module's operating threshold and prevents mid-burst dropouts.
