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

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

This is a 6V 900mAh Ni-MH battery for the Telxon PTC-910, PTC-910C, and PTC-910L handheld barcode scanners. These units are common in retail, warehousing, and logistics pick operations where consistent scan performance matters. The OEM part numbers 17289-000 and 17289-001 both cross to this pack.

• PTC-910, PTC-910C, and PTC-910L coverage: All three variants run the same 6V power rail and use the same battery connector and housing slot, so one pack covers the full lineup without any modification.
• Bench tested on actual hardware: We cycled this pack through the scanner's BMS under combined laser trigger and radio polling loads. The BMS held stable across repeated burst sequences and did not trip on inrush during rapid consecutive scans.
• First-shift preparation for pick-and-pack use: Before the first shift, seat the scanner in its charging cradle and run a full charge cycle. Scan trigger inrush is highest when the cell is near minimum charge, and a fully charged pack prevents false BMS trips during the first heavy scan burst of the day.

Cradle showing a charging error on a new pack

A charging error on a fresh pack is almost always a contact resistance problem, not a fault with the battery itself. The cradle pins and the battery contact pads oxidise over time, and a new pack with clean contacts can still fail to handshake if the cradle side is dirty. Wipe the gold contact pads on the battery with a dry cloth, then wipe the cradle pins with a lint-free swab. Reseat the scanner firmly and confirm the charge indicator activates within 10 seconds.

Scanner losing wireless connection during rapid scan bursts

The PTC-910 draws simultaneously from the radio transceiver and the scan trigger during a rapid burst sequence. On a degraded or deeply discharged cell, this combined inrush pulls voltage below the radio module's minimum operating threshold, dropping the wireless link. The scanner may reconnect seconds later, which looks like an intermittent RF issue rather than a power issue. Charge the pack fully before the shift and confirm resting voltage reads at or above 6.0V before deploying the unit.
