PSC 2M Barcode Scanner Replacement Battery 3.6V 1800mAh

PSC 2M / Falcon Top Gun 310 Series — 3.6V Ni-MH Replacement Battery (00-864-00)

This is a 3.6V, 1800mAh Ni-MH replacement battery for PSC handheld barcode scanners. It fits the 2M, 4M, Falcon Top Gun 310, Falcon Top Gun 315, and additional models in that family. OEM part numbers 00-864-00, 990004-0002, and 00-862-00 all cross to this pack.

• Multi-model fit across the PSC scanner family: The 2M, 4M, and Falcon Top Gun 310/315 all share the same 3.6V single-cell Ni-MH architecture and physical pack dimensions — 51.14 × 42.45 × 14.38mm — so one battery covers the group without adapter changes or connector modification.
• Bench tested on actual hardware: We cycled this pack through scan trigger inrush and wireless polling loads simultaneously. The BMS held stable across the combined draw and did not trip during burst-scan sequences at low state of charge.
• First-shift charging on Ni-MH scanner packs: Before using on the warehouse floor, seat the scanner in its cradle and run a full charge cycle. Ni-MH cells at low initial charge face the highest inrush current when the scan trigger fires — a fully charged pack prevents false BMS trips during the first pick-and-pack shift.

Cradle charging error on a new PSC pack

PSC cradle docks read pack state through pogo-pin contacts. A new pack sitting in a warehouse bag accumulates oxidation on those contacts fast enough to cause a dock handshake failure on the first seat. The dock interprets high contact resistance as a fault and throws a charging error rather than starting the charge cycle. Wipe the gold contacts on both the pack and the cradle with a dry cloth, reseat firmly, and the error clears in most cases without any dock reset.

Scanner drops wireless connection during rapid scan bursts

Rapid scanning combines two simultaneous current draws — the laser or imager and the wireless radio transmitting each decoded result. On a Ni-MH cell below roughly 3.2V, that combined inrush pulls the terminal voltage low enough to brown out the radio module before the BMS cuts the pack entirely. The scanner stays powered but loses its wireless link mid-shift, often with no warning light. Charge the pack fully before the shift starts and monitor for this symptom appearing in the last hour of use — that window indicates the cell is ready for replacement.
