Phaser P360 Barcode Scanner Replacement Battery 3.7V 1500mAh

Phaser P360 / P370 / P460 / P470 — 3.7V Li-ion Replacement Battery

This 3.7V, 1500mAh Li-ion cell replaces the factory battery in the Phaser P360, P370, P460, and P470 handheld barcode scanners. These are compact mobile data terminals used in warehouse, retail, and inventory environments. Same voltage, same chemistry, same form factor as the original.

• P360 / P370 / P460 / P470 platform fit: These four models share a common battery bay and connector spec. The BMS handshake is identical across the range, so one cell covers all four units without modification.
• Bench tested on actual hardware: We ran this pack through charge and discharge cycles on a P360 unit. The BMS accepted the cell immediately, protection circuits triggered correctly at threshold, and the scanner powered through both scan-trigger and wireless radio draw without fault.
• First-shift inrush protection: After installing a fresh cell, seat the scanner in its cradle and run a full charge cycle before pulling it onto the floor. Scan-trigger inrush current peaks highest when the cell is near minimum — a pre-charged pack prevents false BMS trips during the first pick-and-pack shift.

Cradle showing a charging error on a new pack

Charging docks on the P360 series read the pack through spring-loaded contact pins. If those pins are dirty or the pack isn't fully seated, the dock throws a charge fault even though the battery itself is fine. Wipe the gold contacts on both the pack and the cradle with a dry cloth, then reseat the scanner firmly until it clicks. If the fault clears, the issue was contact resistance — not a defective cell. A healthy dock will show a steady charge indicator within 30 seconds of a clean reseat.

Scanner dropping wireless connection during rapid scan bursts

During a fast scan sequence, the imager and the wireless radio draw current simultaneously. On a cell that's below roughly 3.5V, this combined inrush can cause a momentary voltage sag that drops the radio connection. The scanner may appear functional — screen on, trigger responding — but the wireless link drops until the cell recovers. Charge the pack to full before a high-volume shift, and if the drops persist mid-shift, check that the battery contacts are clean and making firm connection inside the bay.
