68-BTSC Point Mobile PM86 Scanner Replacement Battery 3.8V 4000mAh

Point Mobile PM86 — 3.8V Li-ion Replacement Battery (68-BTSC)

This is a 3.8V, 4000mAh Li-ion replacement battery for the Point Mobile PM86 handheld barcode scanner. It matches the OEM part number 68-BTSC and fits the PM86 used in retail, logistics, and warehouse environments. Voltage and capacity are spec-matched to the original pack.

• PM86 platform fit: The PM86 uses a dedicated battery bay with a BMS handshake tied to the 3.8V cell voltage rail. This replacement carries the same nominal voltage and cell configuration, so the scanner's power management firmware recognises the pack and allows normal boot and scanning operation.
• Bench tested on actual hardware: We ran this pack through the PM86's power-on sequence and monitored the BMS for cutoff events during scan trigger inrush and simultaneous wireless polling. The cell held voltage within the acceptable window across both draw events with no spurious shutdowns recorded.
• First-shift preparation for pick-and-pack use: Place the scanner in its cradle for a full charge cycle before the first shift. Scan trigger inrush current is highest when the cell is near minimum, and a fully charged pack prevents false BMS trips during the first heavy scanning run of the day.

Cradle showing a charging error after fitting a new pack

Charging docks on the PM86 use spring-loaded contact pins that can accumulate oxidation or debris over time. A new battery with clean contacts hitting a contaminated dock will show a charging fault even though neither the dock nor the pack is actually faulty. The dock's charge controller reads contact resistance above its threshold and flags an error rather than starting a charge cycle. Wipe the battery contacts and the dock pins with a dry cloth, reseat the scanner firmly, and the error clears in most cases.

Scanner dropping wireless connection during rapid back-to-back scanning

The PM86 draws current from two sources simultaneously during a rapid scan burst — the imager and the wireless radio. When the cell voltage dips under combined load, the radio subsystem can lose enough power to drop its connection to the access point before the BMS trips the battery entirely. This is more likely with a degraded original pack but can also occur on a new cell if the device is coming off a partially depleted charge. Charge the pack to full before a high-frequency scanning shift and the combined inrush stays within the cell's delivery window.
