Point Mobile PM70 Barcode Scanner Compatible Battery 3.8V 2900mAh

Point Mobile PM70 — 3.8V Li-ion Replacement Battery (70-BTSC)

This 3.8V, 2900mAh Li-ion battery replaces the OEM pack in the Point Mobile PM70 handheld barcode scanner. It fits the PM70 directly using the original battery bay and connector. Voltage and capacity match the factory spec — 3.8V, 2900mAh (11.02Wh).

• PM70 platform fit: The PM70 uses a slim single-cell Li-ion pack with a locked voltage rail at 3.8V nominal. The BMS handshake on this device checks cell impedance at startup — a cell outside spec triggers a boot fault before the OS loads. This replacement pack meets that impedance window.
• Bench tested on actual hardware: We cycled this pack through simulated scan-burst sequences and monitored BMS cutoff behaviour under combined laser and wireless radio draw. The cell held voltage above the BMS low-threshold floor across repeated trigger pulls without tripping an early cutoff.
• First-shift cradle protocol: After installing, seat the scanner in its charging cradle and run a full charge cycle before the first pick-and-pack shift. Scan trigger inrush current peaks when the cell is near minimum — a fully charged cell on first use prevents a false BMS trip during heavy early-shift scanning.

Cradle showing a charging error on a new PM70 battery pack

The PM70 cradle reads the battery through spring-loaded dock contacts on the base of the unit. If those contacts have oxidation or debris from warehouse handling, the cradle sees high contact resistance and throws a charging fault rather than starting the charge cycle. This is not a faulty pack — it is a contact issue. Wipe the gold contacts on both the battery and the cradle dock with a dry lint-free cloth, then reseat the scanner firmly. The fault clears once contact resistance drops below the cradle's threshold and the charge handshake completes.

PM70 losing wireless connection during rapid scan bursts

During fast barcode scanning, the PM70 draws current simultaneously from the scan engine and the wireless radio — both firing in short, overlapping bursts. On a degraded or deeply discharged cell, this combined inrush pulls the voltage low enough that the radio drops its connection to maintain power to the scan engine. The result looks like a network fault but the root cause is voltage sag at the cell. Charge the replacement pack fully before use and confirm cell voltage reads at or above 3.8V before starting a high-volume scanning shift.
