Point Mobile PM80 Replacement Battery 80-BTEC 3.85V 5000mAh

Point Mobile PM80 — 3.85V Li-Polymer Replacement Battery (80-BTEC)

This is a 3.85V, 5000mAh Li-Polymer battery for the Point Mobile PM80 handheld barcode scanner. It replaces OEM part numbers 80-BTEC and 80-BTSC. The PM80 is a mobile data collection device used across retail, warehousing, and logistics environments.

• PM80 platform fit: The PM80 uses a slim Li-Polymer pack with a specific BMS handshake tied to the device's power management IC. Both OEM references (80-BTEC and 80-BTSC) draw from the same voltage rail and connector spec, so this replacement covers either variant without modification.
• Bench tested on actual hardware: We ran this pack through scan-trigger cycling and wireless polling loads simultaneously. The BMS held steady through combined inrush events without false low-voltage cutoffs, and charge acceptance from the cradle was consistent across multiple cycles.
• First-shift preparation: After installing, seat the scanner in its cradle and let it complete a full charge cycle before starting a pick-and-pack shift. Scan trigger inrush is highest when the cell is near minimum — a fully charged pack prevents false BMS trips during the first hour of heavy use.

Cradle showing a charging error on a new pack

Charging docks on the PM80 read pack status through pogo-pin contacts on the battery base. If those contacts carry even light oxidation or manufacturing residue, the dock reports a fault before current flows. Wipe the battery contact pads and the cradle pins with a dry cloth, then reseat the pack firmly until it clicks. The dock should begin charging within 10 seconds of a clean, seated connection.

Scanner losing wireless connection during rapid scan bursts

On the PM80, the wireless radio and the scan imager draw from the same cell simultaneously during a fast scan burst. If the battery is partially discharged, combined inrush can pull cell voltage below the BMS communication threshold momentarily, dropping the wireless link. This is not a radio fault — it is a voltage sag event. Keeping the pack above 3.6V per cell eliminates this; top up the battery mid-shift if connection drops are appearing late in the day.
