Datalogic PBT9500 Compatible Battery 3.7V 3350mAh RBP-9000

Datalogic PBT9500 / PM9500 Series — 3.7V Li-ion Replacement Battery (RBP-9000)

This 3.7V, 3350mAh Li-ion cell replaces the original pack in the Datalogic PBT9500, PM9100, PM9300, and PM9500 handheld barcode scanners. It matches the OEM connector, voltage rail, and BMS communication profile used across this scanner family. Capacity is rated at 3350mAh (12.4Wh) — same as the factory spec.

• PBT9500 and PM-series compatibility: These models share the same battery bay dimensions, 3.7V single-cell architecture, and BMS handshake protocol. The RBP-9000 footprint fits all four variants without modification to the housing or contacts.
• Bench tested on actual hardware: We ran this pack through charge and discharge cycles on a PBT9500 unit. The BMS negotiated correctly with the host device, balancing cut-in and cut-off thresholds without triggering a false low-battery shutdown during scan bursts.
• First-shift preparation for pick-and-pack use: After installing, seat the scanner in its cradle and run a full charge cycle before the shift starts. The scan trigger inrush current peaks when the cell is near minimum voltage — starting the first shift on a fully charged pack prevents BMS trips during rapid scanning sequences.

Cradle showing a charging error on a new pack

New packs sometimes ship with oxidation or light contamination on the contact pads from packaging. The cradle reads contact resistance above its handshake threshold and flags it as a charging fault rather than a cell fault. Wipe the gold contacts on the battery and the cradle dock with a dry lint-free cloth, then reseat the pack firmly. If the error clears, the cell is charging normally — the cradle will show a solid charge indicator within a few seconds of a clean connection.

Scanner dropping wireless connection during rapid scan bursts

The PBT9500 draws from the same cell simultaneously for the imager, the wireless radio, and the onboard processor. During rapid back-to-back scans, the combined inrush can cause a momentary voltage sag below the radio module's minimum operating threshold — the radio resets mid-burst and drops the connection. This is more common when the cell is below 30% charge. Keeping the pack above 3.6V under load eliminates most mid-shift disconnection events.
