About this replacement
Unitech PA960 Series — 7.4V Li-ion Replacement Battery (1400-202017)
This 7.4V 1850mAh Li-ion battery replaces the original pack in the Unitech PA960, PA962, PA963, and RH767 handheld barcode scanners. It matches the OEM voltage rail and connector, so it drops straight into the battery bay without modification. Capacity is rated at 1850mAh (13.69Wh) — the same as the factory specification.
- PA960 / PA962 / PA963 / RH767 compatibility: These four models share the same 7.4V battery bay, connector pinout, and BMS handshake protocol — the same cell pack fits all of them without an adapter or firmware change.
- Bench tested on actual hardware: We cycled this pack through scan-trigger inrush events on the PA960 platform. The BMS held voltage above the low-cell threshold during rapid burst scanning combined with active 802.11 wireless polling — no premature cutoff observed.
- First-shift preparation: After installing this pack, seat the scanner in its cradle and complete a full charge cycle before running a picking shift. Scan-trigger inrush current peaks when the cell is near minimum, and a fully charged cell prevents a false BMS protection trip during the first hour of use.
Cradle showing a charging error on a brand-new pack
The PA960 charging cradle monitors contact resistance on the battery terminals. If resistance reads high — even briefly — the dock firmware flags a fault and stops the charge cycle. This happens most often with a new pack because the gold-plated contacts on the cell haven't seated fully yet. Wipe the battery contacts with a dry cloth, reseat the pack firmly, and confirm the cradle LED switches from fault amber to charge green within 10 seconds.
Scanner dropping wireless connection during rapid scan bursts
The PA960 draws current simultaneously from the laser or imager, the scan trigger, and the 802.11 radio — all three fire at near the same moment during a rapid burst. On a degraded or low-charge cell, that combined inrush pulls voltage below the radio module's minimum operating threshold, causing the wireless stack to reset. The scan engine stays active but the terminal link drops, so scans queue locally and sync is lost. Charge the battery to at least 7.2V before a high-frequency scanning shift to keep the voltage headroom above both the radio and imager minimums.
