CipherLab 8200 Barcode Scanner Replacement Battery 3.7V 1100mAh

CipherLab 8200 / CPT-8300 Series — 3.7V Li-ion Replacement Battery (KB1B371200005)

This 3.7V, 1100mAh Li-ion battery replaces the original pack in the CipherLab 8200, CPT-8300, 8300, and 8000 series handheld barcode scanners. These are portable data collection devices used in retail, warehouse, and logistics environments for inventory scanning and point-of-sale transactions. It also carries OEM reference BA-80S1A2.

• 8200 / 8300 / 8000 platform fit: These models share the same battery bay geometry, connector pinout, and BMS handshake protocol — one cell SKU covers the full family. The scanner's host firmware communicates with the pack's protection circuit to verify voltage thresholds before enabling the scan trigger.
• Bench tested on actual hardware: We cycled this pack through repeated scan-trigger inrush events and monitored the BMS cutoff response. The protection circuit held stable at the expected low-voltage floor without nuisance trips during burst scanning.
• First-shift preparation on the CipherLab cradle: After installing, seat the scanner in its charging cradle and let it complete 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 prevents false BMS trips that would otherwise halt scanning mid-shift.

Cradle showing charging error on a freshly installed pack

Charging docks on the 8200 series use spring-loaded contacts that corrode or collect debris over time. A new pack with slightly higher contact resistance than the worn original can push the dock's charge controller outside its expected impedance window, triggering an error flag. Wipe the gold contacts on both the battery and the cradle with a dry cloth, then firmly reseat the scanner. If the error clears, the pack is fine — the dock contacts were the cause.

Scanner losing wireless connection during rapid scan bursts

During a rapid scan burst, the 8200's radio and scan trigger fire simultaneously, creating a combined inrush spike that momentarily sags cell voltage. If the pack's state of charge is already low, that sag can cross the BMS undervoltage threshold, causing the scanner to drop its wireless link before the trigger even completes. The fix is to avoid running the pack below the point where the status LED first signals low battery — return it to the cradle at that point rather than continuing the scan run. A rested, charged pack handles the combined radio-plus-trigger load without the voltage sag.
