About this replacement
Honeywell Dolphin CT60 / CT50 Series — 3.8V Li-Polymer Replacement Battery (CT50-BSC-B)
This is a 3.8V, 4700mAh Li-Polymer battery for the Honeywell Dolphin CT60, CT65, and CT50 mobile computers. These rugged handhelds are used in retail, warehousing, and logistics for barcode scanning and inventory data collection. One battery covers the CT50 and CT60 family — the voltage rail, connector pinout, and BMS handshake are identical across these models.
- CT50 and CT60 platform compatibility: Honeywell carried the same battery architecture from the CT50 through to the CT65 — same 3.8V nominal voltage, same physical form factor, and the same four-pin BMS communication interface. A single battery slot fits the full series without modification.
- Bench tested on actual hardware: We cycled this pack on a CT60 unit under combined scan-trigger and Wi-Fi polling load. The BMS held voltage above the 3.2V low-cell threshold throughout discharge and balanced all cells within 20mV on termination.
- First-shift preparation for pick-and-pack use: Before deploying on a busy shift, seat the scanner in its cradle and let it complete a full charge cycle. Scan-trigger inrush current peaks when the cell is near minimum — a fully charged pack prevents false BMS cutoff trips during the first hour of use.
Cradle showing a charging error on a new pack
Honeywell CT-series cradles read battery state through the dock's spring contacts before initiating a charge cycle. If those contacts have oxidation or debris from warehouse handling, the dock can misread the pack's BMS signal and throw a charging fault. Remove the battery, wipe the gold contacts on both the pack and the cradle bay with a dry lint-free cloth, then reseat firmly. If the error clears, the contacts were the cause — not the battery itself.
Scanner dropping Wi-Fi mid-shift during rapid scan bursts
The CT60 runs its 802.11 radio and imager from the same cell simultaneously. During rapid scan bursts — tight pick-and-pack cycles with back-to-back triggers — the combined inrush can cause a momentary voltage sag on an aged or partially charged cell. The radio stack interprets that sag as a brownout and drops the access point association. This is not a software or network issue — it is a battery voltage floor problem. Charge the replacement pack fully before the shift and the sag stays within the radio's tolerance band.
