Telxon TSC1 Data Collector 7.4V Li-ion Replacement Battery

Telxon TSC1 Data Collector — 7.4V Li-ion Replacement Battery

This 7.4V Li-ion cell delivers 2000mAh (14.8Wh) to the Telxon TSC1 handheld data collector. The TSC1 is a field-deployed mobile computer used for logistics scanning, retail inventory, and enterprise data capture. When the original pack degrades and causes shutdowns or false low-battery warnings mid-session, this is the direct swap.

• TSC1 platform compatibility: The TSC1 uses a fixed 7.4V two-cell Li-ion architecture. The battery connector and BMS handshake are matched to this voltage rail — swapping to a mismatched pack causes the device to refuse to boot or report a battery fault immediately on insertion.
• Bench tested on actual hardware: We cycled this pack through the TSC1's charge controller and monitored BMS response during simulated probe-initialisation current spikes. The protection circuit held within spec and did not trip under the load transient the TSC1 generates at startup.
• First-deployment calibration: After fitting this pack, run a full calibration cycle through the TSC1 instrument menu before heading into the field. The device maps battery state during calibration — skipping this step causes premature low-battery warnings to appear during your first logging session even when the pack is well charged.

TSC1 shutting down mid-scan when sensor or barcode module initialises

When the TSC1 powers its scan module, there is a brief but sharp current draw — often 400–600mA above idle. An aged original battery with elevated internal resistance cannot sustain the voltage rail through that spike. The cell voltage dips below the BMS cutoff threshold and the device shuts off, even if the battery indicator showed a reasonable charge beforehand. A fresh pack with lower internal resistance holds the rail steady through the transient, and the shutdown stops.

TSC1 powers on but cuts out during USB data transfer to PC

USB data transfer on the TSC1 combines active CPU load, memory bus activity, and the USB port's own draw simultaneously. This sustained combined load pulls more current than most single operations and can drop a weakened pack below 6.8V — the point where the BMS disconnects to protect the cells. If the device only cuts out during transfer and not during scanning alone, the pack is the cause, not the USB driver or host PC. Fit the replacement, confirm charge is above 7.2V at rest, then retry the transfer.
