TSL 1062 HF Snap-On Reader Compatible Battery 3.7V 900mAh

TSL 1062 HF Snap-On Reader — 3.7V Li-ion Replacement Battery (1128-00-BA-2000)

This is a 3.7V, 900mAh Li-ion replacement battery for the TSL 1062 HF Snap-On Reader and the TSL 1128 UHF RFID Reader family. It uses OEM part number 1128-00-BA-2000 and slots into the snap-on housing at the base of the handheld unit. Also fits the 1153 Wearable RFID Reader where the same pack format is used.

• 1062, 1128, and 1153 compatibility: These TSL readers share a common 3.7V cell format and snap-on mechanical interface. The BMS in each unit uses the same voltage thresholds and charge termination handshake, so one cell specification covers the full range of compatible readers without modification.
• Bench tested on actual hardware: We cycled this pack on the 1128 platform, running repeated scan-and-transmit bursts to stress the BMS under combined inrush from the imager and the UHF radio simultaneously. The protection circuit held cutoff at the correct low-voltage threshold throughout all discharge cycles.
• First-shift installation tip: After installing the new pack, seat the scanner in its charging cradle and let it complete a full charge cycle before using it on the pick floor. The scan trigger inrush current peaks when the cell is near minimum charge — a fully charged cell prevents a false BMS trip on the first high-frequency scan burst of the shift.

Cradle showing a charging error on a brand-new pack

TSL charging cradles use contact-based charge detection. If the gold pogo pins on the dock or the corresponding pads on the snap-on pack have oxidation or debris, the cradle reads an open circuit and flags a charge fault rather than beginning the charge cycle. This happens most often with new packs that have been stored before sale — the cell voltage may sit below the cradle's detection threshold. Wipe the pack contacts and cradle pins with a dry cloth, reseat the scanner firmly, and the charge indicator should switch to active within 30 seconds.

Scanner dropping its Bluetooth pairing mid-scan session

The 1062 and 1128 readers drive the UHF or HF radio and the imager simultaneously during active scanning. When the cell voltage sags below approximately 3.5V under this combined load, the radio module loses enough headroom to maintain its transmission window and the Bluetooth link drops before the BMS hits full cutoff. A cell that looks charged at rest may still sag under the combined radio-plus-imager draw if it has degraded. If pairing drops consistently during dense scan bursts, check resting voltage on the pack — anything below 3.6V at rest warrants a full charge before the next shift.
