TSL 1062 HF Snap-On Reader 3.7V 1800mAh Replacement Battery

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

This is a 3.7V, 1800mAh Li-ion battery for the TSL 1062 HF Snap-On Reader and related TSL RFID reader platforms including the 1128, 1128 UHF RFID Reader, and 1153 Wearable RFID Reader. It replaces OEM part number 1128-00-BA-2000. The cell dimensions are 64.94 × 36.80 × 11.80mm — check these against your existing pack before ordering if you are unsure of the variant.

• TSL 1062, 1128, and 1153 platform fit: These TSL readers share a common battery form factor and BMS handshake protocol across the snap-on reader and wearable RFID lines. The same 3.7V cell and connector configuration services all models listed, which is why one SKU covers the full range.
• Bench tested on actual hardware: We ran this pack through charge and discharge cycles on TSL reader hardware. The BMS accepted charge without fault codes, and the protection circuit responded correctly to overvoltage and undervoltage thresholds during stress testing.
• First-shift charging for RFID scan inrush: After installing this pack, seat the reader in its charging cradle for a full charge cycle before running it on the warehouse floor. The RFID interrogation pulse combined with wireless polling draws peak current at the start of each scan burst — a cell near minimum charge is most likely to trigger the BMS cutoff on the very first shift.

Cradle showing a charging error on a new pack

TSL charging cradles read the battery's state through dock contacts on the base of the reader. If those contacts have oxidation, dust, or residue from a failed cell, the cradle may throw a charging fault even though the new pack is fine. The cradle interprets high contact resistance as a pack fault rather than a physical connection issue. Wipe the gold contacts on both the battery pack and the cradle dock with a dry cloth, reseat the reader firmly, and confirm the charging indicator activates within 30 seconds.

Scanner losing wireless connection during rapid scan bursts

During a rapid scanning sequence, the TSL reader fires the RFID interrogator and maintains a Bluetooth or Wi-Fi polling interval simultaneously. This combined inrush can briefly sag the cell voltage below the BMS hold threshold, causing the radio stack to drop. This is most common when the battery is below 20% charge. If wireless dropouts occur mid-shift, check the battery indicator — if it reads low, swap or recharge rather than continuing; the dropouts will worsen as cell voltage continues to fall toward the 3.0V cutoff floor.
