Chameleon RF FL3500 Barcode Scanner Replacement Battery DT-5023BAT 3.7V 1800mAh Li-ion

Chameleon RF FL3500 / RF PB1900 / RF PB2100 — 3.7V Li-ion Replacement Battery (DT-5023BAT)

This 3.7V 1800mAh lithium-ion battery replaces the OEM pack in the Chameleon RF FL3500, RF PB1900, and RF PB2100 handheld barcode scanners. It matches the original voltage rail, capacity, and form factor exactly. Alternate OEM references DT-5024LBAT and CA50601-1000 cross directly to this pack.

• RF FL3500, PB1900, and PB2100 platform fit: All three scanners share the same battery bay dimensions, 3.7V nominal rail, and BMS communication protocol — one pack covers all three without modification or adapter.
• Bench tested on actual hardware: We cycled this pack through repeated scan bursts and wireless polling events. The BMS held steady through combined radio and trigger inrush without tripping the low-voltage cutoff or flagging a charge fault on the cradle.
• First-shift preparation for pick-and-pack use: After installing, seat the scanner in its cradle and run a full charge cycle before pulling it onto the floor. Scan trigger inrush current peaks when the cell is near minimum state of charge — a pre-charged cell stops false BMS trips at the start of the first shift.

Cradle showing a charging error on a new pack

Charging docks on the RF FL3500 series read the pack through spring-loaded contact pins. If those pins or the battery terminals carry any oxidation or factory residue, contact resistance climbs and the dock interprets the voltage drop as a fault condition. Remove the battery, wipe the gold contacts on both the pack and the cradle slot with a dry lint-free cloth, then reseat firmly. The dock should clear the error and begin a normal charge cycle within 30 seconds of correct contact.

Scanner dropping its wireless connection mid-scan burst

During a rapid scan sequence the scanner fires the imager, processes the decode, and transmits over the wireless link almost simultaneously. That combined draw — decode engine plus radio transmit — creates a short inrush spike. If the cell voltage sags too far under that spike, the radio module resets to protect itself, and the host system logs a dropped connection. This usually surfaces when the pack is below 30% charge. Keep the pack above that threshold during high-frequency scanning shifts and the connection stays stable.
