Casio CA60L1-G DT-5300 Barcode Scanner Battery 3.7V 3600mAh

Casio DT-5300 / IT-600 Series — 3.7V Li-ion Replacement Battery (CA60L1-G)

This 3.7V, 3600mAh Li-ion battery replaces the CA60L1-G and related OEM packs in the Casio DT-5300, IT-300, IT-600, and IT-800 barcode scanners. These are handheld data collection devices used in retail, warehousing, and logistics. It fits the same physical bay, connector, and BMS communication protocol as the original Casio pack.

• DT-5300 / IT-Series platform fit: The DT-5300, IT-300, IT-600, and IT-800 share the same 3.7V battery bay and BMS handshake. One cell format covers all four scanners without adapter or firmware change.
• Bench tested on actual hardware: We ran this pack through charge and discharge cycles on compatible hardware. The BMS accepted the pack without error flags, balanced the cells correctly, and reported accurate state-of-charge to the device.
• First-shift preparation: After installing, seat the scanner in its charging cradle and run a full charge cycle before the first pick-and-pack shift. Scan trigger inrush current is highest when the cell is near minimum voltage — a fully charged pack prevents false BMS trips on the first draw of the day.

Cradle showing charging error on a new pack

Charging errors on a fresh pack are almost always a contact resistance problem, not a fault with the cell. The cradle's charge pins read pack voltage through the battery contacts — any oxidation or debris on either surface raises resistance enough to trigger an error flag. Wipe the gold contacts on the battery and the cradle pins with a dry cloth, reseat the pack firmly, and the error clears in most cases. If the error persists after reseating, check that the cradle firmware recognises the pack voltage at 3.7V nominal.

Scanner losing wireless connection during rapid scan bursts

During a rapid scan burst, the scanner is pulling current from two sources simultaneously — the imager or laser module and the wireless radio. That combined inrush can cause a brief voltage sag on a cell that is below 50% charge. When the sag crosses the BMS low-voltage threshold, the radio drops out first because the scanner's power management prioritises the scan engine. The fix is to keep the pack above half charge during high-frequency scanning shifts. If dropouts persist on a fully charged pack, check the battery contacts for debris causing extra resistance under load.
