Vokkero GUARD CHX1 Barcode Scanner Replacement Battery BAT-010 3.7V

Vokkero GUARD CHX1 / FCE Series — 3.7V Li-ion Replacement Battery (BAT-010)

This is a 3.7V, 1800mAh Li-ion battery for the Vokkero GUARD CHX1 and GUARD FCE-series handheld barcode scanners. It replaces OEM part numbers BAT-010 and BAT-020. The pack fits the GUARD FCE001-ST, FCE02, and FCE03 alongside the CHX1 — all share the same voltage rail and form factor.

• GUARD CHX1 and FCE-series compatibility: These models run off the same 3.7V single-cell architecture with a shared connector and BMS handshake protocol. One pack covers the whole family — no firmware or voltage mismatch to worry about across the range.
• Bench tested on actual hardware: We cycled this pack through repeated scan-burst sequences on the CHX1 platform and monitored BMS response during combined wireless polling and trigger inrush. The protection circuit held stable cutoffs at both ends of the charge window throughout testing.
• First-shift preparation on the CHX1: After fitting the new pack, seat the scanner in its cradle and run a full charge cycle before starting pick-and-pack. Scan trigger inrush current peaks when the cell is near minimum. A fully charged cell prevents false BMS trips on the first shift's opening scans.

Cradle showing a charging error on a new BAT-010 pack

Charging errors on a fresh pack are almost always a dock contact problem, not a faulty battery. The CHX1 cradle uses spring-loaded pogo pins that collect dust and label residue in warehouse environments. Oxidation or debris raises contact resistance high enough that the dock's charge controller reads a fault instead of initiating a charge cycle. Wipe the battery contacts and cradle pins with a dry cloth, reseat the scanner firmly, and the charge indicator should clear within 30 seconds.

Scanner losing wireless connection during rapid scan bursts

The CHX1 draws current simultaneously from its wireless radio and the scan trigger during a rapid burst sequence. When the cell voltage dips under combined load, the radio module drops its connection before the BMS trips — the scanner goes dark on the network while the display stays on. This is a voltage-sag symptom, not a radio fault. A cell holding its charge correctly keeps voltage above the radio's minimum threshold of approximately 3.2V under combined draw. If the disconnect persists on a charged pack, check that the battery contacts are clean and making full surface contact with the scanner's terminals.
