Motorola 3 Model C Barcode Scanner Replacement Battery 3.7V 3300mAh

Motorola WorkAbout Pro 4 / 3 Model C Series — 3.7V Li-ion Replacement Battery

This 3.7V, 3300mAh lithium-ion battery fits the Motorola 3 Model C, 3 Model S, WorkAbout Pro 4, and WorkAbout Pro G1 handheld barcode scanners. These devices are used in retail, warehouse, and logistics environments where scanning uptime directly affects throughput. The pack ships at a partial state of charge — seat it in the cradle before your first shift.

• WorkAbout Pro and 3-Series platform fit: These models share a common battery bay geometry, contact pinout, and BMS communication protocol. One cell SKU covers the full range without modification or adapter.
• Bench tested on actual hardware: We cycled this pack through repeated scan-trigger and wireless polling loads on a WorkAbout Pro 4 unit. The BMS held voltage within spec across burst sequences and did not trip on simulated inrush at low state of charge.
• First-shift cradle charge: After installing, place the scanner in its cradle for a complete charge cycle before committing it to pick-and-pack. Scan trigger inrush current peaks when the cell is near minimum — a fully charged pack prevents false BMS cutoffs on the opening shift.

Cradle showing a charging error on a new pack

Charging docks on the WorkAbout Pro series read BMS status through the battery contacts before releasing charge current. If those contacts carry oxidation or shipping residue, the dock flags a fault and stops. Wipe the gold contacts on both the battery and cradle with a dry cloth, then reseat the pack firmly until the dock LED changes state. If the error persists after cleaning, the BMS may be in a low-voltage lockout — leave the pack seated for 15 minutes and let the dock attempt a recovery pulse.

Scanner dropping wireless connection during rapid scan bursts

A fast scan sequence draws current from the imager and the wireless radio at the same time. If the cell voltage sags below the radio module's operating threshold during that combined draw, the link drops — often just for a second, which looks like interference. This is more common late in a shift when the cell is partially depleted. Check the battery indicator before a high-volume task; if it reads below two bars, swap the pack and charge the low one rather than pushing through the burst session.
