Zebra DS3600 Replacement Battery 3.7V 2200mAh BTRY-36IAB0E-00

Zebra DS3600 / DS3678 Series — 3.7V Li-ion Replacement Battery (BTRY-36IAB0E-00)

This 3.7V, 2200mAh Li-ion battery replaces the OEM pack in the Zebra DS3600 and DS3678 handheld barcode scanners, along with the LI3600 and EVM series. It matches the original cell format, connector, and BMS communication protocol. Capacity is rated at 8.14Wh, consistent with the factory spec.

• DS3600 and DS3678 platform fit: These models share the same battery bay geometry, contact pin arrangement, and BMS handshake protocol. One pack covers the full scanner family without adapter or modification.
• Bench tested on actual hardware: We ran this pack in a DS3678 cradle and across scan trigger cycles. The BMS held charge acceptance within spec and showed no false low-voltage trips during simulated burst scanning with active Bluetooth.
• 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 into a pick-and-pack shift. Scan trigger inrush current peaks when the cell is near minimum charge — a pre-charged pack prevents false BMS cutoff on the first heavy burst of the day.

Cradle showing a charging error on a new pack

A charging fault on a new battery is almost always a contact issue, not a pack failure. The DS3600 cradle uses gold-plated pogo pins that pick up oxidation and debris from warehouse floors quickly. Dirty contacts raise resistance enough that the cradle's charge controller reads an open circuit or over-temperature condition and throws an error. Remove the pack, wipe both the battery contacts and cradle pins with a dry lint-free cloth, then reseat firmly until you hear the latch click.

Scanner dropping wireless connection during rapid scan bursts

During a fast scan burst, the imager and Bluetooth radio draw current simultaneously — a combined inrush the BMS can briefly flag as an overload if the cell voltage is already low. When the BMS trips, the radio drops its connection before the imager cuts out, so the scanner appears to scan but data stops transmitting. This is not a radio fault. Charge the pack to full before the shift and monitor for the same drop — if it recurs only below roughly 3.5V under load, the cell is reaching end-of-life and the pack needs replacement.
