About this replacement
Symbol MC9000S Short Terminal — 7.4V Li-ion Replacement Battery (21-62960-01)
This 7.4V 1550mAh Li-ion battery replaces the original pack in the Symbol MC9000 and MC9000S short terminal series handheld computers. It fits the MC9060 and MC9063 short terminal variants as well. OEM part numbers covered include 21-62960-01, 21-62960-02, 82-101606-01, and BTRY-MC90SAB00-01.
- MC9000 short terminal platform fit: The short terminal variants share a common battery bay geometry and voltage rail. The BMS handshake on each model expects the same 7.4V nominal and cell configuration, so one pack covers the MC9000S, MC9060, and MC9063 without modification.
- Bench tested on actual hardware: We ran this pack through full charge and discharge cycles on MC9000S units. The BMS engaged cell balancing correctly, voltage held stable across both scan trigger and wireless radio draw, and cutoff thresholds triggered at expected low-voltage limits.
- First-shift charging protocol: After installing the pack, seat the scanner in its cradle and complete a full charge cycle before pulling it for pick-and-pack work. Scan trigger inrush current peaks when the cell is near minimum — a pre-charged cell prevents the BMS from tripping on the first burst of the shift.
Cradle showing a charging error on a new pack
The MC9000 cradle communicates with the battery pack through gold contact pins on the underside of the terminal. Oxidation or debris on either the cradle contacts or the pack contacts increases resistance enough for the dock to flag a fault. This is not a battery defect — it is a contact issue. Wipe both the pack terminals and the cradle pins with a dry cloth, reseat the terminal firmly, and the charging indicator should clear within 30 seconds.
Scanner losing wireless connection during rapid scan bursts
During a fast scanning sequence, the MC9000 draws current simultaneously from the imager and the 802.11 radio. If cell voltage sags under that combined load, the radio drops its association before the BMS trips. This shows up as a disconnection mid-session rather than a full shutdown. Ensure the pack is at or above 7.0V before a high-frequency scanning shift — check the voltage readout in the device settings under Power menu before use.
