Direct replacement for Beamex MC2 series

The Cameron Sino MC28B is a nickel-zinc battery built to match the original 3600mAh 3.6V specification for Beamex MC2-IS, MC2-MF, MC2-PE and MC2-TE instruments. It delivers 12.96Wh of energy in a 68.85 x 50.80 x 17.70mm pack weighing 158.4g. A fully decoded chip ensures the meter reads exactly like the factory cell.

Upgrade from worn or swollen original cells

If your existing Beamex battery no longer holds a full shift charge or shows physical swelling, this unit restores the rated 3600mAh capacity without modification. The jump is worth it when field run-time has dropped below the original 12.96Wh benchmark or when the safety certifications (ISO9001, RoHS, CE) on the old pack have expired.

Verify model number and connector orientation

Before ordering, confirm the device label reads MC2-IS, MC2-MF, MC2-PE or MC2-TE and that the original part number is MC28B or MC2BP. Check that the connector pins align with the replacement; the pack dimensions are fixed at 68.85 x 50.80 x 17.70mm. Allow two to three full charge cycles for the new cell to reach rated capacity.
