Purpose-built replacement
This lithium-polymer pack is engineered as a direct replacement for Besam automatic door-opener models EMC, EMCM and EU-EUD. It supplies 24.0 V and 300 mAh, matching the original electrical specification so the operator receives the correct voltage and capacity without adaptation.
Ready-to-fit construction
The cell arrives with a fully decoded protection chip that communicates with the host controller exactly like the factory unit. Over-charge, over-discharge, over-voltage and short-circuit safeguards are integrated, and the pack is cushioned in shock-absorbing foam for transit protection.
Capacity and limits
At 7.20 Wh the battery supports normal daily cycling of the door operator; extended hold-open periods or high-traffic installations will deplete the reserve faster. The 81.25 × 29.46 × 29.10 mm footprint fits the designated compartment, so larger-capacity alternatives cannot be accommodated without mechanical changes.

Questions about this item
How often will the 300mAh lithium-polymer cell need replacing in a Besam EMC door operator?
Typical cycle life for this chemistry is several hundred full charge-discharge cycles; with daily automatic-door use the pack usually lasts multiple years before capacity drops below useful levels.
What is the first limit reached when the battery powers the motor continuously?
The 7.20 Wh capacity is the limiting factor; sustained high-current draw will deplete the 300 mAh charge well before thermal limits are reached.
Does the pack generate noticeable heat or noise during all-day operation?
No moving parts and low internal resistance mean silent running; only a slight warmth appears under heavy load, well within the normal operating range for lithium-polymer cells.
