Compatible EDAN monitors

This replacement battery fits EDAN IM20 and IM12 patient monitors that use part number TWSLB-012. It supplies 11.1 V and 2600 mAh for 28.86 Wh of runtime. The lithium-ion pack weighs 246.0 g and includes over-charge, over-discharge, over-voltage and short-circuit protection. It is certified to ISO9001, RoHS, CE, UN38.3 and MSDS standards.

Not for other brands

Buyers who need a power source for non-EDAN equipment or a different EDAN model should look elsewhere. The connector and pin-out are specific to the IM20 and IM12 series. Units requiring a higher capacity or a different voltage are not supported by this pack.

Voltage and capacity match

The 11.1 V, 2600 mAh rating must match the original battery label exactly. Verify the part number TWSLB-012 on your existing cell before ordering. A mismatch in voltage or capacity will prevent proper operation.

Questions about this item

How much heat or power draw should I expect from the 11.1 V 2600 mAh pack during a full day of use?

The 28.86 Wh lithium-ion cell delivers its rated capacity without active cooling; normal operation stays warm but not hot, and built-in over-voltage and short-circuit protection limits excess current draw.

What must I already own for this replacement to work in my device?

You need an EDAN IM20 or IM12 monitor that originally used the TWSLB-012 pack; the battery slides into the existing compartment and connects with the factory connector.

Will the 246.0 g pack fit and charge correctly in an older IM12 unit I still use?

Yes — the cell matches the original voltage, capacity and part number TWSLB-012, so the IM12 recognises it and the on-board charger completes a normal cycle.
