Direct replacement for KRMT 23/43

This Estry battery pack replaces the original 671817.009 unit in KRMT 23/43, swiss 275 602 and D-SC1800BTx2-MOLEX/5239 devices. It delivers a nominal 2.4V output with a 2000mAh capacity for 4.8Wh of energy. The Ni-MH chemistry includes overcharge, over-discharge, over-voltage and short-circuit protection for safer operation.

Fits existing connector and enclosure

The pack uses the same MOLEX interface and measures 85.5 x 22.5 x 22.5mm, so it slots into the original compartment without rewiring or adapters. At 170.0g it matches the weight budget of the host equipment, leaving mounting points and cable routing unchanged. No extra chargers or firmware updates are required for installation.

Low heat and stable voltage under load

In normal use the Ni-MH cells run cool and maintain steady voltage across the discharge curve, reducing thermal stress on surrounding components. Built-in protection circuits prevent fault currents that could generate noise or excess power draw. The pack carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications for compliance and transport safety.

Questions about this item

How long will the 2000mAh Ni-MH pack run before voltage drops under continuous load?

The 2.4V 2000mAh Ni-MH pack delivers 4.8Wh; actual runtime depends on the device's current draw, but capacity is rated at 2000mAh.

Does the battery get hot or make noise during all-day operation in a KRMT 23/43 device?

Ni-MH chemistry runs silently; heat stays low at normal discharge rates, and the pack includes over-charge, over-discharge, over-voltage and short-circuit protection.

Must the KRMT 23/43 unit already have a MOLEX/5239 connector for this replacement to fit?

Yes, the pack uses a MOLEX/5239 connector matching part number 671817.009 for KRMT 23/43, swiss 275 602 and D-SC1800BTx2 models.
