Direct replacement for JFC 7752 and 7941

This Estry lithium cell is built to the original specifications for Directed Electronics models JFC 7752 and JFC 7941. It arrives new and ready to install in compatible devices. The pack contains a single 120mAh battery rated at 3.7V with an energy content of .44Wh. ISO9001, RoHS, CE, UN38.3 and MSDS certifications confirm manufacturing quality and safety compliance.

120mAh capacity for low-draw applications

The cell delivers 120mAh at 3.7V, suitable for the remote or sensor designs that specify the JFC 7752 or 7941 part numbers. It provides enough headroom for typical standby and signalling cycles in those units. Runtime will fall short in devices that demand higher continuous current or larger capacity packs. Builders needing extended operation or a different form factor cannot use this cell.

Certified safety circuitry included

Each unit integrates overcharge, over-discharge, over-voltage and short-circuit protection to preserve cycle life and prevent damage. The protection board fits within the 24.7 x 20.3 x 3.7mm outline and 28.2g weight, so no extra space is required in the host device. No charger, cable or mounting hardware is supplied; the package contains only the battery itself.

Questions about this item

Will the 3.7 V 120 mAh lithium cell fit inside my JFC 7752 remote without modification?

The cell measures 24.7 x 20.3 x 3.7 mm and is built to the original specifications for the JFC 7752 and JFC 7941 models, so it slots straight into the existing battery compartment.

How can I confirm the 0.44 Wh pack is functioning correctly after installation?

The remote should power on immediately, hold a charge through normal use, and the built-in protection circuit prevents over-charge, over-discharge and short-circuit events.

Does the single pack include any connectors, screws or tools, or must I source them separately?

Only the 28.2 g lithium battery is supplied; no wiring harness, fasteners or opening tools are included, so reuse the original hardware from the JFC unit.
