Direct replacement for Jabra 9120 and 9125

This Centenex Electronics lithium-polymer battery replaces the original AHB602823, 14151-01 and SG081003 cells used in Jabra 9120, 9125, GN-9120 and GN-9125 headset systems. It restores talk time for office workers and call-centre agents who rely on these specific DECT headsets daily.

Low self-discharge chemistry runs cool

The 340mAh 3.7V pack delivers 1.3 WHr without generating noticeable heat during charging or extended calls. Internal resistance stays low so the headset does not warm against the ear and no audible whine appears from the tiny protection circuit.

Slim 30 x 28 x 6.5 mm pack fits the original cavity

At 6.5 mm thick the cell slides into the existing battery compartment without forcing the cover or stressing the connector ribbon. The two-wire JST-style lead plugs straight onto the board so installation takes only a screwdriver and a minute of care.

Questions about this item

How do I install the battery in my Jabra 9120 headset?

Open the headset battery compartment, disconnect the old pack, and connect this 3.7 V 340 mAh lithium polymer unit matching the original polarity; the step users often miss is routing the wires so the cover closes without pinching them.

When will this battery need replacement?

The 1.3 Wh lithium polymer cell gradually loses capacity over repeated charge cycles; when talk time becomes too short for daily use, swap in a fresh pack.

What runtime limit appears first during a long call?

The 340 mAh capacity sets the maximum continuous talk time; once depleted the headset powers off until recharged.
