Replacement Battery for Jabra Engage 65 and 75

This 14151-09 battery pack replaces the original power source in Jabra Engage 65 Stereo, 75 Mono and 75 Stereo wireless headsets. It is a proprietary lithium-ion cell rated at 3.8 V DC with a capacity of 290 mAh. The pack is rechargeable and carries WEEE environmental certification. Buyers with other headset models cannot use this part.

Proprietary Form Factor Limits Interchangeability

The battery uses a proprietary size that fits only the listed Engage models. It cannot be swapped with standard cylindrical or prismatic cells. The fixed voltage and capacity are calibrated for the headset's power management, so third-party alternatives with different ratings may cause incorrect charge reporting or reduced runtime. No adapter or converter exists for this interface.

290 mAh Capacity Determines Talk Time

The single specification that decides suitability is the 290 mAh capacity at 3.8 V DC. This figure sets the maximum energy available between charges for the compatible Engage 65 and 75 headsets. If the original battery held more charge, this replacement will not restore the initial runtime. Buyers needing longer operation per charge cannot meet that need with this pack.
