SAMSUNG SM-N960 Galaxy Note 9 cell phone battery 4000mAh 3.85V EB-BN965ABU

Samsung Galaxy Note 9 replacement battery

This original Samsung EB-BN965ABU battery restores the factory power capacity of the Galaxy Note 9 SM-N960. It is intended for owners whose original cell no longer holds a useful charge. The lithium-ion pack delivers the same 4000 mAh rating at 3.85 V that the phone was designed around. No modifications or adapters are required for installation.

4000 mAh capacity and 15.40 Wh energy rating

The 4000 mAh cell provides a full day of typical mixed use including screen time, background sync and S Pen features. Heavy gaming, continuous navigation or maximum brightness will drain the pack faster and may require a mid-day top-up. The 3.85 V nominal voltage matches the handset's power-management profile exactly. Capacity naturally declines over repeated charge cycles as with all lithium-ion chemistry.

Upgrades a degraded or swollen original cell

This unit replaces the factory battery when runtime has dropped noticeably or the back cover has lifted due to swelling. The jump is worth it when the phone otherwise meets your needs but cannot survive a workday unplugged. It is not for users who need more capacity than the original 4000 mAh design allows. Professional fitting is recommended because the Note 9 uses adhesive seals for water resistance.
