Replacement battery for Samsung Notebook 9 2018

This 11.5 V lithium-polymer pack replaces the original AA-PBTN6EP unit in the Samsung Notebook 9 2018 NP900X5T series. It delivers 75 Wh and 6534 mAh of capacity in a black plug-and-play form factor. The battery is supplied new and carries a one-year warranty.

Plug-and-play lithium-polymer construction

The pack uses a lithium-polymer cell layout that fits the existing battery bay without modification. A matching connector allows direct installation once the back case is opened. Users should verify the original part number against the label before fitting the replacement.

Practical limits of the 11.5 V 75 Wh design

Capacity will degrade over repeated cycles; the supplier suggests an initial conditioning routine of discharging to 5 % then charging to 95 % for three to four cycles. Long-term storage requires a charge above 80 % at least once per month. Continuous connection to the AC adapter while the battery is fitted may accelerate wear.
