Replacement battery for Samsung Notebook 9 Pen

The NShi AA-PBUN4KP is a new lithium-ion battery built to replace the original Samsung part number AA-PBUN4KP. It delivers 7.7V and 39Wh or 5120mAh of capacity for compatible Notebook 9 Pen models. This unit suits owners of listed NT930 and NP930 series laptops who need a direct replacement.

Practical limits of the 7.7V lithium-ion standard

The cell chemistry is rated for 500 charge cycles before capacity drops noticeably. The pack carries CE, FCC and RoHS certifications for safety and environmental compliance. A smart chip manages current and self-discharge. The supplier recommends discharging to 5 percent then cycling three to four times to reach full capacity.

Ensure your model appears in the compatible list covering NT930QAA, NT930QBE, NT930QBV and NP930QAA variants. Buyers who need a different voltage, capacity or form factor cannot use this pack.

Questions about this item

How do I confirm this AA-PBUN4KP battery fits my specific Samsung Notebook 9 Pen model?

Match the part number AA-PBUN4KP printed on your original battery, or check if your laptop model appears in the compatible list such as NT930QAA-K310, NP930QAA-K04 or NT930QBE-K38W.

What runtime can I expect from the 39Wh 5120mAh capacity in daily use?

The 39 watt-hour rating means the pack can deliver roughly 39 watts for one hour; actual runtime varies with screen brightness, workload and power settings.

What does the 7.7V rating mean for installation and charging?

The 7.7 volt output matches the original Samsung specification, so the battery charges through the laptop's standard charging circuit without any adapter changes.
