15.4 V 54 Wh lithium-polymer replacement battery for Samsung NP940 series laptops

  • Battery TypeLithium Polymer
  • 4 V 54 Wh capacity powers compatible Samsung notebooks
  • Lithium-polymer chemistry delivers stable voltage and low self-discharge
  • Grade A cells support many charge cycles for long service life
  • FCC CE RoHS certified for safety and environmental compliance
  • Direct replacement for AA-PBTN4LR across listed NP940 models

Compatible Replacement Battery

This 15.4V 54Wh lithium-polymer battery replaces the original AA-PBTN4LR unit in Samsung NP940X3M and NP940X5 series notebooks. It is built with Grade A cells and carries FCC, CE and RoHS certification for safety compliance.

Upgrade From Depleted Original

The battery restores runtime when the factory pack no longer holds a useful charge. The jump is worth it when the laptop shuts down early, reports reduced capacity or cannot run unplugged for a typical session.

Capacity And Runtime Headroom

The 54Wh rating delivers the same energy envelope as the stock battery for compatible models. It runs out when workloads exceed the original design envelope or when the cell chemistry reaches its cycle limit after extended use.

  • Lithium-polymer chemistry delivers stable voltage and low self-discharge
  • Grade A cells support many charge cycles for long service life

Questions about this item

Does this 15.4V 54Wh lithium polymer battery physically fit the Samsung NP940X3M-K03US chassis?

Yes, it is built to the AA-PBTN4LR form factor and matches the NP940X3M, NP940X3M-K01US, NP940X3M-K02US, NP940X3M-K03US, NP940X5M and NP940X5N model families.

What is the correct installation step that users often skip when fitting this replacement battery?

After inserting the pack, reconnect the internal cable firmly and secure every screw before the first charge; skipping the cable seat causes the laptop to not recognise the new 54Wh cell.

How many charge cycles can the Grade A cells in this 15.4V pack deliver before a replacement is needed?

The manufacturer states more charging cycles than standard cells, and the 12-month warranty covers free replacement if capacity drops prematurely.
