Replacement Battery for Samsung NP940 Series

This lithium-ion replacement battery is built for Samsung NP940X3M NP940X5M and NP940X5N notebooks. It matches the original AA-PBTN4LR and BA43-00386A part numbers. The unit ships new and ready to install. It restores mobile power for owners of these specific ultraportable models.

54 Wh Capacity and 15.4 V Output

The pack delivers 3530 mAh at 15.4 V for a total of 54 Wh of energy. That capacity supports typical office workloads and media playback for several hours. Runtime drops under sustained heavy loads such as video rendering or gaming. The fixed voltage means it cannot be used in laptops that require a different battery voltage.

Direct Swap for Worn AA-PBTN4LR Packs

This battery replaces an aging or failed AA-PBTN4LR BA43-00386A unit without modification. The upgrade is worthwhile when the original pack holds less than half its design charge or shuts down unexpectedly. It is not suitable for users who need a higher-capacity extended pack or a different form factor.
