Replacement Battery For ASUSPRO B9440 Series

This 15.4V lithium-ion pack delivers 48Wh of capacity and fits the ASUSPRO B9440, B9440UA, B9440UAV, B9440FA and related sub-models listed in the compatibility table. It replaces part numbers C41N1619, C41PKCH and 0B200-02350100M. The unit ships new in black and carries a 12-month warranty.

Sustained Output Under Typical Workloads

The cell chemistry maintains a steady 15.4V rail during extended office tasks, video playback and light development work without the voltage sag seen in aged packs. Capacity remains consistent across the discharge curve so runtime predictions stay accurate throughout a full day away from mains power.

Thermals And Power Draw In Daily Use

Normal operation keeps the pack near ambient temperature thanks to the low internal resistance of the lithium-ion cells and the host laptop's existing thermal design. No additional fan noise or chassis heat is introduced and the battery draws only the current the system requests during typical productivity loads.

Questions about this item

Does the 15.4V 48Wh lithium-ion cell run hot during all-day use?

The pack is a standard 15.4V 48Wh lithium-ion unit; it warms under load like any laptop battery but has no active cooling of its own.

Must I already own a compatible ASUSPRO B9440-series chassis for this 0B200-02350100M pack to fit?

Yes — it only fits the listed B9440, B9440UA, B9440UAV, B9440FA and related sub-models.

Will the C41N1619 replacement charge correctly with the original 19V adapter kept from my older B9440?

The battery accepts the standard 19V charge profile used across the B9440 series, so the existing adapter works.
