Questions about this item

How long will the 54 Wh capacity run a Samsung Notebook 9 Pro under typical workloads?

The 54 Wh pack is rated for the same capacity as the original AA-PBTN4LR, so it restores factory runtime on compatible NP940X3M, NP940X5M and NP940X5N models.

What connector does the AA-PBTN4LR use and will it plug straight into the motherboard?

It uses the original Samsung plug-and-play connector shown in the product images; alignment matches the factory battery socket on the listed Notebook 9 Pro series.

Will this battery fit inside the NP940X5M chassis without modifications?

Yes, the AA-PBTN4LR is built to the exact dimensions of the OEM pack for the NP940X3M, NP940X5M and NP940X5N families, so it seats in the standard battery bay.
