Direct replacement for XPS 13 9315

This 51Wh lithium-ion cell matches the original 11.55V specification for the XPS 13 9315 series. It replaces part numbers YM15G, 0G9FHC, G9FHC and 31CP4/78/90. The black battery is supplied new and carries a 12-month warranty.

51Wh capacity for daily workloads

A 51Wh pack restores typical all-day runtime for web browsing, document editing and video playback. Heavy multi-tasking or sustained high brightness will drain the charge faster, so users running demanding workloads should keep a charger nearby.

Not compatible with 2-in-1 variant

This battery fits the standard XPS 13 9315 clamshell chassis only. It will not install in the 2-in-1 convertible model due to different internal layout. Buyers needing a battery for the 2-in-1 version must source a different part.

Questions about this item

Will the 11.55 V YM15G battery power my XPS 9315 alongside the original AC adapter without voltage conflict?

Yes, the 11.55 V lithium-ion cell matches the factory specification for the XPS 9315 series and works with the original charger.

How can I verify the 51 Wh capacity is reporting correctly after installing the YM15G battery?

Check the battery information in Windows Settings or BIOS; it should show 51 Wh design capacity and 11.55 V nominal voltage.

Does the package include the 31CP4/78/90 battery only, or are screws and tools supplied for the XPS 9315 swap?

The box contains one YM15G battery; mounting screws and opening tools are not included and must be sourced separately.
