“XPS 15 9530” actually refers to two different hardware generations. The newer P91F / P91F004 / P91F005 layout uses a modern thin internal pack (e.g., P0FWH 90Wh), while the legacy, End-of-Life P31F / P31F001 platform from earlier years used either a 61Wh (T0TRM) or a 91Wh (245RR) battery.
Before you buy: confirm your exact platform code (P91F or P31F) and/or your battery part number (P/N) and then search our store to find the right match.

Why are there two “XPS 15 9530” generations?
Dell reused the “9530” naming across very different internal layouts. The P31F (legacy) machines are from earlier years and reached End-of-Life; they used either 61Wh or 91Wh batteries with a different chassis footprint.
The P91F (new) 9530 is the latest family design with a thin, wide internal pack around 90Wh. Batteries are not cross-compatible between P31F and P91F.

How to confirm your exact 9530 version
- Check the platform code on the bottom cover or in BIOS: P91F (new) vs P31F (legacy/EOL).
- Read the battery label on your current pack: look for P/N such as P0FWH, 245RR, or T0TRM.
- Use Dell’s Service Tag on the support site to view originally configured parts.
- Search our store with your P/N or “XPS 15 9530 P91F” / “9530 P31F” to land on the right listing.
DIY overview (both platforms)
Skill: intermediate. If the battery is swollen or your device is under warranty, use professional service.
- Shut down, unplug the charger and all accessories. Work on a clean, hard surface.
- Remove bottom cover (Torx T5 on newer chassis); keep track of screw lengths/positions.
- Disconnect the battery connector from the motherboard (remove any brackets/shields first).
- Unscrew and lift out the old pack; place the new battery, align, and re-install screws.
- Reconnect, reassemble, then perform 1–2 full charge/discharge cycles to help the OS re-estimate capacity.
