That depends on which Ultrabook you have, since the line spans XPS, Latitude, and Inspiron models from about 2011 onward. An XPS 13 9343 commonly uses a JD25G or 90V7W pack, a Latitude E7470 uses the R97YT, and an older Latitude E7240 uses the 4F5YV. All are internal lithium-ion or lithium-polymer packs. Match your exact model and the part number printed on the pack before you buy, since these batteries are not shared across families. Prices in this category run from $58.99 to $93.99.

Start with your exact model number and the part number printed on the existing battery pack (often shown as “Type Number”). You can also look up the laptop’s Service Tag on the Dell Support website to confirm the correct battery. Cross-reference that number against listings here, since families like JD25G (XPS 13) and R97YT (Latitude E7470) fit only specific models. Matching the printed part number is the most reliable method because similar looking laptops in this line take different packs.

Dell Ultrabook replacement batteries in this category run from $58.99 to $93.99. The exact price depends on your sub-series and model, since an XPS polymer pack, a Latitude E-series pack like the R97YT, and an Inspiron pack are built to different specifications and capacities. Confirm your part number first, then you can match it to the right listing and price within that range.

No, they are not interchangeable across the line. Each sub-series and generation uses its own internal pack with a specific shape, connector, and capacity. For example, the XPS 13 9343 uses a JD25G or 90V7W, while the Latitude E7470 uses the R97YT, and these will not swap into each other. Even within one family, part numbers change by model year, so always confirm the number printed on your current battery before ordering a replacement.

The XPS line uses high-density polymer packs designed for premium, ultrathin chassis (part families like JD25G, TP1GT, and 6NCPJ). The Latitude line favors robust internal packs built for long service life, such as the R97YT for the E7470 or 4F5YV for the E7240 and E7440. The Inspiron line uses internal packs whose form factor varies by generation (families like N9XX1, R05P0, and F62G0). Capacity, connector, and physical size differ across all three, so they do not cross over.

The part number is almost always printed directly on the battery pack, often labeled as “Type Number,” for example R97YT or JD25G. To read it you typically open the bottom panel of the laptop. You can also confirm the correct battery by entering your laptop’s Service Tag on the Dell Support website. Either method gives you the exact number you need, which matters because part numbers vary by sub-series and model year across this line.

Yes, in most cases you can. Dell Ultrabooks use internal batteries, so you remove the bottom panel to reach the pack, usually with a Torx T5 or Phillips head screwdriver. Disconnect the battery cable, unscrew the pack, and seat the new one (such as a JD25G for an XPS 13 or R97YT for a Latitude E7470) in the same position. Work slowly, keep track of the screws, and confirm your part number matches before you start.

Watch for runtime that drops sharply, a battery that drains quickly even after a full charge, or a laptop that shuts off unexpectedly when unplugged. You may also see the system stay pinned near a low percentage or report a low maximum capacity in Windows battery diagnostics. If your XPS, Latitude, or Inspiron only runs for a short time off the charger, it is likely time for a replacement pack in the $58.99 to $93.99 range that matches your model.
