It depends on the exact HP Notebook X2 model, since this line covers 15 distinct part numbers across about 391 compatible machines. A 10-inch Pavilion x2 commonly uses a DO02XL pack near 33 to 35 Wh, while a 12-inch Pavilion x2 uses a GI02XL around 33 to 36 Wh at 7.6V, and Elite x2 1012 builds often use MG04XL packs at 40 Wh or higher. Common part numbers in this category include HSTNN-IB7N and HSTNN-DB8A. Match your full model number to be sure.

Start with your full model number, found on a label on the back of the tablet section (it reads like “10-n130ca”). Then match it to the printed battery part number, such as DO02XL for many 10-inch Pavilion x2 units or GI02XL for 12-inch versions. Because this line spans 7.4 to 19.0 volts and about 30 to 98 Wh, voltage and capacity vary a lot. Confirming both the model number and the part number stamped on your old pack prevents a mismatch.

HP Notebook X2 replacement batteries in this category are priced at $64.99. That single price covers the range of 15 part numbers spanning the 10-inch and 12-inch Pavilion x2, Spectre x2, and Elite x2 builds. Since the cost is the same across the lineup, your main task is matching the correct part number (for example HSTNN-IB45 or HSTNN-I43C) to your exact model rather than weighing price differences.

No, they are generally not interchangeable across sub-series or sizes. A 10-inch Pavilion x2 DO02XL pack will not fit a 12-inch Pavilion x2 that uses a GI02XL, even though the machines look similar. Voltage also varies, with some Pavilion x2 packs near 7.6V and others in this category reaching up to 19.0 volts. With 15 distinct part numbers across roughly 391 models, you should always confirm the exact part number printed on your existing battery before ordering.

The main differences are capacity, voltage, cell count, and physical fit. Pavilion x2 packs are budget-focused, often 2-cell in the 33 to 36 Wh range, with 10-inch (DO02XL) and 12-inch (GI02XL) versions being entirely different parts. Spectre x2 and Elite x2 are premium and business builds that typically use higher capacity packs at 40 Wh or more, such as MG04XL on the Elite x2 1012 G1. Capacity across the full category runs from about 30 to 98 Wh, so the sub-series sets the spec.

Look in two places. First, check the label printed directly on the battery itself, which lists codes like DO02XL, GI02XL, or MG04XL plus an HSTNN reference such as HSTNN-IB7N. Second, find your full laptop model number on the back of the tablet section (it reads like “10-n130ca”), which maps to the correct part. On these detachable units the battery sits inside the tablet body, so you may need to open the back cover to read the label.

Yes, with some care. These are internal lithium-ion packs, so you will need to open the tablet section using a small screwdriver set, often a Phillips #0 or Torx, to remove the bezel or back cover. Because the keyboard detaches separately, the main battery lives in the tablet body, not the keyboard. Confirm your part number first, for example DO02XL on a 10-inch Pavilion x2, then work slowly to release any clips or adhesive holding the panel.

Watch for runtime that drops sharply from what you remember, the laptop shutting down well above zero percent, or the system staying on only while plugged in. A battery that no longer holds a charge or reports very low capacity against its rated value (for example a 33 to 36 Wh Pavilion x2 pack delivering a fraction of that) is a clear sign. If the tablet section feels unusually warm during light use or the charge percentage jumps erratically, it is time to plan a replacement.
