The HP X360 uses a lithium-ion battery rated between 7.6 and 11.4 V and roughly 32 to 56 Wh, depending on the exact model and sub-series. Common part numbers across this line include HSTNN-LB6P, HSTNN-LB7L, and HSTNN-LB7B. Because the X360 name covers Pavilion, Envy, and Spectre tiers across many years, there is no single universal pack. Check the label on your current battery or the bottom of your laptop for the full model number, then match it to the correct part. The price is $34.99.

Find your full model number on the bottom of the laptop (for example 13-ae010ca or 15m-ee0013dx), then match it to the listed part. The HP X360 line spans about 169 models, so the same series name can map to different batteries. You can also open the laptop and read the part number printed on the existing pack, such as HSTNN-LB6P or HSTNN-LB7L. Matching by exact model number is the most reliable method, since voltage ranges from 7.6 to 11.4 V across the family.

HP X360 replacement batteries are priced at $34.99. That single price covers the three part numbers stocked for this line, HSTNN-LB6P, HSTNN-LB7L, and HSTNN-LB7B, which together fit about 169 compatible models. Since the price is consistent, your main task is confirming which part number matches your exact model rather than comparing costs. Use your laptop’s full model number or the label on the current battery to select correctly, and remember these packs run from 7.6 to 11.4 V and 32 to 56 Wh.

No, HP X360 batteries are not all interchangeable. The line uses three distinct part numbers, HSTNN-LB6P, HSTNN-LB7L, and HSTNN-LB7B, and they differ in voltage (7.6 to 11.4 V) and capacity (about 32 to 56 Wh). A Pavilion model and a Spectre model under the same X360 name can require different packs, and even two similar 13-inch units may not share one. Always confirm the part number against your exact model number rather than assuming any X360 battery will fit.

The Pavilion, Envy, and Spectre tiers differ mainly in capacity and cell count. Pavilion models tend to use lower-capacity 3-cell packs, Envy balances with 3-cell or 4-cell options, and Spectre often carries higher-capacity 4-cell batteries closer to the 56 Wh end of the range. Voltage across the line spans 7.6 to 11.4 V. The three stocked part numbers, HSTNN-LB6P, HSTNN-LB7L, and HSTNN-LB7B, map to different models and years, so the sub-series helps narrow the search but the exact model number confirms the fit.

The part number is printed directly on the existing battery, so opening the base cover and reading the label is the surest method. Look for codes like HSTNN-LB6P, HSTNN-LB7L, or HSTNN-LB7B. You can also identify your laptop’s full model number on the sticker on the bottom of the machine (for example 15m-ee0013dx) and match it to the correct battery in our listings. Both routes work, and cross-checking the two helps confirm you are ordering the right pack from the three available.

Yes, most people can replace it themselves. On HP X360 models from 2017 onward, the battery is internal, so you remove the base cover, usually with a Phillips-head screwdriver, then disconnect and swap the pack. Confirm your part number first, whether it is HSTNN-LB6P, HSTNN-LB7L, or HSTNN-LB7B, and power down before opening the laptop. The packs run 7.6 to 11.4 V and 32 to 56 Wh. Work slowly when releasing the connector and seat the new battery firmly before reattaching the cover.

Watch for runtime dropping well below what you once had, the laptop shutting off suddenly even when it shows charge, or the battery refusing to hold a charge past a low percentage. Frequent need to stay plugged in is another clear sign. If you notice these symptoms, identify your model and order the matching part, HSTNN-LB6P, HSTNN-LB7L, or HSTNN-LB7B, all priced at $34.99. These lithium-ion packs (7.6 to 11.4 V, 32 to 56 Wh) naturally lose capacity over hundreds of charge cycles, so decline over time is expected.
