The HP G G10 uses a 10.8 V lithium-ion pack, typically a removable 6-cell or 9-cell unit that snaps into the underside of the laptop. Capacity in this line ranges from about 56 Wh to 103 Wh, so the exact watt-hour rating depends on your configuration. Common part numbers across the HP G line include HSTNN-DB72 and HSTNN-IB72. Check the label on your existing battery against the part number printed on it before ordering so you get the correct G10 pack.

Match your exact model and sub-series, then confirm the part number on your current battery. The HP G line spans 17 distinct part numbers covering about 1,580 compatible models, so close machines can take different packs. Flip the laptop over and read the part number printed on the existing battery or the service label, such as HSTNN-Q36C or HP484170-001. All packs here are 10.8 V lithium-ion, but capacity ranges from roughly 56 Wh to 103 Wh, so the printed number is the surest way to order right.

A HP G replacement battery costs $55.99 in this catalog. That single price covers the lithium-ion packs across the line, from the lower-capacity 56 Wh units up to the larger 103 Wh options. Because pricing is consistent, your main job is matching the correct part number for your sub-series, for example HSTNN-DB72 or HP010515-DK023R11, rather than comparing prices. Confirm your exact model first so the pack you order fits and connects properly.

Not broadly. The HP G line uses 17 different part numbers across roughly 1,580 models, so a battery from one sub-series often will not fit another even when the laptops look alike. They all share a 10.8 V rating, but cell count (6 or 9) and capacity (about 56 Wh to 103 Wh) differ, along with the physical connector and housing. Always verify the part number, such as HSTNN-IB72 or HP484170-001, against your current battery before assuming two packs are compatible.

Cell count, capacity, and how the battery installs differ across the G10, Gram, GT73, G12, G30, and G20 sub-series. Some use external, removable packs that snap into the underside, while others sit behind the base cover and need a few screws removed. Capacity ranges from about 56 Wh on lighter models to 103 Wh on higher-end units, all at 10.8 V. Part numbers like HSTNN-DB72 and HSTNN-Q36C map to specific sub-series, so the right pack depends on which model you own.

Look on the battery itself or the laptop service label. On models with a removable pack, flip the laptop over, release the battery, and read the printed code, such as 593553-001 style numbers or HSTNN-DB72. On units with an internal battery, the part number may appear on the base cover label or inside near the pack. You can also check the original box or your purchase records. Matching that exact code, like HP010515-DK023R11, ensures you order the correct 10.8 V lithium-ion battery.

Yes, in most cases. Many HP G models, including external-pack sub-series, use a removable 10.8 V battery that releases with a latch on the underside, so you can swap it in seconds with no tools. Other sub-series house the battery behind the base cover, which means removing a few screws and lifting the panel. Either way, power down and unplug first, confirm your part number such as HSTNN-IB72, and seat the new pack firmly until it clicks or connects.

Sharply reduced runtime is the clearest sign, for example a pack that once lasted hours now draining in well under one. Watch for a battery that will not charge past a low percentage, sudden shutdowns even with charge remaining, or a system warning to replace the battery. Physical changes like a pack that no longer seats flush also point to replacement. Since these 10.8 V lithium-ion units range from about 56 Wh to 103 Wh, an aging pack holds far less than its rated capacity over time.
