It depends on the exact generation, because the HP 200 line spans removable and internal designs. Modern HP 200 models like the 250 and 255 G7 and later commonly use an internal 3-cell pack rated around 11.55V and about 41.9 Wh. Older G1 through G5 units often use an external, user-removable 4-cell pack rated near 14.8V. The best way to confirm is to read the code printed on your current battery and match your G-number. Replacement options in this category run from $56.99 to $61.99.

Start by locating the exact “G” number on a label on the bottom of the laptop, for example HP 250 G7 or HP 255 G8, since the 200 series changes batteries by generation. Next, check whether your old pack snaps out from the outside (older G1 through G5) or sits inside behind the back panel (G6 and newer). The most reliable step is to read the battery code printed on your current pack and match that exact part. With your G-number and battery type, you can pinpoint the correct replacement.

HP 200 replacement batteries in this category range from $56.99 to $61.99. The exact price depends on which generation and pack your model takes, since older removable 4-cell packs and newer internal 3-cell packs differ in design and capacity. To make sure you are pricing the right part, confirm your exact “G” number (for example HP 250 G7) and whether your battery is external or internal before you order, so you match the pack that fits your machine.

No, not across the whole line. The HP 200 series transitioned from external, user-removable 4-cell packs on older G1 through G5 models to internal 3-cell packs (around 11.55V and 41.9 Wh) on G6 and newer models, so they are not cross-compatible. Even two units with the same model number, like an HP 250 G3 and an HP 250 G7, can take different batteries. Always match your exact “G” number and the code printed on your current pack rather than relying on the model name alone.

The main differences come down to size, platform, and generation rather than the sub-series name. The 240 and 245 are 14-inch units while the 250 and 255 are 15.6 inches to 16 inches, and the 245 and 255 use AMD platforms versus Intel on the 240 and 250. Across all of them, older G1 through G5 models tend to use removable 4-cell packs near 14.8V, while G6 and newer use internal 3-cell packs around 11.55V and 41.9 Wh. Match your specific generation to get the right pack.

Read it directly off your current battery, where you will see a code such as HT03XL printed on the pack. On internal models you will need to remove the back panel to see it, while on older removable models you can slide the pack out and read the label. A single battery can carry several equivalent part numbers, for example HT03XL also appears as HSTNN-DB8R, HSTNN-LB8M, L11119-855, and L11421-2C2. Matching any of those codes plus your exact “G” number confirms the correct part.

Yes, in most cases. On older G1 through G5 models the 4-cell pack often snaps out from the outside with a release latch, so no tools are needed. On G6 and newer models the 3-cell internal pack (around 11.55V and 41.9 Wh) sits behind the bottom panel, so you unscrew and remove the back cover, disconnect the battery cable, and swap the pack. Check whether your unit is external or internal first, and read the old battery code like HT03XL so you install the matching replacement.

Watch for runtime dropping well below normal, the laptop shutting down suddenly even when the charge reads above zero, or the system staying alive only while plugged in. A pack that no longer holds its rated capacity (for example far under the roughly 41.9 Wh of a modern HT03XL) is a clear sign. You may also see the operating system flag the battery health as poor or report a low charge ceiling. If you notice these, match your exact “G” number and battery code, then choose a replacement from the $56.99 to $61.99 range.
