The Dell G G10 uses an internal lithium-ion battery that you access by removing the base cover with a Phillips head screwdriver. Because the G line splits across capacity tiers like 56Wh and 86Wh, the exact part number depends on your specific G10 configuration. The safest move is to flip the laptop over, remove the base panel, and read the part number printed directly on the pack so you order the matching family. Replacement batteries across the Dell G line run from $57.99 to $82.99.

Match your exact model number and the part number on the battery itself. Find the model on the bottom cover (for example G5 5590 or G15 5515), then remove the base panel and read the part number printed on the pack, such as 8FCTC, 33YDH, or XRGXX. This matters because similar looking machines differ: the G5 5590 ships in 60Wh and 90Wh versions. Confirming both the model and the printed part number keeps you from ordering a pack that does not fit the internal bracket.

Dell G replacement batteries run from $57.99 to $82.99, depending on which sub-series and capacity tier your laptop uses. Lower priced packs tend to be the 56Wh class (for example the 8FCTC or 33YDH), while higher capacity options like the 86Wh 69KF2 or 90Wh XRGXX sit toward the top of the range. Since the G line uses internal batteries, your final choice is driven by the exact part number printed on the pack inside your specific model.

No, Dell G batteries are not broadly interchangeable, even within the same sub-series. The G15, for instance, splits between the 8FCTC (56Wh) and the 69KF2 (86Wh), and those two are generally not swappable without changing internal components. The same applies to the G5 5590, which uses either a 60Wh (1F22N) or a 90Wh (XRGXX) pack. Always match the part number printed on your existing battery rather than assuming one G pack fits another.

The main differences are capacity, cell count, and the bracket the pack mounts to. Earlier tiers often used 56Wh packs like 33YDH or PVHT1, while later models offer 56Wh (8FCTC) or 86Wh (69KF2) options, and some carry 60Wh (1F22N) or 90Wh (XRGXX) versions. Higher capacity packs are physically different and may need different internal hardware. All are internal lithium-ion batteries, so the install method is similar even when the part numbers and sizes are not.

The part number is printed directly on the battery inside the laptop. Remove the base cover with a Phillips head screwdriver and look for a code such as 8FCTC, 33YDH, XRGXX, 1F22N, or 69KF2 on the pack label. You can also note your laptop model from the bottom cover (for example G15 5520) to cross check. Reading the printed part number is the most reliable way to confirm which battery family you need before ordering.

Yes, most Dell G batteries are owner replaceable with basic tools. These are internal lithium-ion packs, so you remove the base cover with a Phillips head screwdriver, disconnect the battery cable, unscrew the pack, and reverse the steps with the matching replacement. Confirm your part number first, such as 8FCTC (56Wh) or 69KF2 (86Wh), since higher capacity packs can use different internal brackets. Work on a clean surface and keep the screws organized so reassembly is straightforward.

Watch for runtime that drops far below normal, a charge that stalls or will not hold, sudden shutdowns, or a pack that the system flags as failing in Dell power diagnostics. If your G15 once ran for hours on its 56Wh (8FCTC) or 86Wh (69KF2) pack and now drains quickly, that capacity loss points to a tired battery. When you see these signs, match the part number printed on the current battery and order the same family, with prices from $57.99 to $82.99.
