The Lenovo G10 uses an 11.1 V lithium-ion battery, typically a 6-cell pack in the roughly 48 to 58 Wh range. Many G10 units take a removable click-in style battery such as L11L6F01, which lifts out from the underside once the latch is released. Because part numbers vary by sub-series and production year, confirm the full model number on your laptop base before ordering. Replacement packs in this category run from $56.99 to $57.99.

Match the full model number printed on your laptop’s base (for example G50-70 or a 20xxx number) to the part number on the battery itself. The Lenovo G category covers about 10 models with 4 distinct part numbers, so the model name alone is not enough. Look for a number like L11L6F01 on your current pack, then confirm the voltage reads 11.1 V. Matching both the model and the part number prevents ordering a pack that physically will not fit your bay.

Lenovo G replacement batteries cost between $56.99 and $57.99 in this category. Pricing is consistent across the 4 part numbers because the packs share similar 11.1 V lithium-ion construction and capacities of about 48 to 58 Wh. The exact figure depends on which sub-series your model falls under, so confirm your part number such as L11L6F01 to see the price for your specific pack.

No, Lenovo G batteries are not all interchangeable, even within the same series. This category uses 4 distinct part numbers across roughly 10 models, and a pack built for one sub-series often will not fit another. For example, a G580-style L11L6F01 battery does not fit a later G50-70 model despite both belonging to the Lenovo G line. Always match your exact model number and the part number on your current 11.1 V pack before buying.

The main differences are part number, cell count, capacity, and how the battery installs. Across the G10, Gram, GT73, G12, G30, and G20 sub-series you will see lithium-ion packs at 11.1 V with capacities from about 48 to 58 Wh, but the specific part number (such as L11L6F01) changes by sub-series and year. Most use removable 6-cell packs that click in, while slimmer designs like the Gram tend to be internal and need partial disassembly to reach.

Find the part number printed directly on the battery label, which you reach by removing the pack or, on internal designs, opening the base panel. Look for a code such as L11L6F01 alongside the voltage rating of 11.1 V. The full laptop model number on the base of the chassis (for example G50-70 or a 20xxx series number) also helps confirm the match. Use both the model number and the battery part number together to order the correct pack.

Yes, on most Lenovo G models you can replace the battery yourself. Many use a removable click-in pack at 11.1 V that releases with a base latch and lifts out without tools, making the swap a one or two minute job. Slimmer designs like the Gram and some later units use internal batteries that require partial disassembly to access. Confirm whether your model takes a removable pack such as L11L6F01 before you start so you have the right tools ready.

Watch for run time dropping well below normal, the laptop shutting off unexpectedly even when the meter shows charge, or the system only working while plugged in. A battery that stops holding a charge or reports a much lower capacity than its rated 48 to 58 Wh is near the end of its life. If your 11.1 V pack such as L11L6F01 no longer powers the laptop away from an outlet, it is time to replace it. Match your exact model and part number for the correct fit.
