Asus ROG laptops use internal lithium-ion batteries rated between 11.4 and 15.2 V with capacities from about 48 to 64 Wh, in 3-cell or 4-cell builds. Across this category there are 9 distinct part numbers covering roughly 650 models, including common ones like 0B200-02910000, 0B200-02730100, and 0B200-01940000. The exact pack depends on your sub-series and year, so check the part number printed on your current battery before you order.

Match your full model number (for example GA401IV or G531GT) to the part number printed on your current battery, such as 0B200-02730100 or FX504GD-0181D8750H. Asus ROG covers about 650 models across 9 part numbers, and two similar units can take different packs, so the model number alone is not enough. Flip the laptop, note the model on the base, then confirm the battery part number once you open the panel. That combination gets you the correct 11.4 to 15.2 V replacement.

Asus ROG replacement batteries in this category run from $57.99 to $84.99. Where your specific battery falls depends on the sub-series and capacity, since these packs range from about 48 to 64 Wh across 3-cell and 4-cell builds. A smaller Zephyrus pack tends toward the lower end, while a higher-capacity Strix or Strix Scar 4-cell unit sits higher. Confirm your part number (for example 0B200-02910000) to see the exact price for your model.

No, Asus ROG batteries are not universally interchangeable. This category alone uses 9 distinct part numbers across roughly 650 models, with voltages from 11.4 to 15.2 V and capacities from 48 to 64 Wh. A Strix model using 0B200-02910000 will not necessarily accept the 0B200-02730100 fitted to a similar laptop, because connector placement, capacity, and cell count differ. Always match your exact model and the part number printed on your existing battery rather than assuming one fits across the line.

The main differences are capacity, cell count, and physical fit. Portable Zephyrus and Flow models lean toward smaller internal packs near the 48 Wh end, while Strix and Strix Scar performance machines often use 4-cell packs closer to 64 Wh for higher power drain. Voltage across the line runs 11.4 to 15.2 V, and part numbers like 0B200-01940000 versus 0B200-02910000 reflect those differences. Each pack is shaped for its chassis, so a Flow battery will not fit a Strix Scar.

The part number is printed directly on the battery itself, in the 0B200-XXXXXXXX format (for example 0B200-02730100 or 0B200-01940000). To see it, power down, remove the bottom panel, and read the label on the pack. You can also check your full laptop model number on the base of the chassis, such as GA401IV or G531GT, then cross-reference it. Matching both the model and the printed battery number is the surest way to order the correct one of the 9 available parts.

Yes, most people can do this with a small Phillips screwdriver. Asus ROG batteries are internal, so you power down, remove the screws on the bottom panel, lift the cover, disconnect the old pack, and seat the replacement (for example a 0B200-02910000 unit). Sub-series like Flow with their compact 2-in-1 design can be more involved, so work slowly and keep track of screws. Confirm your 11.4 to 15.2 V replacement matches the original part number before you start.

Common signs include runtime dropping well below what you used to get, the laptop shutting off suddenly even with charge showing, and the system staying at a fixed percentage or refusing to charge past a point. You may also see a battery health warning in Windows or the MyAsus app. Since these packs are 48 to 64 Wh lithium-ion rated for limited charge cycles, performance fades over time. When runtime no longer supports your gaming or work, order a matching part such as 0B200-02730100.
