What battery does the VivoBook use?

The VivoBook uses an internal lithium-ion battery rated between 7.4 and 14.4 V with capacity around 24 to 42 Wh, usually in a 2-cell or 3-cell layout. Common part numbers across the line include B31N1637, 0B200-02960400, and 0B200-02560000. Because the series spans roughly 2679 models from 2012 onward, the correct pack depends on your exact model. Check the label on the bottom of the laptop and match the printed part number before you buy.

How do I find the right battery for my VivoBook model?

Match your exact model number, which is printed on a label on the bottom of the laptop (for example X512FA or M3500Q). That model maps to a specific part number such as B31N1637 or 0B200-02960000. With 34 distinct part numbers covering this line, similar-looking VivoBooks often take different batteries. You can also remove the existing pack and read the part number printed directly on it, then confirm the voltage (7.4 to 14.4 V) and capacity match.

How much does a VivoBook replacement battery cost?

VivoBook replacement batteries run from $51.99 to $82.99. Where a specific model falls in that range depends on its capacity (about 24 to 42 Wh), cell count, and the exact part number, such as 0B200-02920000 or B31N1637. Higher-capacity packs for larger or creator-focused models tend toward the upper end. Confirm your model number first so you are pricing the battery that actually fits your machine.

Are VivoBook batteries interchangeable?

No, VivoBook batteries are not universally interchangeable. The line uses 34 distinct part numbers across about 2679 models, with voltage spanning 7.4 to 14.4 V and capacity from roughly 24 to 42 Wh. A battery like B31N1637 will not fit a model designed for 0B200-02560000, even if the laptops look similar. Connector position, physical size, and electrical rating all have to match, so always confirm by exact model number and part number.

What differs between the VivoBook sub-series batteries?

Differences come down to voltage, capacity, cell count, and physical fit. Across the line, packs range from 7.4 to 14.4 V and roughly 24 to 42 Wh, with 2-cell designs common in standard models and higher-capacity packs in larger or creator-focused builds. Part numbers reflect these differences, so 0B200-02960400 and 0B110-00520200 are not cross-compatible. The safest approach is to match your exact model rather than assume a battery carries across the range.

Where do I find the battery part number?

Look on the label on the bottom of the laptop, which lists the model number, and on the battery itself once the bottom chassis is opened. The pack is printed with its part number, such as B31N1637 or 0B200-02920000, along with its voltage (7.4 to 14.4 V) and capacity in Wh. If you can read either the model number or the part number, you can confirm the correct match before ordering from the 34 available part numbers.

Can I replace the VivoBook battery myself?

Yes, in most cases. VivoBook laptops almost universally use internal lithium-ion batteries, so replacement means opening the bottom chassis, removing a few screws, disconnecting the old pack, and seating the new one. Confirm your part number first (for example 0B200-02960000 or B31N1637) so the connector and the 7.4 to 14.4 V rating match. Work with the laptop powered off and unplugged, and keep track of your screws since panel layouts vary by model.

What are the signs the battery needs replacing?

Watch for runtime that drops sharply from new, a charge that stalls below 100 percent, sudden shutdowns even with charge remaining, or a system that runs only while plugged in. Reported capacity falling well under the original rating (these packs are about 24 to 42 Wh) is another clear sign. If you see these symptoms, confirm your exact model and order the matching part number, such as B31N1637 or 0B200-02560000, in the $51.99 to $82.99 range.
