It depends on the exact model, since the Asus Transformer name covers many devices. A T100TA uses the C12N1320 (about 8350mAh/31Wh), while a T100HA uses the C12N1435 or C21N1509. A Transformer Mini T102HA uses the C21N1533 or C21N1711, and a T200TA uses the larger two-piece C22-T200. Check the full model number on the back of your tablet, then match it to the correct part. Replacement batteries in this category run from $55.99 to $69.99.

Read the full model number printed on the back of the tablet, for example T100TA, T100HA, or T102HA, then match it to the part number for that specific model. The T100TA maps to the C12N1320, the T101HA to the C21N1601, and the T300 Chi to the C23-T300. Names alone are not enough, since the T100TA and T100HA take different batteries. Also note whether your keyboard portion holds its own cell, because that may be a separate part.

Replacement batteries in this category cost between $55.99 and $69.99. The exact price depends on your specific model and the battery it requires, since capacities differ across the line (for example, the T100TA carries a C12N1320 rated near 8350mAh/31Wh). To get the right price, confirm your full model number, such as T100TA or T102HA, and match it to the correct part number before ordering.

No, batteries are not interchangeable across the line, even between similarly named models. The T100TA uses the C12N1320, while the T100HA uses the C12N1435 or C21N1509, so they do not swap. The Transformer Mini T102HA uses the C21N1533 or C21N1711, and the T200TA uses the larger two-piece C22-T200. Always match the part number to your exact model rather than relying on a similar name or generation.

The Android Transformer Pad models (TF300, TF700) use parts like the C21-TF300T, while the Windows Transformer Book T-Series uses model-specific cells such as the C12N1320 (T100TA) or C22-T200 (T200TA, a larger two-piece battery). The Transformer Mini line (T102HA, T103H) uses the C21N1533 or C21N1711. Capacities and physical sizes vary by sub-series and year, so the cell that fits one body will not fit another. Confirm your exact model before choosing.

Look on the back of the tablet for the full model number (for example T100TA, T101HA, or T102HA), then match it to the battery part. The T100TA corresponds to the C12N1320, the T101HA to the C21N1601, and the Transformer Mini T102HA to the C21N1533 or C21N1711. If you open the tablet, the existing battery often has its part number printed directly on the cell label, which you can compare against your replacement.

Yes, with care, since most cells are internal and adhered inside the tablet body. You typically remove the back panel, disconnect the ribbon cable, and detach the existing battery before fitting the new one. The T100TA uses the C12N1320, while the T200TA can use the larger two-piece C22-T200, which takes extra attention during removal. Work slowly, use plastic pry tools, and confirm your model number first so you install the correct part.

Common signs include much shorter runtime than when new, the device shutting off well before reaching zero percent, or the battery not holding a charge. You may also see the tablet only run when plugged in. If your T100TA with the C12N1320 (about 8350mAh/31Wh) now lasts a fraction of its original time, the cell has likely worn down. Confirm your exact model number, then match it to the right replacement part, priced from $55.99 to $69.99.
