Cross-reference the original battery part numbers C12N1320, 0B200-00720100, 0B200-00720300 or 0B200-00720400 printed on the existing pack.

Questions about this item

Does the Estry C12N1320 battery pack include any tools or cables for installation?

The pack contains one lithium battery only; no tools, cables or adhesives are supplied, so you will need to source any required screwdrivers or opening picks separately.

Should I choose the 8350 mAh version or the 8150 mAh version listed in the specifications?

Both figures refer to the same physical cell; the 8350 mAh rating is the headline capacity while 8150 mAh appears in the detailed spec sheet, so there is no separate version to select.

What does the 30.97 Wh rating mean for runtime in an Asus Transformer Book T100?

At 3.8 V the cell stores 30.97 Wh; actual runtime depends on the tablet’s power draw, but the watt-hour figure lets you compare directly with the original battery’s Wh rating.
