Compatible replacement battery

The Cameron Sino lithium polymer cell is built for Asus Eee Pad Transformer TF101 and TR101 tablets. It matches the original 7.4 V specification and fits the listed part numbers C21EP101, C21-EP101 and C22-EP101. The pack measures 136.93 x 102.58 x 4.22 mm and weighs 128.0 g.

Upgrade from depleted original

This unit replaces an ageing or failed factory battery in the same form factor. The jump is worth it when the tablet no longer holds a useful charge or shuts down under load. A fresh cell restores the designed run time without modifying the device.

Capacity and runtime headroom

Rated at 3300 mAh and 24.42 Wh the battery supports typical tablet workloads for several hours per cycle. It reaches full performance after two or three complete charge and discharge cycles. Heavy continuous use or high screen brightness will drain the pack faster.

Questions about this item

What are the exact dimensions of this 3300mAh 7.4V battery so I can confirm it fits my TF101 tablet?

The pack measures 136.93 mm by 102.58 mm by 4.22 mm and weighs 128.0 g, matching the original Eee Pad Transformer TF101 battery cavity.

Which step do people miss when installing this C21EP101 replacement battery?

The flexible connector must be fully seated in the motherboard socket; a partial insert leaves the tablet dead on first boot.

The manufacturer states two to three full charge and discharge cycles are needed for the new cell to deliver its full 24.42 Wh rating.
