Compatible BLU Tablet Models

The Cameron Sino 680BT replacement battery fits the BLU TouchBook 8.0, TouchBook 8.0 3G, P220U, P220 and BT-E505 tablets. It is built for owners of those specific devices who need to restore original runtime. The 3300mAh capacity matches the factory specification for daily mobile use.

Replaces Worn Original Cells

This unit replaces the factory-installed battery when it no longer holds a useful charge after repeated cycles. The upgrade is worth it when the tablet shuts down early or requires constant tethering to a charger. A fresh 12.21Wh cell restores the expected unplugged operating time.

Steady Output During Extended Sessions

The battery delivers consistent voltage across the full discharge curve rather than sagging under load. Precision manufacturing keeps internal resistance low so the tablet maintains performance during long work or media sessions. Robust construction supports reliable day-to-day operation without sudden drops.

Questions about this item

Will the 680BT battery fit inside my BLU TouchBook 8.0 without any case modification?

The 680BT is built to the exact dimensions of the original BLU TouchBook 8.0 battery, so it slides into the existing compartment and the cover closes normally.

What is the correct way to install the 680BT, and which step do people often skip?

Power off the tablet, remove the back cover, disconnect the old pack, connect the new 680BT connector firmly, then reassemble; the step most often missed is pressing the connector fully home until it clicks.

How will I know when the 3300mAh 680BT needs replacing?

When the TouchBook 8.0 runs for noticeably less time on a full charge or shuts down unexpectedly at a reported 20–30 % level, the 680BT has reached the end of its useful life.
