Direct replacement for EZBook FA3I266
The BTI DR-202 is a 9-cell lithium-ion battery built specifically for the EZBook FA3I266 notebook. It delivers 11.1V and 6600 mAh of capacity to restore the original runtime of the machine. Owners of this exact model can swap the old pack without adapters or configuration changes. Users of other laptops will find no compatibility here.
Steady output through a full day
The nine-cell design spreads the load across more cells, so voltage remains stable during long work sessions instead of sagging after a short burst. Lithium-ion chemistry keeps self-discharge low when the notebook sits idle between charges. The pack is rated for hundreds of full cycles before capacity drops noticeably. Heavy loads such as video playback or compiles draw clean current without sudden shutdowns.
Upgrade from a worn original pack
When the factory battery holds only a fraction of its first charge, this unit returns the notebook to its launch-day endurance. The jump is worth it if daily unplugged time has fallen below two hours or the system throttles on battery power. Machines that stay docked permanently gain no benefit from the swap. Buyers needing more capacity than 6600 mAh must look elsewhere.

It uses the notebook's original charging port and circuitry; no extra adapter is needed.
Will the 11.1 V, 6600 mAh battery work with the original power-management firmware on the EZBook FA3I266?
Yes, the voltage and cell count match the factory specification, so the existing firmware recognises it correctly.
