The fiio e11 is a brilliant portable headphone amplifier that provides more power to your headphones to drive them to their full potential without reaching high distortion levels. It also has three levels of bass boost you can select to increase the amount of subwoofer bass in your tracks. The fiio e11 operates on a small mobile phone sized battery similar to the Nokia BL-5B battery, which is 800 mAH and provides 3.7 volts. Thankfully to the clever design, this battery is easily replaceable, it is not soldered into the circuit board and no tools are required. You might want to replace the current battery in your fiio e11 portable headphone amplifier if the battery is not holding charge, or you want to increase the battery life by inserting a battery with more mAH.
1) Power off your fiio e11 amplifier by turning the volume knob all the way 'Clockwise'. You will hear a 'Click' sound and the blue power LED indicator will turn off. This is recommend to do because you can damage the internal capacitors if you remove the battery while the amp is switched on
2) Turn the fiio e11 amplifier upside-down, you will see a plastic cover that is covering the rear of the amp. This plastic cover is removable, underneath is the battery pack and the internal circuits. So remove the plastic cover, by inserting your finger nail into the gap found at the bottom and then pushing it upwards.
3) You will now see the battery pack inserted into the middle of the fiio e11 amplifier. Now that you have located it, use your finger to pry out the battery pack.
4) Now that you have removed the old battery pack, insert your new replacement battery pack into the compartment.
5) Replace the plastic cover you removed earlier on, by lining it up with the amp and pushing it down. Run your fingers all the way around the corners of the plastic cover to ensure that its locked in.
