Can anyone tell me the purpose of BT1 from which I was able to decipher from the p/n on the unit is actually a fast capacitor.

It appears to be a GC5.5V..... however I cannot make out the value in capacitance. I've only been able to find a replacement with a value of 0.22F.

It appears that the original may not be the same capacitance, however I cannot read all of the p/n as the print is very small even with his resolution images.

The part is circled.
