The capacitance value is often marked using a 3 digit code. This works in the same way as resistor coding but using numbers instead of colours. The first 2 numbers give the value and the last number is the multiplier. These give the value in Picofarads (pF), e.g. code 103 = 1 0 000pF (=0.01uF). Alternatively the value may be marked directly, for example 2n2 is 2.2 Nanofarads (nF).
Ops, you are perfectly right! (http://en.wikipedia.org/wiki/Electronic_color_code) - when I googled I wrongly took the first page that showed that strange value "180pF"..

I'm finding an incredible number of errors in my diagram when I traced the circuit!! I must have been drunk in those last 3 days 'couse otherwise I should change hobby

Moreover, I found in my charger the red LED indicating the charge was going on and off every 5-10 minutes.. very odd. I should have found the cause: apart the bad solder job made on this board, one of the wires going to the battery terminals is burnt inside, the insulator is transparent, and is possible to see a black area....

I'll fix that, and other issue; meanwhile I'm correcting the diagram of the circuit inside LTspice and publish new finding - for now just assume the material linked is.. "terribly" wrong
