i build the charger and just some questions, must the led flash from start or only when fully charged. i did drain a battery and tried it but still led flashes from start. how do u adjust the 1k pot and when? also im using a 1 amp ac transformer not 500 ma as mentioned as i see the current is regulated by the 1E8 res. the push switch i take is a latching one. heres the circuit. --- http://talkingelectronics.com/projects/BatteryCharger-12vSLA/BatteryCharger-12vSLA.html
