Tell us about yourself!
thank you very much sir, I'll try to make one. Uhmm.. any recommendation where i could add the timer in the circuit diagram you shown? I love electricals/electronics but I'm just a beginner. There are circuits I browsed on the net and this one you have is the simplest charger circuit I found, while the other ones have this IC parts that I was trying to analyze the works, you know.. kinda like catching a cheeta in the amazon!
that was also what I'm planning to do and cutting the AC mains is the safest way. thank you and I appreciate that much sir.
hi sircan this charger work with 12V 100Ah valve regulated battery? i bought an old battery from a junk shop nearby. i will use it as a backup power source when brownouts occur here in our place. i can't find removable caps on these batteries for adding water, its like a sealed type battery and only the two terminals are present on both ends.
