I need to develop a 6V, 4.5AH, Sealed lead Acid battery charger. In which, 1. The charger indicator LED will turn ON only after connecting the battery. 2. There will be two LED’s in the charger. 3. One is for low battery indication (RED or Yellow LED)[ below 5 volt]. 4. One is for full battery indication [Greater than 6 or 6.5 volt, current consumption will less]. If anyone can help me, I will be grateful to you.
