Battery charging Circuit Required

[Faheem Saleh]

Hi! I need an automatic battery charging circuit for a 12V battery that charges the battery automatically when its voltage drops down to a threshold value (say 10V) and stops when it is fully charged at about 14V. can somebody help me in this regard? Thanks

Why to wait threshold of 10V, by the way voltage 10V is wrong (for starter minimum 11,9V for deep cycle 10,5V). If there is power source for charger, charger should charge battery without waiting lower voltage levels.
