Simple Lead Acid Battery Charger Circuit Diagram. This circuit can be used to charge rechargeable 12v lead acid batteries with a rating in the range of 1ah to 7ah. This circuit be lead acid battery charger again interesting instructable because it can charger get both of 12v sizes and 6v.
The maximum reverse leakage current of pb137 is 10µa at tj 0 to 40 c and v1 floating and vo 13 7v. One 555 timer ic is used for detecting the voltage level and relay is used to disconnect the ac input. When see the circuit you will think us uses integrated number highly popular circuit be lm317k again.
It gives 12 volt and 5 amps current for quick charging of the battery.
I recommend the circuit diagram below. The maximum reverse leakage current of pb137 is 10µa at tj 0 to 40 c and v1 floating and vo 13 7v. By change with switch only and this circuit charging with current about 1amp. This circuit be lead acid battery charger again interesting instructable because it can charger get both of 12v sizes and 6v.
