12-volt batteries in many applications are being used , of course, to charge the battery in the case according to the quality of a circuit required LM317 circuits built with the 12v 7 y island 4 battery can charge this circuit equivalents ( 7,812 ) low-power ups, inverter devices is also used . Quite low in the cost of the battery charging circuit

Circuit 12 Volt and 12 Volt 4 Ah Ah AGM battery is designed for 7 .
This circuit , a voltage regulator output current is limited . Filling ( charging ) current of 600 mA – 700 mA between 4 and 12 Volt or 12 Volt 7 Ah Ah battery can charge like . Set the output voltage Volts 13.5 or 13.8 , you can keep permanently connected to the battery . (PC UPS battery and electric bicycle batteries are filled with the same logic . )
R3 for Vout = 13.8 volts , has been obtained by a parallel connection of three resistors . For R3 4K7 , 4K7 , 47K resistors connected in parallel are used, the output voltage of about 13.8 volts is achieved . LM317 , isolated to be connected to the cooler for cooling soğucu older processors used.
