Here is the circuit diagram of a simple and straight forward 12 V battery charger circuit with diagram. 12v 65 ah ka battery kese charge kar sakte he….12 v trnsformer se direct charge hoga kya? Hi friend,I want to make a stand alone 6v bike battery charger cum DC to AC-5A circuit.Could you please help me? Have you a modified Circuit to show the placement and value of the resistor mentioned by the person “Leandro” ? Also I am wanting to also build a 6 volt charger, for a 6v Gell type of battery, similar in size to a motor bike battery. Can you tell me the Different Transformer and Resistor Value, and whether I should fit a Zenner in the circuit ??? The circuit given here is a current limited lead acid battery charger built around the famous variable voltage regulator IC LM 317. To setup the charging voltage, power ONĀ  the charger and hook up a voltmeter across the output terminals and adjust R4 to make the voltmeter read 28V. I Have 36 volt 10 AH lithium battery, can I modif 24V lead acid battery charger circuit, to charger my 36 volt lithium battery? Hello engr,in this your design.can i use it to charge two 12V,26AH lead acid battery connected in series?.if no,what is the implication? Two 12 volts batteries of similar type and conditions can be charged up to a maximum of 7 AH only.
Hi joe Two 12 volts batteries of similar type and conditions can be charged up to a maximum of 7 AH only.


Hello engr,in this your design.can i use it to charge two 12V,26AH lead acid battery connected in series.if no,what will be the implication? Hello would you be kind enough to publish a 48v 5 to 10 amp lead acid battery charger circuit ?
This charger can be used for single 24 volt 7 AH battery or 2nos 12 volts 7AH batteries in series. Hi Tran you can charge 24volt 1.3AH battery (hope dry means dry fit lead acid gel cell) also.
Thank you very much for the charger circuit, i would like to use this circuit for charging two lead acid (12v 150A X 2)battery, for inverter. Sorry, I can’t quite follow how the resistor R2 provides 700mA, can you explain how the calculation is done please? I am looking to make an in-car charging system for an electric mobility scooter – it uses a 24v 10Ah battery. 1) can I substitute a 12v step-up DC-DC converter for the transformer and bridge rectifier section of your circuit to give me the DC input to the regulator, and what output voltage would the converter be required to supply? 2) what if any of the components of the regulated charger section would need to be changed to provide the correct output current and voltage?
I’m a big fan of your circuits,and I would like to ask about the possibility of modifying this circuit so we can control charging current (like a pot.
Hi Gangadhar you can but ensure the output voltage is adjusted to 14.2 volts without load with pot R4. This circuit can be used to charge all type of 12V rechargeable batteries including car batteries.


I build that one but i think the power of the battery go back to capacitor and i plan to put some diod in possitive side. If you want to limit to any other current level you have to use a sensing resistance and a transistor similar to the one used in our earlier article, which can be adopted for 12 volt also. As per your requirement of 26 AH a power pack capable of maximum current limit of 7 amps (9 amps preferred) is required.
Pls I need your urgent assistance in responding to these questions to enable me modify this circuit to do something else. I tried to insert a second BC547 as suggested (base of 2nd BC547 to base of 1st and emitter to the other emitter and collector to a led and a 2.7K resistor to C1 positive) to indicate full charge with no luck whatsoever! Pls can u send me the circuit diagram containing the charging indicator(green and red).pls send it to my email. The circuit is nothing but a 12V DC power supply with an ammeter for monitoring the charging current.
And i wonder to know if it isnt dangerous to make this circuit without any resistence like in this diagram. Diode D1 prevents the reverse flow of current from the battery when charger is switched OFF or when mains power is not available.
