Q1 will need a heatsink. Close An error occurred, your message could not be sent. Yes you’re right, unfortunately I’ve tried with a modern 2N, apparently with the same features but it does not work properly. So 4A is too high, do you src any idea to decrease it to around 0.

After the order has been placed for the calibrated version, the non-calibrated device will be sent out from our warehouse to the calibration institute of Intertek Calibration service in process at Intertek Creating the certificate for end user The device will be repacked and sent directly to the end user.

Can you please provide me some check points to make sure that what I have wired is correct. Have to find the sweet spot To modify the automatic 12V lead Acid battery charger to become a 24V lead Acid charger, do U need to recoil the transformer? Thanks in advance Ramesh. And how long will it take to fully charge the 12V battery?

Does this circuit really works? By macalle69February 25, in Compact Mac. In this circuit you suggested 12V ac Transformer, not to mention that the diodes will lower the output voltage also lead acid battery isn’t at 12V even when discharged, its around somewhat Please i would like to know what modifications i could make to the circuit to enable me charge 12v amps battery at a time.

Theory and procedures used. I need a battery charger that will run off of 25VDC. This is done mainly to prevent spam and other abuse.

Posted December 7, If the circuit is powered off, the battery should be disconnected from it’s output otherwise the circuit will drain the battery slowly. Btw, can’t find P diode so I use A instead. Monitor the charge with a voltmeter until the battery reaches the proper end voltage and then adjust the pot until the LED glows steadily. HI can this charger modified to give the battery charging level more than one green led and one red during charging process.

Please contact our partner Intertek directly for a re-calibration of your device: So when you do the math, to match impedence, that means the old SCR requires 2mA of threshold at 10Ohms, whereas the newer replacements are uA at 10ohms.

Been using this circuit to charge batteries for nearly 10 years. The price for the calibration service is already included in the final price for calibrated version. Can u send me,the pcb layout of this project The charging current was about 20mA. The answer for both topic is yes.

Thyristors

There is nothing at all critical about the SCRs used in this circuit. The Intertek calibration certificates include: Hi, How can we add the 12v battery charger to the inverter to continue to charge the batteries while converting power from the battery to v. As I’m sure the notes say, the output is dependent on the size of the transformer up to 5A. On Q1 pin 1, 8.

Do you have any suggestion? Hello, and thanks for a good circuit, it is easy to build and to modify’ I’ve made two of these and two of my friends are very happy. Next time I make another I’ll add volt and amp gauges.

Thanks a lot fot the circuit, i have a question: Please I need help for their substitute. Adding the diode would prevent this circuit from working. Please I will be glad if my question is answer as soon as possible. Bbrx49 was another thread on this somewhere and turns out that this part is pretty picky, it wont go into regulation with modern substitutes. Simply use a lower current output transformer and your high rate charge current will be lower too. This is great but for 12v Ah battery it does not work?

I build this project exactly like in description. Would this design work to maybe charge electric scooter batteries? Problem is I have very little regulation on RPx to adjust the 5V, voltages are 5.
