Thank you for your message. If you are cycling the battery AGM or gel then Sdr may contact you regarding your error report for clarification. I’ve just finished building this project within 3 days.

LED goes off at about every 10 seconds. This additional time for the calibration should be taken into consideration to your normal delivery time. Do you have any suggestions for more common components that will work as replacements for both? Posted February 21 edited.
Automatic 12V Lead Acid Battery Charger
All comments are being shown. Edited February 12 by marcelv.
Could you tell me how can I buy the parts for both Chargers – 1 and 2, please. How can I convert this circuit for charging my 6volt Battery?
Using a higher voltage secondary 16VV will allow you to charge 16V batteries sometimes used in racing applications. Can I use 12v 5Ah transformer instead of 4Ah? Hi, Have you had any posative comments from whom have built this charger? I need a bgx49 volt battery charger with amps capacity.
There is an entire series of BT Triacs. If better to add meter and display to indicated the charge voltage and current All the circuits this person has are bgx49.

Some component adjustments may be necessary to get the right threshold voltages. The output of a 12V transformer is somewhat higher then 12V.
Look up the current ratings of the two specified SCRs and find replacements with at least those current ratings. These chargers originally were charging four six volt gel cell batteries. Hi, can you use a higher amp transformer for say a 12AH battery without changing other components?
You mentioned in the notes that the transformer could brx449 changed to 18V output for charging xcr batteries. Please help me out. I tried giving some input on this awhile back with Ferrix but I dont think it went anywhere honestly. Sir I have a 18 volt output solar cell. You have to think, Switching power supplies were still in bx49 infancy when this circuit was designed.
The forum provides a more robust environment for discussion. You can find satisfactory replacements for less than a dollar at digiKey, Mouser, and many surplus outlets like All Electronics and Alltronics. I feel I will be cheating on myself if I don’t thank you people for this great and bdx49 work! Simply use a lower current output transformer and your high rate charge current will be lower too. I have two 24 volt industrial chargers, can i convert these for charging 12 volt automotive batteries?
A defect and a merit of the circuit: If the circuit is mounted in a case then a small fan might be necessary and can generally be powered right off the output of D1. Flooded and gel batteries src generally charged to
