|This charger will charge any 12V lead acid battery including flooded, gel and AGM. It is fully automatic and will charge at a rate up to about 4A until the battery voltage reaches a preset point at which it will switch to a very low current float charge. If the battery voltage drops again the charger will begin charging until the voltage once again reaches the cut off point. In this way it can be left connected to a battery indefinitely to maintain full charge without causing damage. An LED indicates when the battery is fully charged.|

|Hi, Thank you for sharing this knowledge. Can you please help me with an information? I need a 12 volt battery charger with 12-14 amps capacity. From the schematic above, what are the components I need to change to achieve this? and what exact specs of the components? Many Thanks. Chris|
|i have a question. what if there is no available BRX49, is there any option that this circuit work? or what would i do of this problem?? please help me, i need an answer.. you are part of our project.. please reply asap. Godbless|
|thanks for your above chart it is clear but I really need 24 volts to charge 2 batteries at same time so plz can you just replace the required parts only on Description table or whole image itself. Actually I got 220 ac to 24 volt ac transformer i want to use this transformer for charging by converting into DC line..i n past I did lot but always some thing blows off..so plz if possible contact my email add..|
|can this circuit diagram suitable for ups charger?|
|asalamualaikum bro i have one prob on this circuit please tell me what is the substitute of BRX49 SCR ,,,,this ic is not available on my area so please guide me what can i use for its substitute.???|
|hi..... how to add 2 or 3 batterys to this same circuit........???|
|i can't found the TRIAC BT136 but can i use TRIAC BT139 instead of TRIAC BT136? and can i use BC548 or BC558 instead of BRX49 SCR? and can i use IN4004 diode instead of P600 Diode? please help me. i need to complete my project urgent.|
|i assembled a 12v charger only using 1no center tap 12-0-12 transformer 4amp and 8nos of power diode 4nos for each side and charged 120AH BATT WITHIN 8HOURS. CHARGING CURRENT FOUND 10AMP. NO MORE COMPONENT USED. WHAT WILL BE THE DEMERITS ON IT .|
|pls how can this circuit be reconfigured to charge two 12V/15Ah sealed lead -acid batteries using a 27 or 28 volts AC/DC converter|
|i made that cct n its working good, used full wave rectification coz D1 introduce high resistance, n BT151 for brx49,|
