- 12v 7ah Battery Charger Circuit
Simple 12 volt battery charger circuit diagram designed by using few easily available components, and this circuit is suitable for different types of batteries needs 12 Volt. You can use this circuit to charge 12V SLA battery or 12V Gel cell battery and so on. This circuit is designed to provide charging current upto 3 amps and this circuit don’t have reverse polarity protection or over current protection so kindly test this circuit before stepping into battery charging.
For safe working and to avoid overcharging of battery, absorption voltage is selected as 14.1V and floating voltage is selected as 13.6V. These values are to be set as specified by the battery manufacturer. 12V battery charger circuit Fig1: 12V battery charger circuit. Circuit diagram of the 12V battery absorb and float charger is shown in Fig. A good designed circuit of a Alkaline battery charger. The interesting thing of this circuit is that it uses a led that will show the charge of battery by blinking, when you connect a totally discharged battery the LED blink faster but when the battery charging process starts the LED blinking speed will dicrease slowly and completely stop when the battery will fully charged. Here is the circuit diagram of a simple and straight forward 12 V battery charger circuit with diagram. This circuit can be used to charge all type of 12V rechargeable batteries including car batteries. The circuit is nothing but a 12V DC power supply with an ammeter for monitoring the charging current.

12v 7ah Battery Charger Circuit Diagram Pdf System
The project Arduino Controlled 12V battery charger circuit is advance version of previous posted project “12V, 7Ah Smart Battery Charger with PCB Diagram”. This charger also has the features of bulk stage charging and float stage charging as in previous circuit. Silent features of Arduino Controlled 12V battery. So we want to show you a simple circuit for the charger when the battery is fully charged, the charging automatically stopping, this is a circuit of the auto cut off battery charger, it has only:-one NPN transistor such as c1815 for controlling the charging, - relay for cutting off this current path through the battery after fully charged.
This Simple 12 volt Battery Charger Circuit Diagram gives you a outline design for the general battery charger and you can add additional features to this circuit like reverse polarity protection by placing a diode at the output. (Diode anode to output positive supply and diode cathode as output positive terminal) and over current protection setup using transistors. The following charger circuit just a Raw prototype to give 12 Volt output to battery.
Circuit Diagram
12v 7ah Battery Charger Circuit Diagram Pdf Diagram
Components Required
- Step down transformer (0-14V AC / 3 Amps) – Choose depends on your requirements.
- Bridge Rectifier module BR1010
- Capacitors 0.01µF, 100µF/25V each one
- Resistor 1KΩ (Use 0.25W for normal LED)
- LED
Construction & Working
Use Required ampere Step down transformer for your target battery, here we have used 0-14V AC / 3 Amps Step down transformer and for AC to DC rectification we have used Bridge Rectifier module BR1010 which gives High efficient DC supply with high Current rating.
BR1010
This Bridge Rectifier module will have four terminals, two for AC supply input noted with sign wave and two terminals for DC output noted with positive and negative sign.
C1 and C2 capacitors are performing as filter in this circuit then LED indicates the presence of DC power supply at the output. Connect the target Battery at the output to get charged.
