This simple charger is good for 6V lead acid batteries.The main part of the circuit is the LM317 regulator IC that limits the output voltage based on R1 and R2 values. Note: If you need a more improve charger with current and voltage control, try to modify the automatic 12V charger circuit.
Electrical Engineering Stack Exchange is a question and answer site for electronics and electrical engineering professionals, students, and enthusiasts. Also, a circuit to charge the 12V 7Ah battery with full charge cut off so that I can connect these circuits so that there is no need to look after it after connecting everything like need to recharge the battery every day.
Automatically change over to battery so that the modem works on power outage with out disconnection. Sense the voltage of the battery with the ADC, making sure you scale the twelve volts down with a voltage divider as the Arduino will only handle an input of 5V on the inputs. What are you going to use for an input, as you may have to get a AC to 12V DC power supply?
Expanding up on this since my answer would generally be the same; many batteries have an integrated circuit board that will protect the battery from over charge and under-voltage lockout. Not the answer you're looking for?Browse other questions tagged transistors capacitor transformer diodes circuit-analysis or ask your own question.

I need a circuit will show the charge status during charging(i.e the chrger connected to battery).
The charger automatically turns the supply off when battery reaches its full charge voltage. Or better use another browser which respects html and css standards - Mozilla Firefox, Opera, Google Chrome, Safari etc.
Then Gives 10v to this circuit using adjustable power supply and adjust VR2 to yellow led comes on.
It has a led indicator that turns on when the battery is fully charge thus help you when are you going to remove the battery from the charger. I can't link you because I do not know what type of battery, I can assume lead acid though, which is good as these are fairly common circuits. Just because the battery can supply larger currents won't cause harm unless the modem is defective. Your post helped me in my college assignment, If you can provide me more details please email me. When it is conected to charge then the charger voltage (like 14v) appear on circuit terminal so it will show that voltage. Our website contains Free Collection of Electronics Circuits, PIC microcontroller projects, diagrams, tutorials, cad and PCB design software, vintage vacuum tube archives, hobby designs, datasheets and many schematics.


Without Q1, the circuit still works the way it is designed but there is a chance that it will take some time before it stops the charging, thus might damage your battery. Most of the chargers are designed to switch over to battery power if no alternative source is supplied.
You can get prebuilt units from Amazon, or individual IC chips from a supplier like digikey depending on your EE knowledge.
For your transformer, convert it in full bridge type, meaning you need two more diodes (4 pcs of diode D1 in total).
It will ensure also that the charger will not turn off unless the battery voltage reaches the full charge state.. What should be the values of R1 & R2 or what are the required adjustments to this circuit in order to charge my battery.
