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 dont have reverse polarity protection or over current protection so kindly test this circuit before stepping into battery charging.The following charger circuit just a Raw prototype to give 12 Volt output to battery.
Bridge Rectifier module BR1010 Capacitors 0.01F, 100F25V each one Resistor 1K (Use 0.25W for normal LED) LED.

It tapers off to 4A at 13.5V, 3A at 14.0V, 2A at 14.5V and 0A at 15.0V. 12V Battery Charger Schematic Diagram Plus Q1S EmitterR1 effectively sets the current through Q1 the voltage across this resistor plus Q1s emitter-base voltage is equal to the voltage across D1-D3. Assuming 0.7V across each diode and across Q1s base-emitter junction, the current through R1 is approximately 1.40.34 4.1A. IC ensures that Q1 (and thus the constant current source) is turned on. It allows enough current to flow through the regulator so that Q1 is fully on for battery voltages up to about 13.5V. Decreasing the value of R2 effectively increases the final battery voltage by raising the current cutoff point. 12V Battery Charger Schematic Diagram Series With OneConversely, a diode in series with one of the battery leads will reduce the fully-charged voltage by about 0.7V. Well explained. I have seen another advanced level circuit for this project in the post. No doubt about it. As a test engineer, I follow this site about all the new updates and these are excellent. Last year my Mercedes showed some major technical issue while commuting and I took it to the most trusted and fully experienced repairing center in South Florida and they give the expert service with a very reasonable price. There are many ways where one can charge the battery properly. This transistor is not available in any electronic store and the data sheet can not found. Also what i need to change to use other color Leds (3.10V 20mA, 2.10V 20mA. I am looking for someone that has actually got it working as well. When the monitor first powers up, you should see a message on the screen even when no computer is plugged in. If you dont see anything then it is likely that the monitor is bad. If you see the power-up message but nothing from the computer then you should try different cables (which you say you did) or it could be a setting on. ![]() He wants to use Low Frequencies for voice communication, presumably for underground or underwater applications. At low frequencies, the audio bandwidth is severely restricted, which normally precludes the use of voice communication at such low frequencies, especially if the available frequency allocation is narrow. If there was a way (digital or other) to down-convert the voice modulation frequencies from a normal communication range of 300-3000Hz to say 30-300Hz, the Low Frequency carrier could then be successfuly modulated with this down-converted audio, then upconverted by the receive station. What do you see when you touch the tip of your scope probe to the same point the probe ground is connected to When using two scope probes and AminusB differential mode, connect the two probe ground leads to each other and not to the PCB. When you touch both probe tips to the same point, you should see zero signal on the scope. You could try measuring the DC offset using a battery-powered digital voltmeter. If possible, get one that allows you to set the temperature in the range you desire.
