You’ll want to make sure that the charger you choose is compatible with the type of battery you have. For example, if you have a lead-acid battery, you’ll need a lead-acid compatible charger.

Yes, you can charge a 12V 12Ah battery with a car charger. The process is simple and straightforward. All you need is a car charger that is rated for the voltage and amperage of your battery. battery is in the charger using a red LED.25-50% using a blue LED (red LED goes out)55-75% using a yellow LED (LED red, blue outages)75-100% using a green LED (LED red, blue, yellow outages) next to Battery Charger Circuit 12 V I want to use the 5 LED lights as follows:0-25% using a red LED25-50% using orange LED (red LED goes out)50-75% using a yellow LED (LED red, orange outages)75-100% using a blue LED (Led red, orange, yellow outages)more than 100% using the green LED (LED red, orange, yellow, blue outages). On average, a 100-watt solar panel will take about three hours to charge the battery. However, it’s important to know that this does not mean all of the energy from the solar panel will be used to charge the battery. Will a 5-watt solar panel charge a 12v battery? Commonly used in Alarm Systems, Emergency Lighting,Torches, UPS systems and other electrical systems Basically the main function of this IC is voltage control and can also be wired for controlling currents through some simple modifications.As soon as the connected battery is charged fully, the potential at the inverting input of the opamp becomes higher than the set voltage at non-inverting input of the IC. This instantly switches the output of the opamp to logic low."

First of all let me say thank you for your fast replying. I will try your suggestions. before that i need to confirm the changes you mentioned. I will attach an image consisting your suggestions. So please confirm the changes in the circuit. -vinod chandran The connected ammeter is used for monitoring the charge condition of the battery. Once the ammeter shows zero voltage, the battery may be detached from the charger for the intended use. Circuit Diagram #1 Parts List Adjust the base transistor pot such that the LED just starts to glow at 14V. Do these adjustents without the battery connected at the output. The second circuit is also good but is not automatic....is current controlled, though. Let me know your thoughts. Thanks, Swagatam Additionally, make sure to disconnect the charger once the charging process is complete. Leaving it connected could damage both your battery and charger over time. How to Charge 12V Battery Without Charger? Unfortunately, many YouTube videos about making SLA battery chargers do not explain those critical terms. The real intention of some YouTubers is not to share valuable knowledge, but to duplicate other people’s ideas and shoot videos without knowing anything technically – only for monetary gains, and/or to support their PCB sponsors!
Calibration of 12v, 7Ah Smart Battery Charger with PCB Diagram
The constant voltage charge method applies a constant voltage to the battery and limits the initial charge current. Here, a DC voltage between 2.3V per cell (standby/float) and 2.45V per cell (fast) is applied to the terminals of the battery. Depending on the state of charge (SoC), the cell may temporarily be lower after discharge than the applied voltage. After some time, however, it should level off. Charge controller: A charge controller acts as a regulator, preventing overcharging and optimizing the charging process. First off note that SLA batteries may be charged through different charging techniques, to obtain maximum battery service life and capacity, along with acceptable recharge time and economy, constant voltage-current limited charging is the best method. This charging method can be used for both cyclic and standby/float applications. AGM (Absorbed Glass Mat) refers to a specific type of SLA/VRLA where the electrolyte is absorbed into separators between the plates consisting of sponge-like fine glass fiber mats. AGM batteries are extremely resistant to vibration, are totally sealed, non-spillable, and maintenance-free. AGM offers better cycling performance, minimal gassing, and acid leakage when compared with conventional lead-acid batteries. The ADJ pin of the IC is fixed to the junction of the resistor R1 and the variable resistor R2. R2 can be fine set for aligning the final output voltage with the battery.
