Connect a battery to the circuit in series with a ammeter.Now adjust R5 to get the required charging current. Input to the IC must be at least 18V for getting proper charging voltage at the output .Take a look at the data sheet of LM 317 for better understanding.
Hi you can use for 8volt lead acid dry fit batteries (SMF) adjust output voltage for 9.6 to 10 volt, with R5 pot.
Did anyone have built one for 8v batteries or would have the specs for the resistance value for such. I am going to do a presentation about lead acid battery charger in one of my university courses, and your circuit really helps me, but i am not sure why you use BC 548, what direction of current flows around BC 548, and how does it works before and after battery fully charged.
Hi Chenwie a lead acid battery should be charged through constant voltage with the current limited 30% of the rated capacity of the battery or with limited 10% for 12 hours.
I am bit confused about the charging LED indication, Can you Please email me the connections for showing the Charging LED indicator which lights up when in the charging is in progress. I have a 12V 5AH conventional (the one with cell caps where you may add distilled water) lead acid battery. Further, what is the minimum required transformer voltage and current to get at least 15V rectified DC and 1.5A maximum charging current? Furthermore, can you provide me with a pictorial diagram of your battery charger circuit diagram? Finally, do you have any updates on how to add LED indicators in this battery charger circuit diagram? I have a Well Understanding of Lead Acid Batteries charging after reading certain circuits over the internet. This gives 1.2mA as the max current going into the collector of Q1, which will only be this high at the start when you charge a 100% flat battery. A search on the element14 website for through-hole LEDs with forward current If=1mA comes up with one 2mcd, three 3mcd and one 10mcd LED!
The circuit in Figure 1 shows how to build a USB-powered single-cell Li-Ion battery charger using National Semiconductor s LM3622 Li-Ion Battery Charger Controller.


This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors.
The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored.
It is a very useful bench test equipment for testing and finding out the frequency of various devices with unknown frequency such as oscillators, radio receivers, transmitters, function generators, crystals, etc. BA1404 HI-FI Stereo FM Transmitter broadcasts high quality stereo signal in 88MHz - 108MHz FM band. It is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors.
8-DIP machined IC socket allows to swap OPA2134 with many other dual opamp chips such as OPA2132, OPA2227, OPA2228, dual OPA132, OPA627, etc. It's breadboard compatible so it can be plugged into a breadboard for quick prototyping, and it has VCC & GND power pins available on both sides of PCB. That is why Deep Blue comes with a long-term battery capacity warranty: 9 years after commissioning, the batteries will still have 80 % of their original capacity, even if you use them every day.
These circuits are the best we have found in terms of accuracy, simplicity of operation, and cost.LM741 Operational Amplifier The LM741 is an operational amplifier. I need the charger circuit urgently because the charger of my e-bike has got damaged and I need to charge the batteries.
I was wondering if it would work with a 14AH SLA battery, and approximately how much time will it take to charge the battery completely if I increase the charging current with R5 POT. You can ask for a 224K capacitor instead, that’s the same value but in picofarad instead of microfarad.
It used this same LM317 charger ciruit and for a charge indicator they simply cut the circuit at the transistor’s collector and joined it up again using a red LED. 1.1), a high-power function must not draw more than 500 mA from the bus during normal operation. It can be connected to any type of stereo audio source such as iPod, Computer, Laptop, CD Player, Walkman, Television, Satellite Receiver, Tape Deck or other stereo system to transmit stereo sound with excellent clarity throughout your home, office, yard or camp ground. Unlike other ESR Meters that only measure ESR value this one measures capacitor's ESR value as well as its capacitance all at the same time. Headphone amplifier is small enough to fit in Altoids tin box, and thanks to low power consumption may be supplied from a single 9V battery. It's small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors. You can control lights, fans, AC system, computer, printer, amplifier, robots, garage door, security systems, motor-driven curtains, motorized window blinds, door locks, sprinklers, motorized projection screens and anything else you can think of.
Torqeedo developed the Johnson Controls high-voltage battery for use on water and for the special challenges of the marine industry. For your charging requirement of 12 volt 44AH battery a charger of 14.2 volt 12Amps is the requirement.
The LM3622 uses the 0.25 current-limit resistor R1 to set a 400 mA maximum charging current.
The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings.


Arduino Prototype uses all standard through-hole components for easy construction, two of which are hidden underneath IC socket. You can buy LM741 chips in the REUK Shop.LM741 High Voltage IndicatorThe circuit diagram shown above is configured to give a high voltage indication - LED turned on when the measured input voltage is above a certain level.
With flat battery it will start at 12 amps and it will start tapering of as the terminal voltage increases slowly.
This leaves a 100 mA surplus that can be used to supply USB control circuitry and other functions in the device. There are additional current restraints on a high-power USB function that apply during system start-up or when a device is initially connected to an active bus. USB IO Board is self-powered by USB port and can provide up to 500mA for electronic projects.
Board features 28-PIN DIP IC socket, user replaceable ATmega328 microcontroller flashed with Arduino bootloader, 16MHz crystal resonator and a reset switch. The 100KOhm variable resistor is used to manually configure the voltage over and above which the LED will light.If the reference voltage arriving at pin 2 of the LM741 is lower than the battery voltage arriving at pin 3 via the voltage divider created by the variable resistor, then the output from pin 6 of the LM741 will be low. Until a device is properly configured by the USB system, the device may not draw more than 100 mA from the bus. A case temperature than the FZT949 - butstill well within the accepted operationalspecification of the device.
In the above design, National Semiconductor s LM3525 USB power switch keeps the battery charger circuit isolated from the bus during start-up so that the charge current does not overload the bus.
Arduino sketches are uploaded through any USB-Serial adapter connected to 6-PIN ICSP female header. If the userprefers to run the case temperaturelower, than the FZT949 is the preferreddevice. When the port is properly enumerated, a USB control signal enables the LM3525 switch, connecting USB power (VBUS) to the charger circuit.
Board is supplied by 2-5V voltage and may be powered by a battery such as Lithium Ion cell, two AA cells, external power supply or USB power adapter. In addition to on-and-off switching, the LM3525 provides over-current and under-voltage protection to the design.
It is now configured to light up (or turn off) the LED at that exact voltage.If you do not have a variable voltage source - as is the case for most people - then you need to find a way to supply the desired reference voltage to the circuit for configuration. The universal battery charger using Lm317Here comes very simple idea is the universal battery charger circuit. The SCR1 (Silicon controlled rectifier) turn off, then not has a bias current path to ground.
Automatic Charger and Full charged indicator using LM317K-TL431This is circuit Automatic Charger and Full charged indicator. There is a tube LED show the work with use integrated number circuit LT431 perform check the level , voltage battery and systematically protect short circuit with IC LM317.
