Lead Acid Battery Tester Arduino

If you re testing an automobile battery take the vehicle for a 20 minute drive then shut off the engine for 4 hours for other types of lead acid batteries charge them all the way before letting them rest for 4 hours.

Lead acid battery tester arduino.

Charge the battery fully then let it rest for 4 hours. Because of measurement offset to achieve better voltage measurement resolution only voltages from 10 1 v to 14 7 v can be measured which means any voltage below 10 1 volt will read 10 1 volt. While it takes a bit of time this process of charging and then resting the battery gives you the most accurate. What i did.

The ar bareduino does. Only 12 volts lead acid batteries up to 200ah can be discharge. Only 12 volts lead acid batteries up to 200ah can be discharge. Because of measurement offset to achieve better voltage measurement resolution only voltages from 10 1 v to 14 7 v can be measured which means any voltage below 10 1 volt will read 10 1 volt.

Right now i can test lipo liion life and lead acid batteries. In this post we are going learn how to make a smart automatic lead acid battery charger which can charge 6v and 12v battery types with capacity ranging from 4 5ah to 15ah. The main changes i did are the 20x4 lcd rather than buying a nokia 5110 that the original author used. As for software i have an lcd connected to the arduino as well as a few pushbuttons.

Besides a 12 volt lead acid battery that reads 10 volt is practically dead. With that in mind here s my derivative of this tester. Since my supply of cells will be primarily used stock from various recycle streams i needed to come up with the tools to test each cell. Besides a 12 volt lead acid battery that reads 10 volt is practically dead.

Lead acid battery capacity tester updated a 12 v lead acid battery is discharged at a constant current programmable for a period of time to get terminal voltage vs time curve.

Out of many different types of batteries available lead acid batteries ni cd batteries and ni mh batteries are not suitable as they either weigh more or cannot provide the current required for our application this leaves us with the lithium ion batteries which can provide high current while keeping the weight low and size compact. Now the resistor r2 is a digital 10k potentiometer mcp4131 the resistance can be programmed through spi communication.

I can basically test any battery under 14v so i ll be adding a few more types to the software in the near future. The proposed lead acid battery charger is feature rich and packed with several.
