Some people might not know that lead-acid batteries are one of the world’s most common battery types. Lead acid (or flooded cell) batteries have been around for over a century, and they can be found in everything from cars to power plants. With so many applications, it is no wonder why AGM Batteries look like such an improvement! Unlike traditional lead acid cells which contain sulfuric acid inside their metal cases, these new sealed units don’t need any maintenance or fluid refills – this makes them safer than even regular gas powered vehicles!
AGM Multimeter Test
Step 1
Turn on the Multimeter and choose to measure voltage. You will see a dial with numbers ranging from 0-1999mV, just turn it until you reach Voltage in order to set your desired measurement unit.
The multimeter is an electronic device that measures electric potential difference (or voltage) between two points of a circuit by using its voltmeter function. The meter has three main functions: AC Volts for measuring alternating current; DC Volts for measuring direct currents such as battery charges or power lines; and Resistance Measurement which can be used when troubleshooting electronics like resistors, LEDs etc., but also circuits containing capacitors/inductors or other components having nonlinear behavior under sinusoidal excitation
Step 2
Place the sensor on the end of a red wire from your meter onto one terminal and then place it at another to see if there is any voltage. For AGM batteries, you should have 13 volts when they are fully charged. This will be slightly higher than 12 so that people can measure for themselves with some accuracy
AGM load test
Step 1
The AGM battery is a versatile power source which can be used for many purposes. One of its best features, the cold cranking amp rating (CCA), tells you how powerful it is and if it’s suitable to use in your vehicle or on something like your golf cart. The CCA number indicates amperes; so an example with 70 written would mean that this unit has capabilities up to 350 amps!
Step 2
Divide the CCA or Ah by 2 using a calculator. For example, if the label reads 70/CCA 8800mAH battery, divide this number to get 3500mA for your load-test meter reading. If your battery is charged and in good condition then you should see this figure on it when tested with an external power supply of 12V DC 1000 ma
Step 3
You will measure the strength of your battery by using a load tester. Attach alligator clips to each end and attach them accordingly according to “+” or “-” terminals on the battery, then turn it on for 10 seconds before reading its display
Step 4
Press the Load Test Start Button. Watch as your battery life drops to its lowest point, and then increase 10%. Check out how long you can go until all of a sudden there is no juice left at all! You’ll want to make sure that when this happens (and if you are not plugged in), charging power should be available right away so your phone will never die on the job again.
