All cars have a peak point where they need to be recharged to work fine. To know the battery status of the car, you have to check it through the DC AMP meter.
Exactly, how to read a battery charger AMP meter 2 sides (positive & negative)? The procedure is a bit tricky as you have to get familiar with parts as well as the meaning of numbers to read the whole data better.
Let me show you the right way of reading the battery charger amp meter!
Exactly How To Read A Battery Charger AMP Meter 2 Sides.
To know the charging status of the battery, you have to gather the battery charger and digital amp meter. Next, follow the given steps.
Step 1: Connect the Battery Charger.
- Open the car hood and locate the battery.
- Take out the battery negative terminal and then the positive terminal. Wear safety equipment to protect yourself from burning before doing anything.
- Remove the battery charger outside and place it on a table.
- Place the red cable of the battery charger on the positive side (red) of the AMP meter.
- Insert the black cable of the battery charger to the negative side (black) of the AMP meter. During the procedure, you’ll see a slight spark. So, it is wise to attach it from a good distance.
Step 2: Turn On The Charger.
- Switch the battery charger on.
- Wait for a minute like this.
Step 3: Understand The AMP Meter Settings.
I’ll mention all the settings in a brief manner so that a beginner can understand the main function in order to read later.
- Charge Value (AMP): It indicates the flow of AMPs that the battery gets when charging. The number it contains are 0, 2, 4, 6, 8, 10, & 12.
- Charge Percentage (%): It indicates the battery status of the car battery. You’ll mostly see 100, 75, 50, and 0 numbers in this section.
- Indicator Needle: It is mostly yellow and moves from left to right in order to signal the exact info of battery status. So, if the battery charger reads 0 AMPs, the needle will move to the right side and slowly move toward left side indicating the full charge status.
- Green & Red Areas: The green areas literally indicate the 2A charging rate (showing the power flowing to the 2A setting). Oppositely, the red areas indicate the 12A charging rate (showing the current shifting to the battery through the charger).
- Battery Type Selector: It’s right below the LED screen of the DC AMP meter. This contains 2 settings which are: AGM and Standard. It also has a slider to set the setting based on your battery type.
- Charge Rate Selector: This contains 3 settings which are: 2A (Trickle Charge), 10A (Fast Charge), and 50A (Engine Start). With this option, you can select the charge rate which will send the battery to power up based on the speed of charging.
Step 4: Set The Battery Type & Charger Rate Selectors.
- Select the battery type selector option either AGM or Standard depending on your battery.
- Move the slider to set the charger rate selector.
Step 5: Plug The Battery Charger Into AMP Meter.
- Connect the 2 cables plug (charger and meter) tightly.
- Check the DC AMP meter screen to ensure if it’s connected or not. The needle will move slightly to indicate it’s working fine.
Step 6: Read The Battery Charger.
Look closely at the needle which will move to the right side and then come to the left gradually.
- If the needle is between the 0 to 2 charge values, that is exactly what a car battery charger should read when fully charged which also means 100%.
- If it’s between 4 to 6 charge values, it means the battery is close to 100%.
- If the needle stays in between 10 to 12 charge values, then it indicates the battery is below 25%.
Tip: After reading the battery charger through the AMP meter, be sure to charge if you find the battery below 25%.
Conclusion
Understanding the whole thing is what makes the reading of the AMP meter easy. Now that you know how to read a battery charger AMP meter 2 sides, it’s your turn to test it and see the condition of your car battery status.
This reading technique will help you to locate any errors easily. I really hope this guide is able to serve the purpose well with all the necessary data and handy tricks.
Have A Wonderful Day!
