Yes. The battery tester will display SOC (State of Charge) as a percentage of the battery's rated capacity, which is a state measurement that assesses potential energy.

Please note that a good SOC (State of Charge) does not necessarily mean the battery is in good condition. You need to refer to the actual CCA value and internal resistance of the battery for further analysis.

1.11. I would like to understand the working principle and judgment logic of battery testing. Can you provide some basic knowledge on this?

Here are some basic points about battery testing that I can share with you:

1. The battery test results mainly refer to SOH and battery voltage. SOH stands for State of Health, which includes battery capacity, health, and performance status. SOH≧80% is good, 60%-80% is average, 45%-60% requires attention, and <45% suggests replacement.
2. The internal resistance of the battery; for a 12V battery, it is generally below 10 milliohms, the lower the better. If it exceeds 15 milliohms, the battery is likely damaged.
3. When the battery capacity drops to 80% of its original rated capacity, the capacity may decline sharply. At this point, although the battery may still provide some energy, it could fail at any time.
4. The traditional method of determining battery health is the discharge method, which tests the actual capacity of the battery by discharging it, thereby determining the battery's health status.

2. Download and Upgrade

1.8. Performing Battery Testing on Devices Not Connected to the APP, the Customer's CCA and Battery Capacity are 102 or 109. However, our device adjusts the value in increments of five. How should such values be tested?

First, the battery tester itself cannot 100% accurately assess the overall health and lifespan of the battery. Battery performance is closely related to the environment, usage history, aging patterns, and other factors. The instrument's measurement often only provides a static snapshot, so in the current situation, you only need to choose the value closest to the customer's parameter data.

1.9. Battery Testing Device: Is There an Option to Choose Between In-Vehicle or Out-of-Vehicle Battery Testing?

1. In-Vehicle Testing Refers to:

• Battery Testing: In-vehicle testing generally refers to the testing scenario where the battery is installed in the vehicle and connected to the vehicle's electrical system. Vehicle noise impact is considered. The battery's state is tested, including its ability to start the vehicle, capacity state, and charge state.
• Starter Testing: The health of the starter is tested.
• Alternator Testing: The health of the alternator is tested.

2. Out-of-Vehicle Testing Refers to: Out-of-vehicle testing generally refers to the testing scenario where the battery is disconnected from the vehicle's electrical system. Noise impact is not considered. The battery's state is tested, including its ability to start the vehicle, capacity state, and charge state.

• Battery testing devices do not have an option to choose between in-vehicle or out-of-vehicle testing; they directly enter the testing phase. This is because the difference between the two is not significant.

1.10. Reasons for Significant Differences in Two Battery Test Results

Follow these troubleshooting steps:

1. The battery is not correctly connected; do not use jumper cables or leads, but directly clamp onto the battery's positive and negative terminals.
2. There is rust on the battery terminals; it is recommended to clean them and retry.
3. The measurement interval is long, and the battery voltage changes, leading to different test results.
4. It is recommended to test in a fully charged state for results closest to the actual value.

1.11. Why Does the Test Result Show 70% Health but Indicate a Bad Battery That Needs Replacement?

The health percentage is one of the parameters of the battery test results, along with CCA, internal resistance, charge state, etc.

The health percentage and the test result "bad battery, please replace" are not directly related. It is normal for a health percentage of 80% to prompt a replacement, including with authoritative battery testers like Midtronics. Please base your decision on the final judgment result; the health percentage can be used as one of the reference data.

1.12. Possible Reasons Why Using a BT Series Battery Tester on a New Battery Shows "Bad Battery, Replace"

1. The battery is not correctly connected; do not use jumper cables or leads, but directly clamp onto the battery's positive and negative terminals.
2. There is corrosion on the battery terminals; it is recommended to clean them and reconnect for testing.
3. The battery is in a low-temperature environment of 0°C or below, causing the internal chemical materials to become less active, leading to increased cold cranking amperage (CCA) and internal resistance, resulting in measurement deviations.
4. The new battery has been stored for too long without timely maintenance, causing the battery voltage to be too low. It is recommended to fully charge the battery and let it sit for a few hours before testing.
5. Long-term storage without regular charging maintenance has caused severe battery aging, significantly reducing charge and discharge performance, resulting in poor actual health.
6. Device malfunction; it is recommended to use another authoritative brand tester for comparison and confirmation.

1.13. Possible Reasons Why a BT Series Battery Tester Shows a Battery Health (SOH) of 80% and the Test Result Indicates "Bad Battery, Replace"

Battery health (SOH) is one of the parameters of the battery test results, which also include cold cranking amperage (CCA), internal resistance, charge state (SOC), voltage, etc. The tester calculates the test result based on the values of all test items. Battery health (SOH) alone cannot determine the quality of the battery.

1.14. Reasons Why Using a BT Series Product for Battery Testing Prompts "Battery Voltage Too High" and Cannot Test

After the battery is fully charged, the voltage can reach 14V or even higher. At this time, the voltage is actually floating voltage, which can affect the battery test results. Therefore, the software will prompt "battery voltage too high" and not allow testing. It is recommended to let the battery sit for a while or turn on the vehicle's electrical appliances to let the battery voltage drop below 13V before testing.

1.15. When Using a New Mobile App to Test a New Battery, the System Prompts to Replace the Battery, but All Parameters Show Normal

If the current parameter test results are normal, it is recommended not to test immediately after charging or discharging. It is recommended to fully charge the battery and let it sit overnight before testing.

1.16. When Sharing a BT Mobile Pros Battery Test Report on the Diagnostic Tablet, It Prompts "Email Sending Failed"

To share the test report, you need to log in to the BT Mobile Pros account first; otherwise, sharing is not possible.

1.17. Different Standards Have Different Test Methods and Performance Requirements for Batteries

This is mainly reflected in:

1. Temperature requirements: For example, CCA testing is done in low-temperature environments, while MCA is used in warmer environments.
2. Test focus: Some standards focus on the battery's starting current (such as SAE, BCI, EN), while others focus on battery safety, charging efficiency, and lifespan (such as IEC).
3. Usage regions and application fields: Different standards have different regional and targeted characteristics. For example, SAE is mainly in North America, JIS in Japan, DIN in Germany, and IEC is an international standard. When selecting a test standard, consider the battery's application environment and market requirements to ensure the accuracy of the test results.

1.18. Why Are BT Series Battery Tester Readings Inconsistent, and How to Obtain More Accurate Readings?

Our battery testers mainly use discharge testing (except for BT20). Since charging and discharging are chemical reactions, the results may vary depending on the test time. To obtain the most accurate readings, we recommend the following:

1. Ensure the battery terminals are well connected and clear any corrosion or rust before testing.
2. If performing multiple tests, wait at least one minute between each test, then disconnect the tester from the battery.
3. If the vehicle has recently been driven, turn on the headlights or radio for about 30 seconds to slightly discharge the battery, then turn them off and wait 30 seconds before testing.

*Be sure to test with the vehicle's ignition turned off to avoid interference. Consider temperature differences during testing, as the chemical reactions in the battery are affected by temperature. Ensure you are using a reputable battery brand to avoid inaccurate results due to poor battery quality.
