Useful Functions: Start-up Test: Start-up voltage, start-up time and boltage are all available for the start-up test to check if it is normal. Battery Test: You can test the health (SOH) and state of charge (SOC), including test value, battery voltage and internal voltage. Charging Test: To test whether the charging system is normal and you can rest assured to use the battery, you can access the charging test to test the charged voltage, no-load voltage, load ripple and boltage. Battery Test Result: 1. Good Battery: The battery is in good condition, and you can rest assured to use it; 2. Good, Recharge: It is a good low current battery, and please recharge it before next use; 3. Replace: The battery is almost or already broken, and you should replace the battery, or there will be potential danger; 4. Bad Cell, Replace: The battery is broken or damaged internally or has short circuit, and it is time to replace the battery; 5. Charge-Retest: The unstable battery should be recharged and re-examined to avoid error. If the same test result appears again, the battery is considered damaged, replace the battery.
