DUOYI Automotive Battery Life Internal Resistance Starting Performance Tester, DY225

1. Current load test value: approximately 20 A
2. Battery capacity detection range: 5Ah ~ 80Ah
3. Voltage: DC 19.99V (MAX)
4. Battery internal resistance range: 1.00 milliohm ~ 99.99 milliohm
5. LED status indicators:
- Battery condition: "green" (sufficient charge), "yellow" (low charge), "red" (battery needs replacement)
- Charging system: "green" (normal charging), "yellow" (charging abnormal)
6. Battery capacity preset: continuously adjustable within the range of 5-80Ah, with an increment of 5Ah per adjustment.
7. Test time: less than 10 seconds; recommended test interval is approximately 5 minutes.
8. Poor test clamp contact indication; reverse clamp connection protection; input overvoltage protection.
9. This instrument can quickly, easily, accurately, and reliably detect the no-load energy, load status, internal resistance, and charging system status of 6V and 12V lead-acid batteries.
10. The casing is made of sturdy ABS engineering material. The load heating simulation part is mounted with stainless steel perforated plates on the top and bottom, and a fan is configured to enhance heat dissipation, making the testing process more stable and reliable.
11. The test leads are made of thick pure copper test wires and are equipped with four-wire Kelvin test clamps for connection.
12. Test sample data is collected directly from the batterys output terminal to accurately reflect the batterys working state during operation, resulting in more accurate test results.
13. 4-wire internal resistance testing, 4-digit digital display for easy and clear reading.
14. The LED display is clear and the device is equipped with a protective cover that is not easily damaged by drops.
15. Dimensions: approximately 9.5 x 5.0 x 19 cm
16. Net Weight: approximately 860 grams
