Performing battery load test
WARNING: This page does not describe the selected car, but rather 27 other vehicles, including the 2002 Volkswagen Cabrio, 2001 Volkswagen Cabrio, 2000 Volkswagen Cabrio, 1999 Volkswagen Jetta, and 1999 Volkswagen Golf. However, it is still accessible from the selected car via links, so may be relevant.
- Switch ignition off.
- Read battery tester operating instructions.
- Connect tester cable clamps to battery terminals as described in tester operating instructions.
The clamps must make good contact with the battery terminals.
The load current to be applied varies according to battery capacity battery tester operating instructions or refer to table. Refer to BATTERY SPECIFICATION table.
- Perform battery load test as per battery tester operating instructions and compare test result with table.
A minimum voltage is the result of the load test according to battery capacity.
BATTERY SPECIFICATIONS
| Battery capacity | Low temperature test current | Load current | Minimum voltage (limit) |
|---|---|---|---|
| 36Ah | 175A | 100A | 10.0V |
| 40Ah-49Ah | 220A | 200A | 9.2V |
| 50Ah- 60Ah | 265A -280A | 200A | 9.4V |
| 61Ah- 80Ah | 300A -380A | 300A | 9.0V |
| 81Ah-110Ah | 380A-500A | 300A | 9.5V |
- If minimum voltage is not reached, replace battery.
Explanation of battery load check: Because of the high load on the battery during this test (high current flow) the battery voltage lowers. If the battery is OK, the voltage value only lowers to the minimum voltage.
If the battery is defective, or has a low charge, the battery voltage quickly drops below the minimum voltage.
This low voltage value remains over a long period and the voltage only increases again slowly after a successful test.
