Parasitic Draw

- Inspect and record the current reading.
- Note the battery Reserve Capacity (Amp Hour rating). Refer to Battery Usage.

1. Divide the reserve capacity by 4 Amp hour rating by 2.4.
2. Compare this to the multimeter milliamp reading taken in the previous step. The parasitic current drain should not exceed this number. Example: If a battery has a reserve capacity of 100 minutes, (60 A/H) the current drain should not exceed 25 mA. Electrical Drain/Parasitic Load Test
