Parasitic Draw

- Take the reading in milliamps.
- Note the battery reserve capacity. Refer to Battery Usage.

- Divide the number by 4. Example: 90/4=22.5
- Compare this to the ammeter reading.
- The current drain in milliamps should not exceed this number.
- Example: if a battery has a reserve capacity of 90 minutes, the current drain should not exceed 22 milliamps.
