Parasitic Draw

- Check and record the current reading.
- Note the battery reserve capacity, amp hour rating. Refer to Battery Usage (Non HP2) Battery Usage (HP2).
1. Divide the reserve capacity by 4, amp hour rating by 2.4.
2. Compare this to the multimeter milliampere 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.
