They may be passive pickups with covers. Just because the pickups have covers doesn't mean they are active.

Does the guitar work without battery? If yes, then they are passive pickups. If there is no battery slot, they are most likely not active.

EMG also makes passive pickups that look exactly the same as their active pickups:

Have you checked in the electronics cavity? Sometimes batteries are just in there with the pots and pickup switch.
