hey guys, i don't smoke so i don't know if the cigarette jack still drains the battery after the car is off. i recently lost the lighter itself somewhere when using the jack to charge a device. so the car has an empty hole there where the lighter is supposed to be. today my battery died. i haven't driven my car in 2 weeks and i haven't driven it lately without the device plugged in. this could be a coincidence (old battery) or it could mean that i really should find the lighter. can you let me know if the absence of a lighter may have caused this? thank you.
