I have a 94 Q. I stored my Q this winter, just after buying it. I check the battery every 2 weeks or so, put my battery charger on it and it is run down every time I do this. I have read before in this forum other questions pertaining to this topic, but I guess I didn't pay enough attention to it because at the time it didn't concern me. Now I can't find the forum, anyway would someone please respond. My question is, is there something running my battery down, that I can fix, or is this something the Q does?? I also have a Tundra stored and the battery in it is still at full charge since Nov. Thanks for help!!! Wayne

Read your manual concerning the proceedure for pulling the storage fuse.

The ecu, tcu, body module, alarm, and radio memory draws around 120 milliamperes in standby x 24 hours = 2.88 amp/hrs per day.

Brand new correct batteries might allow 30 days used ones half that long.
