    Anyone familiar with what Milliamp drain is on 2015 Pri two 12V batt when hatch is open?
    Battery is only a year or so old, no lights on, no other doors open. EVERYTHING imaginable is off, but battery died in two days with hatch open. Grrrrr.... death of first battery my bad.. left a door ajartoo many times in garage. I have a kit of all LED bulbs to replace the STUPID halogen bulbs. !!... why Toyota wasn't smart enough to put all LED bulbs in interior in 2015...
    a couple hundred $ batt teaches you real quick.
    Considering (for fun) a smart shunt for monitoring while nearby. Victron makes a cool one.
    Anyone have a problem with that?…
    Thanks.

    Yes. It's about 700 mA, which is sufficient to discharge a good battery in two or three days.
