Default Dead battery - hatch wouldn't open after jump

My wife's 2010 RX350 wouldn't start this morning. My guess is that the battery drIned overnight with the back door ajar. After getting it started with a battery jump the rear hatch would not open by hand, the dash button or the key button. After driving and charging the battery the hatch would open. I'd this to be expected or an indication that perhaps the hatch has a fault?

Thanks!

It's likely due to the fact that the battery didn't have enough power to engage the motorized opening of the liftgate. You have a button in the glove box to disable the power hatch to open up at least manually if the dead battery reoccurs.

If the battery has never been replaced, you are due since typical lifespan is 5 years and seeing you live in Minnesota (MN) you'll need a fresh battery to ensure reliable starting power over this winter.
