dead battery on new XC70

I recently experienced a dead battery on my 2004 XC70. This happened
first thing in the morning after being parked in my driveway
overnight. Battery seemed to be completely dead - no dome lights, no
power seat adjustment, no click when attempting to start the vehicle.
The only difference on this night from the other 30 or so days that I
have owned the car is that the key was inadvertently left in the
ignition over night. Ignition was in the OFF position and no doors
were left open. I was able to start the car after charging the
battery for approx one hour and everything seems normal since then.
Any ideas what caused this?

 

When you put the key into the ignition, it turns on the interior lights
until you turn the key to start the car. The interior lights run the
battery down.

 

That, and a lot of new cars will leave the interior lights on until you pull
the key out after you are done putting it in park and turning off the
ignition... Either way you are screwed for the lights being left on, teaches
you to not leave the keys in the ignition.... You must really trust your
neighbourhood to do something like that (unless it's in a garage, but then
you are just asking for the car to be stolen).

 

Give the guy a break.

He did not mention that the lights were on or left on.

Leaving the key in the ign after getting out will not turn the dome light
on.

Putting the key in the ign, the dome lights will go out after about 30
seconds

if the car is not started.

Besides the queation was not, Will my car be stolen if I leave the key in
the ignition.

The dome lights were not on, and I do not buy the argument that they
will stay on if the key is left in the ignition.

Besides, even if they WERE on, we're talking about a one amp load for
approximately 12 hours against a battery that should have a capacity
of 60-70 amp-hours. Something abnormal happened and I am trying to
find out what it was.

 

FWIW, our relatively new 2002 V70 T5 also suffered a dead battery.
Initially, I thought I did not close the tail gate completely when I visited
the car the evening before. In the AM, it was dead. Got a jump start and
went about my business only to have it go dead again after sitting over
night. Turns out that the battery had two dead cells. Luckily it was
replaced under warranty.
