2009 IS250 current draw when sitting

So our 2009 IS250 had 194,000 miles on it going into our retirement season, so we picked up a 2015 Avalon for our daily driver (because I hated the seats in the ES350 of that year), and the IS has become my wife's car. But it doesn't get driven much: I run it on errands every 7-10 days. It doesn't seem to like this; I've gone through several batteries, and more than once, it's drained to zero. I'm surprised at the amount of spark I get when I connect the positive terminal. Other than the clock and some logic to stand by when you want to start it, where's all this current going? What's a normal draw for a sitting IS?

Thanks!

Ideal would be around 50ma but your car will be a little higher, always put the positive cable on first when installing a battery and last when taking one out.

Would be a good idea to get a battery minder.

Also check to see if the trunk light isn't switched on. On my 2006 IS, it's a switch that's easy to forget to turn off. But it would be a minor battery draw.
