Is this a normal value? Or should I further investigate what's using power when the car is shut off?

BR,

If you have not already done so, I suggest you check the fluid level in the battery. Also, clean the battery posts.

Also, you may want to have the battery load tested to see if it has a weak cell.

My 9 year old battery seems to get lazy every few months, so, I zap it with a battery charger for a few hours and that seems to perk it up for a few months. I only drive my car for about a dozen miles 2-3 times a week.
