New Battery And State Inspection Question, Please

Hello,
Had a new battery installed yesterday.
Today, I went for a state inspection sticker, and they told me that they couldn't do the inspection due to the new battery.
Apparently, all the self-checks, etc. that the car does is not operable when a new battery is installed. Said it "takes a few weeks".
Don't really understand why.
Question: is this a matter of time, or mileage, from when the battery is installed ?
If mileage, approximately how many for the car and the battery to play nicely together ?
Etc. ?
Car is a 2010 Hyundai Elantra.
Much thanks, Bob

Has nothing to do with the battery itself.
When the battery was changed it erased the memory in the computer that controls the car. That memory stores the results of a bunch of self tests that the computer does at every start up as well as some that are done when a certain drive cycle is completed.
As the tests are cone and if they are OK a flag called a "monitor" gets set. Usually you are allowed to have one monitor that hasn't run, that is because some of the EVAP tests take a while to run.
When you took it in the computer they plugged in told them that you had multiple monitors that hadn't run, and that means no inspection.

Thanks for replies. Much appreciated.
Retired: Don't understand the page 5 graphyou suggested Could you explain it, please ?
And, the basic question:
Approx. how many miles, or is it ignition turn-ons, or,,,? does it usually take ?
Thanks, Bob -------------------------------------------------------------

The graph is meant to show the speeds and times you need to drive to reset the monitors.
Starting with 5 minutes of Idling in Park, then take 15 seconds to accelerate to 50 mph, then hold 50mph for 8 minutes, the take 15 seconds to decelerate (no braking) back to Idling for 15 minutes, and so on......
This sequence is specific to Hyundai. Other makes have different cycles.
If doing the specific cycle is a problem, then several days (or weeks) of normal driving with similar speed changes etc will usually reset all the monitors.
It is not a set # of miles, or ign on/offs, it is the cycles as described.

Every model is different and each test is different.
For instance the "drive cycle" for the O2 sensors runs as a constant test.
An EVAP test on the other hand can be a LONG time item. It looks at how full the gas tank is, what the engine temperature is, what the ambient temperature is, the engine speed and load, how long the engine has been running, vehicle speed and transmission status. Each item has a window that all need to match the testing criteria before the test will run.
The chart posted is the drive cycle that will set the monitors on your vehicle. BUT, even following that drive cycle may not get the EVAP monitor to set. Which is why most states allow one or two monitors to be open and they will still inspect the vehicle.

On many cars, disconnecting the battery clears all the logs in the ECU, and they want to see some ECU logs.... plenty of error flags won't be set until there is a certain amount of log in the buffer, too.
How much you'll have to drive depends on your car and state. You do mention you have a 2010 Elantra, but not where you are located. --scott
