Great little gadget. Batteries don’t lasts as long now because of all the power equipment in modern cars. Day time running lights alone will shorten your battery life by at least a few months. Your alternator will have to work harder to provide extra power to your multifunction display, cell phone chargers and radar and other safety equipment.
You are absolutely correct on all of those points. But that's only half the story. Batteries are junk today, even when put in older vehicles that don't have all that malarkey. They'll only last 3-4 years, 5 if you're extremely lucky. I used to have car batteries last 9 years.
you should have used outside of vehicle test beacause it in not inside vehicle like under the seats, it is outside cause in is in the egine bay I think you should test again and see if you get different results
I see what you're getting at. What the test actually refers to is "Is the battery actually hooked up to the car or not?" Essentially, installed or not. That's what inside and outside means. It knows that the car is going to have electronics that could be drawing down the battery, and can apply correction to the readings. Best test is of course with the battery disconnected entirely. That's a lot of hassle to go through just for a reading.

You can also use a tester like that to test ups batteries. That's how I also use mine.
There's no real need to test them, they're always dead! That's been my experience.
