You can get a Bluetooth ODB scanner for cheap on Amazon and it will tell you the exact battery life

    I have one already, but I haven't used it for 3 years, but from what I've heard that built in status isn't very precise.
    At the shop they run a test that takes 2 hours to determine the battery life, and you can have a more accurate test done that takes 24 hours. But that's a bit expensive.
