    2010 Prius with 175k miles and still going with the original 12 v battery. In NJ kept inside a garage.
    Maybe it’s time to get a new one before I need to.

    I just tested this morning in vehicle signal mode and got 11.9.
    Then I turned the car on it steadily dropped to 11.3.
    Yeah time to replace
    I saw a deal at Napa online to pick up at store and with the 20% off coupon it will cost 167$US
    Thanks peeps!

    Yeah since you have framed it like that just replace before it goes bad after 4 - 6 years sounds the prudent thing to do.
    After turning the engine on the reading went to 13.7 only btw
