    Hello guys, sometimes my prius battery indicator will go down to 1 bar. Ive looked online, and the lowest Ive ever seen it online is 2 bars which seems normal (40% SoC). Why does mine go down to 1?

    Is it the original battery? Mine did that when it got weak. It surprised me!
    And it would quickly charge fully, almost to the 2 tabs that indicate the terminals.

    Time for a Sodium Ion Battery Pack!
