    What is State of Health (SoH)?

    Current battery capacity vs when it was new — a health score.

    SoH measures how much capacity the battery retains compared to when it was new. A new battery has 100% SoH. After 8 years of typical use, a battery may show 80-85% SoH, meaning it holds 80-85% of original range. Most warranties kick in if SoH drops below 70%.
