    Diagnosing a Ti-84 Plus CE with a Defective Battery

    To help avoid battery issues in the future, here are a few simple tips to extend the lifespan of your Ti-84 Plus CE rechargeable batteries:

    1. Store calculators properly: Keep the calculators in a cool, dry place—ideally at room temperature—when not in use.
    2. Charge periodically: Recharge your calculators' batteries at least every 2-3 weeks, even if they’re not being used. Never let the battery fully deplete!
    3. Remove batteries for long-term storage: If your calculators will be stored for more than three months (aka Summer Vacation), remove the batteries beforehand, especially if they won’t be charged during this time.
