### 🔧 How to Try It (Safely)

1. **Mix a Salt Solution**
Dissolve 1 tablespoon of salt in 1/4 cup of warm water. Stir until fully dissolved.

2. **Dip a Cotton Swab or Cloth**
Lightly dip your swab or cloth into the solution. It should be damp, not dripping.

3. **Wipe the Battery Terminals**
Gently rub the positive and negative ends of the battery with the saltwater-dampened swab.

4. **Let It Dry Completely**
Allow the battery to air dry completely before inserting it back into any device. This is crucial to avoid moisture damage.

5. **Test It**
Pop the battery back into your device. If you’re lucky, you might get several more minutes—or even hours—of use.
