Battery

Test

A WARNING
•   Battery fluid (electrolyte) contains sulfuric acid. It may cause severe burns if it gets on your skin or in your eyes. Wear protective clothing and a face shield.
- If electrolyte gets on your skin or clothes, rinse it off with water immediately.
- If electrolyte gets in your eyes, flush it out by splashing water in your eyes for at least 15 minutes; call a physician immediately.
•   A battery gives off hydrogen gas. If ignited, the hydrogen will explode and could crack the battery case and splatter acid on you. Keep sparks, flames, and cigarettes away from the battery.
•   Overcharging will raise the temperature of the electrolyte. This may force electrolyte to spray out of the battery vents. Follow the charger manufacturer's instructions and charge the battery at a proper rate.

If you're using a computerized battery tester, follow the test procedure provided with it. If you don't have a computerized tester, follow this conventional test procedure:
To get accurate results, the temperature of the electrolyte must be between 21 °C (70°F) and 38°C (100°F).
