Safety

Lead-acid batteries contain sulfuric acid which is a highly corrosive poison and will produce gasses when recharged and explode if ignited. This can hurt you! When working with batteries, you need to have plenty of ventilation, remove your jewelry, wear protective eyewear (safety glasses) and clothing, and exercise caution. Do not allow battery electrolyte to mix with salt water. Even small quantities of this combination will produce Chlorine gas that can kill you! Whenever possible follow the manufacturer’s instructions.
CAUTION/DANGER:

Lead-acid batteries contain a sulfuric acid electrolyte, which can be poisonous and is highly corrosive. Flooded Lead Acid batteries will produce gasses when discharging and re-charging which can explode!

Safety First

Although Poison Danger, Safety and Caution information is dispersed through the following information, we will list the basics below;

Danger of Exploding Batteries Batteries contain sulfuric acid and they produce explosive mixtures of hydrogen and oxygen. Because self-discharge action generates hydrogen gas even when the battery is not in operation make sure batteries are stored and worked on in well ventilated areas. ALWAYS wear safety glasses and a face shield when working on or near batteries.
