Batteries

Words of caution: Lead-acid batteries contain a sulfuric acid electrolyte, which is a highly corrosive poison and will produce gas when recharged and explode if ignited. This will hurt you--BAD! 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, please follow the manufacturer's instructions for testing, jumping, installing, charging and equalizing batteries.

These pages assume 12-volt, six cell, negative grounded, deep cycle lead-acid batteries found in most recreational and deep cycling applications. The information contained within the sections would also apply to deep cycle batteries used in motive, traction, stand-by and float applications. For six-volt batteries, divide the voltage by two; for eight-volt batteries, divide by 1.5; for 24-volt batteries, double the voltage; for 36-volt batteries, triple the voltage; and for 48-volt batteries, multiply by four.
