A lead acid battery consists of several major components, including the positive electrode, negative electrode, sulphuric acid, separators, and tubular bags.

Are lead-acid batteries water-resistant?

Lead-acid batteries: These batteries, often used in vehicles, can be filled with a type of liquid (diluted sulfuric acid), so they're somewhat water-resistant. However, water entering the battery can dilute the acid and reduce its performance.

Does flooded electrolyte lead acid battery cause thermal runaway?

Flooded electrolyte lead acid batteries do not cause thermal runaway because the electrolyte, which acts as a coolant in these batteries, helps prevent such an occurrence. Designers of flooded electrolyte lead acid batteries do not face the thermal runaway problems that are common in sealed maintenance free (SMF) or valve regulated lead acid (VRLA) batteries.
