Important Battery Note
The required electrolyte density depends on battery design, state of charge and manufacturer specification.
Mining Chemicals SA should not present 38% as universally correct for every lead-acid battery.
Storage & Safety
Highly corrosive. Store in compatible acid-resistant containers and segregate from bases and incompatible materials.
