Lead-acid batteries have been a widely used energy storage solution for many years. They are commonly used in backup power systems, renewable energy storage, and other applications. However, these batteries come in different variations, including flame-retardant (FR) and non-flame-retardant (non-FR) versions.
The key difference between these two types lies in their ability to resist the spread of fire. Flame-retardant lead-acid batteries are designed with special materials or coatings that slow or prevent the spread of fire in case of thermal runaway, an event where the battery overheats and potentially catches fire. On the other hand, non-flame-retardant lead-acid batteries do not feature these fire-resistant properties, making them more prone to fire hazards under extreme conditions.
