Systems should be put into storage at 60% SOC and checked monthly to ensure the system SOC
does not fall below 20%. At 20% SOC the battery will self-discharge in approximately 2 months. Also
check the voltage every 3 months and recycle every 6 months if the battery is not use for long time.
2.3 Response to emergency situations
The battery pack comprises multiple batteries that are designed to prevent hazards resulting from
failures. However, Fortress Power cannot guarantee their absolute safety.
❖ Leaking Batteries
❖ If the battery pack leaks electrolyte, avoid contact with the leaking liquid or gas. If one is
exposed to the leaked substance, immediately perform the actions described below.
➢ Inhalation: Evacuate the contaminated area and seek medical attention.
➢ Contact with eyes: Rinse eyes with flowing water for 15 minutes and seek medical
attention.
➢ Contact with skin: Wash the affected area thoroughly with soap and water, and seek
medical attention
➢ Ingestion: Induce vomiting, and seek medical attention
❖ Fire
➢ In case of fires, make sure that the extinguisher is available near the battery pack. If
possible, move the battery pack to a safe area before it catches fire.
Note: FM-200 fire extinguishers, sands, carbon dioxide, dry chemical powder and foam are
the most effective means to extinguish a Lithium Ferrous Phosphate (LFP) battery fire
➢ Use ABC Fire extinguisher, if the fire is not from battery and not spread to it yet.
