Lithium-Ion Battery for Cold Storage

Green Cubes SAFEFlex lithium batteries include integrated heater packs that automatically maintain cell temperature in environments as cold as -40°C. This ensures full rated capacity is available for forklift operation in deep-freeze storage facilities without the performance degradation typical of unheated battery systems.

Lead-acid batteries lose 30–50% of their rated capacity in sub-zero temperatures due to the electrochemical properties of their sulfuric acid electrolyte. They also require removal from cold environments for equalization charging, creating condensation damage risks and operational delays. Lithium iron phosphate batteries with active thermal management eliminate these limitations.

SAFEFlex LFP batteries are rated for 3,000–5,000 charge cycles, corresponding to approximately 10 years of service in cold storage forklift applications. This is 2–3 times the typical lifespan of lead-acid batteries in the same environment, delivering a significantly lower total cost of ownership.

Yes. SAFEFlex batteries support in-situ opportunity charging directly within cold storage areas, eliminating the need to remove batteries and move them to a room-temperature charging room. This removes the risk of condensation damage and allows cold storage operators to recover battery room square footage.

Green Cubes SAFEFlex batteries are used by operators in food and beverage distribution, pharmaceutical cold chains, grocery retail fulfillment, and biotech storage. Any facility requiring reliable electric material handling equipment in refrigerated or frozen environments is a fit for SAFEFlex technology.
