CALB 72ah CAM72 L135F72 3.2v LiFePO4 cell Precautions for Storage
The batteries should be stored (more than 1 month) in a clear, dry and ventilated room under ambient temperature of -20℃~25℃, and it should be kept away from caustic material, fire source and heat source. Do not invert battery during storage; and avoid mechanical shock and stress.
If the batteries kept for a long time, it should be charged and discharged at the standard model every six months. Store the battery in the state of 10%~30% SOC (voltage scope: 3.215V~3.305V).
