Page 6: Brief Introduction
The state of the battery when placed into storage will affect how long it can be stored as well as the battery’s condition when it is brought out of storage. EG4 recommends that each battery is brought to a 100% SOC (state of charge) before placing it in storage. Lithium iron phosphate batteries will lose a certain percentage of their total charge while in storage, depending on how long they are stored and the conditions they are stored in. -
