What are the best storage conditions for traction batteries?
Batteries should be stored in a clean, cool, dry and well ventilated location away from radiators, heating ducts or other sources of heat and protected from exposure to direct sunlight. Before storing, it is necessary that the battery be fully charged and the electrolyte at the proper level. Disconnect leads or cable connections to prevent use or possible discharge through tracking during prolonged storage. Do not remove the electrolyte or strip out the cells. If the storage temperature is 25°C or higher, check the specific gravity at least once a month. If it is below 25 o C, every second month. Whenever the specific gravity falls to about 1.230 or lower, give a freshening charge. Always give a freshening charge prior to returning to service.
