1. Lead-Acid Batteries:
- Flooded (Wet Cell) Batteries: Flooded lead-acid batteries (with removable caps) have a shorter shelf life compared to other types. Under ideal storage conditions, they can last for about 6 to 12 months when kept in a fully charged state.
2. Sealed Lead-Acid Batteries (SLAs):
- Absorbent Glass Mat (AGM) Batteries: AGM batteries have an improved shelf life compared to flooded batteries. They can typically last for 12 to 18 months when stored correctly.
- Gel Batteries: Gel batteries also offer a longer shelf life and can last for up to 24 months or even longer when stored properly.
3. Lithium-Ion (Li-Ion) Batteries:
- Li-Ion batteries have the longest shelf life among the different battery types. Under optimal storage conditions, they can retain their charge for up to 2 to 3 years.
Please note that the shelf life of a car battery can vary based on the manufacturer and specific storage conditions. It is always recommended to refer to the manufacturer's guidelines for the exact shelf life of a particular battery model.
Also, proper storage is crucial for maintaining battery health and longevity. Batteries should be stored in a cool, dry, and well-ventilated area. Keeping them fully charged or at a partial state of charge is recommended to prevent sulfation and prolong the battery's lifespan.
