1. Lead-Acid Batteries:
- Flooded Lead-Acid Batteries: These batteries have a shorter shelf life. If stored properly in a cool, dry environment, they can last around 6 to 12 months.
- Sealed Lead-Acid Batteries: These batteries, also known as maintenance-free batteries, can last longer on the shelf. When properly stored, they can retain their charge for up to 18 to 24 months.
2. AGM (Absorbent Glass Mat) Batteries:
AGM batteries are known for their extended shelf life compared to traditional flooded lead-acid batteries. When stored correctly, they can retain their charge for up to 12 to 18 months.
3. Gel Batteries:
Similar to AGM batteries, gel batteries also have a long shelf life. If properly stored, they can last up to 18 to 24 months while holding their charge.
4. Lithium-Ion (Li-Ion) Batteries:
Li-Ion batteries are commonly found in hybrid and electric vehicles. These batteries have excellent shelf life and can retain their charge for up to 3 to 5 years when properly stored.
It's important to note that the shelf life mentioned above is based on ideal storage conditions and proper maintenance practices. Factors like high temperatures, excessive humidity, or prolonged periods of discharge can shorten battery life.
Here are some tips to extend the shelf life of a car battery during storage:
1. Store the battery in a cool, dry location, ideally between 50°F and 75°F. Avoid extreme temperatures.
2. Maintain optimal humidity levels to prevent corrosion.
3. Keep the battery terminals clean and free of corrosion.
4. Avoid leaving the battery completely discharged for extended periods.
5. If storing for more than a few months, perform regular maintenance by charging and discharging the battery as per manufacturer recommendations.
Following these guidelines can help maximize the shelf life and ensure your car battery is ready to use when needed.
