Making the Cool Choice: Storing Batteries in the Fridge and the Lithium vs. Alkaline Batteries Conundrum


Batteries are ubiquitous in our daily lives, powering everything from remote controls to essential electronic devices. As we seek to optimize their performance and longevity, questions arise about the best storage practices. In this article, we’ll explore the intriguing practice of storing batteries in the fridge and compare the characteristics of Lithium and Alkaline batteries to help you make informed decisions for your power needs.

Storing Batteries in the Fridge:

  • Temperature and Battery Performance:
    • Cool Environment: Storing batteries in the fridge is a common practice, with proponents suggesting that lower temperatures can slow down the chemical reactions within batteries, preserving their energy and extending overall lifespan.
    • Caution with Condensation: While cool temperatures can be beneficial, it’s important to be cautious about condensation. Moisture can damage batteries, so it’s recommended to place them in a sealed bag or container before refrigeration.
  • Types of Batteries Suitable for Refrigeration:
    • Rechargeable Batteries: Rechargeable batteries, such as nickel-metal hydride (NiMH) or nickel-cadmium (NiCd), can benefit from refrigeration. Storing them in a cool environment can help slow the self-discharge rate.
    • Alkaline Batteries: While some users refrigerate alkaline batteries to extend their life, the benefits are often marginal. Manufacturers typically recommend storing alkaline batteries in a cool, dry place.

Lithium vs. Alkaline Batteries:

  • Chemistry and Voltage:
    • Lithium Batteries: Utilizing lithium as the primary component, these batteries offer a higher voltage and energy density. They are lightweight, making them ideal for high-performance devices.
    • Alkaline Batteries: Employing a zinc-manganese dioxide chemistry, alkaline batteries are versatile and widely used. They provide a reliable source of power for various devices but have a lower voltage compared to lithium batteries.
  • Performance and Shelf Life:
    • Lithium Batteries: Boasting a longer shelf life and superior performance in extreme temperatures, lithium batteries are favored for high-drain devices and applications where reliability is paramount.
    • Alkaline Batteries: Alkaline batteries are suitable for everyday devices and have a decent shelf life. However, they may not perform as well as lithium batteries in high-drain situations.
  • Environmental Impact:
    • Lithium Batteries: Lithium batteries are not as environmentally friendly as alkaline batteries due to the mining and extraction processes required for lithium. However, they are recyclable, and recycling programs are becoming more widely available.
    • Alkaline Batteries: While alkaline batteries are less harmful to the environment, recycling is still recommended to minimize the impact of their components.


Storing batteries in the fridge can be a practical strategy, especially for rechargeable batteries, but precautions must be taken to avoid condensation. When considering Lithium vs. Alkaline batteries, the choice depends on your specific needs. Lithium batteries offer superior performance and longer life, making them suitable for high-drain devices. On the other hand, alkaline batteries are versatile and widely used in everyday devices, with the added benefit of being more environmentally friendly. Understanding the characteristics and storage needs of each battery type empowers you to make informed choices for optimal power performance.
