Laptop Battery Freezer Myth: Should You Store Batteries in the Freezer?

In the realm of battery storage, myths abound regarding the efficacy of freezing batteries to extend their lifespan or rejuvenate their charge capacity. This article dives deep into the popular belief that placing batteries, including laptop batteries, in the freezer can enhance their performance and longevity. We’ll explore various types of batteries, the science behind their storage conditions, and finally, provide practical advice on how best to store them.

Understanding the Freezer Battery Myth

The Origins of the Myth

The idea of storing batteries in the freezer stems from a time when older battery technologies, like nickel-cadmium (Ni-Cad), were prevalent. Back then, it was believed that low temperatures could slow down the self-discharge rate of these batteries, thus preserving their charge for longer periods.

Types of Batteries and Their Reactions to Freezing

Ni-Cad Batteries

  • Will a Ni-Cad Battery Stay Charged Longer in the Freezer? The concept of freezing Ni-Cad batteries to maintain charge is rooted in their older chemistry. However, modern Ni-Cad batteries are less common due to environmental concerns and have specific storage recommendations that do not typically involve freezing.

NiMH Batteries

  • Can You Put NiMH Batteries in the Freezer? Nickel-metal hydride (NiMH) batteries, commonly found in household electronics, do not benefit from freezing. In fact, extreme temperatures can degrade them faster, leading to reduced performance and capacity over time.

Alkaline Batteries

  • Will Freezing Alkaline Batteries Extend Their Life? Alkaline batteries are not designed to be frozen. Freezing can cause the electrolyte inside to expand, potentially damaging the casing and leading to leakage or rupture.

Lithium Ion Batteries

  • Should You Store Lithium Ion Batteries in the Freezer? Lithium ion batteries, used in laptops and smartphones, should never be frozen. Freezing can permanently damage the battery cells, leading to reduced capacity and potentially hazardous situations.

Debunking the Freezer Battery Myth

The overarching principle with modern batteries, especially lithium-based ones, is that they should be stored at moderate temperatures, ideally between 15°C to 25°C (59°F to 77°F). Here’s why freezing isn’t recommended:

  • Chemical Reactions: Freezing temperatures can alter the chemical composition of batteries, affecting their ability to hold a charge or deliver power efficiently.
  • Physical Damage: Some batteries, like lithium ion, contain sensitive components that can be irreversibly damaged by freezing temperatures, leading to safety hazards.
  • Moisture Concerns: Condensation can form inside batteries when they are moved from freezing temperatures to warmer environments, potentially causing internal corrosion or short circuits.

Practical Tips for Battery Storage

Best Practices for Storing Batteries

When it comes to storing batteries, especially if you’re wondering about laptop battery freezer myths or storing batteries in the freezer:

  1. Temperature Control: Aim for a cool, dry place with consistent temperatures.
  2. Avoid Extreme Heat or Cold: Keep batteries away from direct sunlight, heaters, or freezing environments.
  3. Use Original Packaging: Store batteries in their original packaging or specialized battery cases to protect against physical damage.
  4. Check Charge Levels: Periodically check and recharge batteries to maintain optimal performance.

FAQs About Freezing Batteries

Q: Do Batteries Last Longer in the Freezer?

A: No, freezing batteries, especially modern lithium ion batteries, can actually shorten their lifespan and impair performance.

Q: Can You Rejuvenate a Lithium Ion Battery in the Freezer?

A: No, freezing a lithium ion battery can permanently damage it and should be avoided.

Q: Will Putting Alkaline Batteries in the Freezer Extend Their Shelf Life?

A: No, freezing alkaline batteries can cause leakage or rupture due to expansion of the electrolyte.

Q: Should I Store Laptop Batteries in the Freezer?

A: Absolutely not. Laptop batteries are typically lithium ion and should be stored in a cool, dry place.


In conclusion, the myth of storing batteries in the freezer, including laptop battery freezer myths, stems from outdated practices and misunderstandings about battery chemistry. Modern batteries, such as lithium ion and NiMH, are best stored in controlled environments with moderate temperatures and low humidity. Freezing batteries not only fails to extend their life but can actually harm them irreversibly. Therefore, to ensure optimal performance and longevity of your batteries, follow manufacturer recommendations and avoid falling prey to misconceptions about freezer storage. Remember, a little knowledge about proper battery care goes a long way in maximizing their usefulness and safety!
