Unveiling the Truth: Batteries in the Freezer – Do They Last Longer?

Have you ever wondered about the mysterious relationship between batteries and your freezer? Can freezing batteries really make them last longer? What about reviving a swollen lithium-ion battery or changing the battery in your Kenmore Elite freezer? In this comprehensive guide, we delve deep into these questions and more, uncovering the truth behind the myths and offering practical advice for battery care in your household appliances.

Freezing Batteries: Fact or Fiction?

The practice of freezing batteries to extend their life has been a subject of debate among tech enthusiasts and DIYers for years. Let’s break down the facts and myths surrounding this intriguing topic.

Myth: Freezing Batteries Automatically Extends Their Life

It’s often believed that storing batteries in the freezer can slow down their discharge rate, preserving their charge for longer periods. However, the reality is more nuanced:

  • Temperature and Chemistry: Batteries are designed to operate optimally at room temperature. Freezing batteries, especially alkaline ones, can slightly prolong their shelf life but may not significantly enhance their performance once in use.
  • Risk of Damage: Extreme cold can cause batteries to leak or rupture due to expansion of internal components. This risk is higher with older or damaged batteries.

Fact: Freezing for Specific Scenarios

While freezing batteries may not universally extend their life, it can be beneficial in certain situations:

  • Storing Emergency Batteries: Freezing spare batteries for emergency use can help maintain their charge over extended periods, especially in power outage scenarios.
  • Reviving Swollen Batteries: In cases of lithium-ion batteries swelling due to age or overuse, freezing can temporarily reduce swelling and stabilize the battery for safer disposal or recycling.

How to Revive a Swollen Lithium-ion Battery from Your Kenmore Elite Freezer

Discovering a swollen lithium-ion battery in your Kenmore Elite freezer can be alarming. Here’s a step-by-step guide on safely managing and potentially reviving such batteries:

  1. Identify the Swelling: A swollen battery will typically appear larger than normal and may be bulging at the sides or ends.
  2. Safety First: Wear protective gloves and eyewear before handling swollen batteries to avoid any potential chemical leakage.
  3. Freeze the Battery: Place the swollen battery in a sealable plastic bag and then into the freezer for 24-48 hours.
  4. Disposal: After freezing, remove the battery from the freezer and dispose of it according to local hazardous waste regulations. Do not attempt to reuse a swollen battery.

Can You Change the Battery in Your Fisher Scientific Freezer Keypad?

The Fisher Scientific freezer keypad is crucial for maintaining temperature and settings in your freezer. Here’s what you need to know about changing its battery:

  • Battery Type: Typically, the Fisher Scientific freezer keypad uses a small button cell battery (e.g., CR2032).
  • Replacement Procedure:
    1. Locate the battery compartment on the back or underside of the keypad.
    2. Use a small screwdriver to open the compartment and carefully remove the old battery.
    3. Insert the new battery with the correct polarity (+/-).
    4. Close the compartment securely.

FAQs About Batteries in the Freezer

Q: Does putting batteries in the freezer extend their life?

A: Freezing batteries may marginally extend shelf life but won’t significantly enhance performance once in use.

Q: How do you revive a swollen lithium-ion battery?

A: Freezing a swollen lithium-ion battery can temporarily reduce swelling, making it safer for disposal.

Q: Can I use frozen batteries right away?

A: Allow frozen batteries to return to room temperature before use to avoid potential damage.


In conclusion, while freezing batteries can have limited benefits such as prolonging shelf life and stabilizing swollen lithium-ion batteries, it’s not a cure-all for extending their overall performance. Understanding when and how to freeze batteries, as well as safely managing swollen batteries like those in your Kenmore Elite freezer or Fisher Scientific keypad, ensures optimal usage and safety in your household appliances. Remember, always prioritize safety and follow manufacturer guidelines when handling and disposing of batteries.

Next time you ponder whether freezing batteries—do batteries last longer in the freezer, or how to revive a swollen battery, remember the insights from this guide. Armed with this knowledge, you can make informed decisions to maximize battery life and efficiency in your everyday devices.
