Why Expired Batteries Can Damage Your Devices

Batteries power countless devices in our everyday lives—from smartphones and laptops to toys, watches, and even medical devices like hearing aids. While we all rely on batteries to keep our gadgets running, not everyone understands the risks associated with expired batteries.

Using batteries that are past their expiry date can do more than just drain your device’s power faster. It can cause serious damage to your electronics, corrode contacts, and even pose safety hazards. In this article, we’ll explore why expired batteries can harm your devices and offer solutions on how to handle them safely.

What Happens to Batteries After They Expire?

Batteries are made up of chemicals and materials designed to store and release energy. Over time, the chemical reactions that produce power begin to slow down, and the materials inside the battery start to degrade. Here’s what happens when a battery expires:

1. Decreased Power Capacity: The chemical reaction inside the battery weakens, resulting in a significant loss of power capacity. Expired batteries often can’t hold a charge, meaning they will drain faster, causing your device to shut off unexpectedly or fail to operate at all.
   
   

2. Increased Leakage Risk: As batteries degrade, their outer casing may crack, leading to the leakage of toxic chemicals like alkaline, lithium, or acid. This can leak onto the contacts inside your device, causing corrosion that damages both the battery and the device itself.
   
   

3. Internal Pressure Buildup: In some cases, expired batteries (especially lithium-ion or rechargeable batteries) can develop internal pressure. This can cause the battery to swollen, crack, or rupture, posing a fire hazard or risk of explosion.
   
   

How Expired Batteries Can Damage Your Devices

Using expired batteries may seem like a minor issue, but the truth is that they can cause permanent damage to your devices in several ways:

1. Corrosion of Battery Contacts

When a battery begins to leak, the chemicals can seep out and come into contact with your device’s battery compartment. This can cause corrosion, which can short-circuit your device or destroy the internal contacts. Once corrosion sets in, your device may stop charging or fail to power up entirely.

• Example: Remote controls, clocks, and toys are all commonly affected by battery leaks. If you leave expired batteries inside these devices, you might find that even after replacing the batteries, the device doesn’t work anymore due to corroded connections.
  
  

2. Reduced Device Performance

When you insert expired batteries into a device, the voltage output is lower than normal, which can cause the device to behave erratically. Your device might freeze, malfunction, or shut down prematurely, even though the battery is technically still “installed.”

• Example: In cameras or flashlights, using expired batteries can result in dimmer lights or shorter usage times. For devices like smartphones, it can cause performance lag and may even result in the device shutting off suddenly when it detects a significant power drop.
  
  

3. Overheating and Fire Risks

In some instances, especially with lithium-ion batteries, the internal chemical reaction in the battery can become unstable as it ages. This can lead to overheating or thermal runaway, which may cause the battery to leak, swell, or even catch fire.

• Example: A laptop or electric vehicle using expired lithium-ion batteries could experience overheating, potentially damaging the internal components of the device. The heat can also warp or melt critical parts, leading to costly repairs.
  
  

4. Battery Swelling and Rupture

As batteries age, the internal chemical reaction becomes less efficient, sometimes causing gases to build up inside. This internal pressure can result in battery swelling. A swollen battery can physically damage the battery compartment, and in extreme cases, it may rupture, leading to potential safety hazards.

• Example: Some users have reported issues with smartphones or tablets when their battery swells. This pressure can push against the screen or the back casing of the device, making it difficult to use or even completely damaging the device’s internal components.
  
  

How to Avoid the Risks of Expired Batteries

Now that you know how expired batteries can damage your devices, here are some tips to help you safely handle batteries and avoid costly mistakes:

1. Check Battery Expiry Dates Regularly

Just like any other product, batteries come with expiry dates. Make it a habit to check the expiration date before inserting batteries into your devices. Most manufacturers provide an expiry date or a best-before date printed on the packaging or the battery itself.

• Tip: If you use batteries regularly, consider keeping a stock of fresh batteries and replacing expired ones before they are used.
  
  

2. Replace Batteries at the First Sign of Wear

Even before batteries officially expire, they may begin to show signs of wear. If you notice that your device is not holding a charge as well as it used to, or if you see any signs of leakage (dampness around the battery terminals), it’s time to replace them immediately.

• Tip: Rechargeable batteries like those in hearing aids, cameras, or power tools should be replaced or recharged when they show signs of wear or capacity loss.
  
  

3. Store Batteries in a Cool, Dry Place

Heat is one of the biggest accelerators of battery degradation. Make sure to store your spare batteries in a cool, dry place. Avoid storing them in hot environments like a car dashboard, where high temperatures can speed up the degradation process.

• Tip: Consider using a battery case or storage container to protect your batteries from extreme temperatures and humidity.
  
  

4. Recycle Expired Batteries Properly

Never throw expired or damaged batteries in the trash. Batteries, especially alkaline and lithium-ion types, can leak dangerous chemicals into the environment if not disposed of properly. Always recycle your old batteries at designated e-waste collection points or use retailers that offer battery recycling services.

• Tip: MyBattery.in offers an easy way to recycle your used batteries, with drop-off points across India. Make sure to recycle responsibly!
  
  

5. Don’t Leave Expired Batteries in Devices

If you’re not using a device for an extended period, remove the batteries before storing it. This will help prevent any potential leaks or corrosion from affecting the device.

• Example: For devices like watches, clocks, or remote controls that you don’t use frequently, always remove the batteries to ensure they stay in good condition.
  
  

What to Do if Your Device Has Been Damaged by Expired Batteries

If your device has been damaged due to expired or leaking batteries, don’t panic. There are a few steps you can take:

• 1. Clean the Corroded Area: If you notice battery leakage or corrosion inside the device, use a soft cloth or cotton swab to gently clean the terminals. Use a mixture of baking soda and water (1:1 ratio) for a more thorough cleaning.
  
  

• 2. Replace Damaged Parts: If the corrosion has caused physical damage to the contacts or terminals, you may need to replace parts of your device, like the battery compartment or internal circuitry.
  
  

• 3. Take It to a Professional: If the damage is significant, consider taking your device to a professional for repair. In cases of swollen batteries, do not attempt to handle or puncture the battery yourself.
  
  

Conclusion

Expired batteries are more than just a minor inconvenience—they can seriously damage your devices and pose safety risks. From corrosion to overheating, expired batteries can have long-lasting effects that may cost you more than just a replacement battery.

To keep your devices running smoothly, always check the expiry dates of your batteries, replace them when necessary, and dispose of them responsibly. By taking the time to maintain your batteries, you can avoid unnecessary repairs, extend the life of your devices, and even prevent safety hazards.
