How to Correctly Dispose of Used Batteries

November 21, 2025

Batteries power our daily lives, but once they run out, tossing them in the bin is a serious mistake. Improper disposal harms the environment, contaminates soil and water, and endangers wildlife.

If you want to do your part, here is a simple guide on how to correctly dispose of batteries while keeping Singapore clean and green.

Think Twice Before Tossing – Why Battery Disposal Matters

Recycling batteries does more than just keep them out of landfills. Here is why it is a smart and responsible choice:

• Reduces Environmental Pollution
  Batteries hold toxic substances such as lead, mercury, and cadmium. When dumped in general waste, these toxins can seep into the ground. They contaminate drinking water and harm ecosystems.
  
  Recycling used batteries prevents these hazardous substances from polluting the soil and water.

• Prevents Fire Hazards
  Some batteries can explode if crushed or exposed to heat, posing serious fire risks. Proper disposal minimises this danger, ensuring safer waste management.

• Conserves Natural Resources
  Recycling allows valuable materials like lithium, cobalt, and nickel to be recovered and reused. This reduces the demand for raw material extraction and helps conserve natural resources.

• Supports Green Energy Efforts
  Recycled materials can be used in new batteries, decreasing the need for mining and supporting sustainable energy practices. Choosing to recycle is essential for a cleaner and safer world.

Think Your Battery Disposal Is Safe? Check Again

Many people unknowingly dispose of batteries incorrectly, thinking it is harmless. Here are some common battery disposal mistakes you might be making:

• Tossing Batteries Into Regular Bins
  This sends them straight to landfills, where toxic chemicals leak into the environment.

• Burning Old Batteries
  Some people think burning eliminates waste, but it actually releases harmful fumes and increases fire risks.

• Mixing Different Battery Types
  Storing or disposing of different battery chemistries together can cause leaks or even explosions.

If you have disposed of batteries this way before, do not worry. The good news is that proper battery disposal is easier than you think!

Know Your Batteries – Different Types, Different Disposal Methods

Not all batteries are the same. Some can be recycled easily, while others need special handling. Here is what you need to know:

1. Alkaline Batteries (AA, AAA, C, D, 9V)

These are commonly used in remote controls, clocks, and toys. Alkaline batteries contain less harmful chemicals, so they can be disposed of in general waste. However, recycling is always a better option to reduce landfill waste.

2. Lithium-ion Batteries (Phone, Laptop, Power Bank, Electric Vehicles)

These are rechargeable and found in most electronic devices. They must never go into regular bins as they pose a fire risk. Instead, take them to an e-waste collection point for safe recycling.

3. Button Cell Batteries (Watches, Hearing Aids, Medical Devices)

These small batteries contain mercury or silver oxide, making them highly toxic if not disposed of properly. Drop them off at designated e-waste bins for safe handling.

4. Lead-Acid Batteries (Car, Motorcycle, Industrial Equipment)

These large batteries are hazardous but highly recyclable. Many automotive shops accept used lead-acid batteries and send them for proper recycling.

Best Practices – Storing and Preparing Batteries for Disposal

Before you drop off your used batteries, take these safety steps:

• Tape the Terminals
  This prevents short circuits and reduces fire risks.

• Store in a Cool, Dry Place
  Avoid heat and humidity, which can cause leaks.

• Do Not Mix Battery Types
  Separate rechargeable and non-rechargeable batteries to prevent reactions.
