Rechargeable batteries power many everyday devices, from cordless tools to smartphones. However, proper disposal is important when these batteries reach the end of their useful life. Improper handling of old rechargeable batteries can pose significant risks to human health and the environment.
In this guide, we’ll show you how to dispose of your old rechargeable batteries safely and responsibly.
Types of Rechargeable Batteries
Before exploring disposal methods, you should be aware of the different types of rechargeable batteries and their potential environmental impact.
Here are the most common types of rechargeable batteries used in consumer electronics and tools:
- Lead-acid: Used in car batteries and uninterruptible power supplies
- Lithium-ion (Li-ion): Found in smartphones, laptops, and power tools
- Nickel-metal hydride (NiMH): Often used in digital cameras and remote controls
- Nickel-cadmium (NiCd): Common in older cordless tools and emergency lighting
Each type has unique characteristics and requires specific handling during disposal.
Environmental Impact of Improper Disposal
When rechargeable batteries end up in landfills, they can leak harmful chemicals into the soil and groundwater. These toxins can contaminate ecosystems, harm wildlife, and enter the human food chain. Additionally, improperly discarded batteries can cause fires in waste processing facilities, posing significant safety risks.
Preparing Batteries for Recycling
Before you can recycle your old rechargeable batteries, you need to properly identify and handle them.
Identifying Rechargeable Batteries
Rechargeable batteries often look similar to disposable ones, but there are a few key differences. Here’s how to identify them:
- Check for the recycling symbol (three arrows in a triangle)
- Look for labels indicating “rechargeable” or “Li-ion”
- Note any mention of nickel-cadmium, nickel-metal hydride, or lithium-ion
If you’re unsure, err on the side of caution and treat the battery as rechargeable.
Safety Precautions for Handling
When handling old rechargeable batteries, follow these safety guidelines:
- Inspect batteries for damage or leakage
- Use non-conductive tape to cover exposed terminals
- Store batteries in a cool, dry place away from metal objects
- Keep different types of batteries separated
These precautions help prevent short circuits and potential fires during storage and transportation.
Methods for Disposing of Rechargeable Batteries
Several options are available for safely disposing of your old rechargeable batteries. Each method has advantages, and the best choice may depend on your location and the number of batteries you need to recycle.
Retail Drop-Off Programs
Many retailers offer convenient drop-off locations for rechargeable battery recycling. These programs are often free and easily accessible.
Some popular options include:
- Battery supply shops
- Electronics retailers
- Home improvement stores, such as The Home Depot and Lowe’s
- Office supply chains, such as Office Max and Staples
In most cases, these locations have designated battery collection bins.
Mail-In Recycling Options
For those who don’t have convenient access to drop-off locations, mail-in recycling programs provide an excellent alternative. These services allow you to mail your batteries to a recycling facility.
Some manufacturers and recycling organizations offer free shipping labels, making the process even easier.
Local Recycling Centers
Many communities have dedicated recycling centers that accept rechargeable batteries. These facilities often handle a wide range of recyclable materials and can provide guidance on proper disposal methods.
Check with your local waste management authority for information on nearby recycling centers.

Additional Preparation Steps
Before taking your batteries to a drop-off site, consider these extra preparation steps to streamline the recycling process. Group batteries by type and label the container with the type and quantity. Mark any damaged or leaking batteries for special handling and keep them in transparent containers for easy inspection.
Locating a Drop-Off Site
The first step is to find a convenient drop-off location. Call2Recycle, a national collection program, maintains a network of about 30,000 retail stores that accept old rechargeables.
Here’s how to locate a drop-off site near you:
- Visit Call2Recycle.org or call 1-877-723-1297
- Enter your zip code to find nearby locations
- Note the operating hours and any specific drop-off instructions
Contacting the Facility
Before making a trip to your chosen drop-off location, it’s wise to call ahead. This extra step can save you time and ensure a smooth drop-off experience. When you call, make sure they accept the type of batteries you have. Ask about any preparation you need to do and the exact place to drop off the batteries in the store.
Transporting Batteries Safely
When transporting your batteries to the recycling location, place them in a non-conductive container (plastic or cardboard) and keep them separated to prevent contact between terminals. Secure the container to prevent spills or shifts during transport and avoid extreme temperatures.
What To Do When Recycling Is Not Available
In some cases, you may not find convenient recycling options in your area. Don’t despair—there are still steps you can take to dispose of your old rechargeable batteries responsibly. Let’s go over each option now.
Contacting Local Authorities
If you can’t find a recycling option through Call2Recycle or other programs, contact your local waste management department. They may be able to provide information on upcoming electronics recycling events or guidance on proper disposal methods. They may also know of alternative recycling options in your area. Some municipalities have special collection days for hazardous waste, including batteries.
Exploring Alternative Solutions
If local authorities can’t help, consider contacting the battery manufacturer for recycling options, checking with local schools or community centers for collection programs, or inquiring about battery recycling initiatives at your workplace.
If all else fails, call your local department of sanitation. Some will pick up rechargeables on electronics-collection days, or they can refer you to another collection spot.
Extending the Life of Rechargeable Batteries
While proper disposal is necessary, extending the life of your rechargeable batteries can reduce waste and save you money in the long run. Here are our tips to make them last longer.
Proper Charging Techniques
To get the most out of your rechargeable batteries, use the charger designed for your specific battery type. Also, avoid overcharging by unplugging once fully charged—that said, most newer batteries have “smart” charging that prevents this issue.
Don’t let batteries discharge completely before you recharge them—ideally, recharge them once they reach about 30%–50%. Charge at room temperature for optimal performance
Storage Best Practices
When not in use, store batteries at room temperature in a dry place. For long-term storage, keep batteries at about 40% charge.
Avoid storing batteries in extreme temperatures and check and recharge stored batteries every few months.
TOH Reader Tip: “Stick a piece of tape to a rechargeable battery you’ve just juiced up. That way, you’ll know it’s ready to go,” says Robert Lynch from Braintree, MA.
Our Conclusion
Proper disposal of old rechargeable batteries is a necessary step in protecting our environment and keeping our communities safe. By following our guidelines, you can responsibly recycle your batteries and contribute to a more sustainable future.
