If you’ve been doing a deep clean of your garage, office, or that infamous “junk drawer” in the kitchen, you’ve probably found them: old cell phones, a dusty laptop, or a pile of mysterious batteries that don’t look like standard AAs.
You know you shouldn’t just toss them in the trash. (Spoiler: You really, really shouldn’t.) But what should you do?
Lithium-ion batteries power our modern lives, from our smartphones to our power tools, but they can be tricky to dispose of. In fact, because they hold so much energy, they are classified as hazardous waste. If crushed in a garbage truck, they can start dangerous fires.
At Grunber, we believe in making junk removal simple, safe, and eco-friendly. That’s why we’ve put together this simple guide on how to identify, handle, and dispose of lithium-ion batteries safely.

Why You Can’t Just Throw Them in the Trash (The “Spicy” Truth)
It might be tempting to hide that old phone battery at the bottom of a trash bag, but that is a dangerous gamble.
Lithium-ion batteries contain a flammable liquid inside. When these batteries end up in a regular garbage truck or a municipal recycling facility, they get crushed by compactors meant for old sofas or cardboard boxes. Puncturing the battery causes a short circuit, creating a chemical fire that is incredibly difficult to put out.
According to the EPA and fire safety experts, lithium-ion batteries are a leading cause of fires in waste facilities across the US. By keeping them out of the bin, you aren’t just following the law—you’re protecting sanitation workers, truck drivers, and your own community.
Why Batteries Don’t Belong in the Bin
Check out this quick explanation on why these batteries are different from your standard trash:
How to Identify a Lithium-Ion Battery
Not all batteries are the same. Before you toss them, check the label:
| Battery Type | What it Looks Like | Can it go in the trash? |
| Alkaline | Standard AA, AAA, C, D (TV remotes, flashlights). | Yes (in most places), but recycling is better. |
| Lithium-Ion (Li-ion) | Rectangular (phones), Hard Plastic Packs (drills), or marked “Rechargeable.” | NO. Must be recycled specially. |
| Button Cells | Silver coins (watches, car fobs). Often Lithium-based. | NO. Treat as hazardous. |
Pro Tip: If the battery is rechargeable, assume it cannot go in the trash. Look for the recycling symbol with a battery icon or the words “Li-ion.”
Step-by-Step Disposal Guide
1. The “Tape” Method (Crucial for Safety)
Before you drive anywhere or hand batteries over to a recycler, you need to make them safe. If the metal terminals (the positive + and negative – ends) touch keys, coins, or other batteries, they can spark.
- Grab some tape: Clear packing tape, electrical tape, or duct tape works best.
- Cover the ends: Place a strip of tape over the contact points.
- Bag it: Alternatively, place each battery in its own individual plastic sandwich bag (Ziploc).
2. What to Do with “Spicy Pillows” (Swollen Batteries)
If you find a battery that looks puffy, swollen, or smells sweet (like chemicals), it is damaged. The internet calls these “spicy pillows,” but they are serious fire risks.
- Do NOT put this in a retail kiosk or mail-in box.
- Do NOT squeeze or puncture it.
- Safe Storage: Place the swollen battery in a metal bucket or cooking pot filled with sand or kitty litter. This acts as a fire buffer.
- Disposal: Take it directly to your local Household Hazardous Waste (HHW) facility and tell the attendant immediately. Do not hide it in a pile of other junk.
3. Where to Take Intact Batteries
You have a few convenient options for safe disposal:
- Option A: Retail Drop-Offs (Best for Small Amounts)
Major retailers like Home Depot, Lowe’s, Best Buy, and Staples participate in the Call2Recycle program. They usually have collection boxes near the entrance where you can drop off rechargeable batteries and old cell phones for free.
Note: They typically do not accept loose alkaline batteries or damaged ones.
- Option B: Household Hazardous Waste (HHW) Sites
For large buckets of batteries or damaged ones, check your town’s municipal website for “hazardous waste drop-off days.”
- Option C: The Grunber Solution (The Easiest Way for E-Waste)
If you are clearing out an entire office, dealing with an estate cleanout, or just have too much junk to sort, you might have old electronics mixed in with furniture and boxes.
Grunber specializes in E-Waste Removal. We can pick up:
- Old Laptops and Computers
- Televisions and Monitors
- Printers and Scanners
- Old Cell Phones and Tablets
How it works: You don’t need to wrestle the batteries out of these devices. Leave them intact! Our vetted driver teams will haul the junk away and transport the electronics to certified e-waste recyclers. There, the batteries are professionally removed and recycled, and the valuable metals are recovered to make new gadgets.
Important Policy Note: For the safety of our drivers, we generally cannot accept bags of loose, leaking, or swollen batteries. Please handle those via the retail or HHW steps above, and let us handle the heavy lifting for everything else!
Frequently Asked Questions
Q: Can I put lithium batteries in the curbside recycling bin (blue bin)?
A: No! Never put them in the blue bin. They cause massive fires in the sorting machines at recycling centers.
Q: What if the battery is glued inside my phone/laptop?
A: Don’t try to pry it out—you might puncture it. Take the whole device to a retailer like Best Buy or book a Grunber pickup for “E-Waste,” and we’ll handle the device safely.
Q: Do I really need to tape the ends?
A: Yes. It takes two seconds and prevents the battery from sparking against keys or coins in your bag, which could start a fire in your car on the way to the recycling center.
