How Does It Work?
Freezing old alkaline batteries temporarily slows down the chemical reactions inside the battery that cause it to lose power. When you bring them back to room temperature, they can regain some of their voltage and be useful again — at least for a short time.
Important Tips and Safety Precautions
-
Only try this with alkaline batteries — do NOT attempt to recharge or freeze lithium-ion, rechargeable NiMH, or lithium batteries. These types require proper chargers and can be dangerous if mishandled.
-
Always handle batteries carefully. If a battery is leaking, swollen, or damaged, dispose of it safely — do not reuse it.
-
This trick won’t make dead batteries brand new, but it can give you extra time before needing replacements.
-
Consider investing in rechargeable batteries for a more sustainable long-term solution.

Next time your remote control or wireless mouse stops working, don’t rush out for new batteries just yet. Try this simple freezing trick and see if you can get more life out of your old batteries. It’s an easy, budget-friendly, and eco-conscious hack that many people don’t know about — but definitely should!
