Your heated apparel is only as good as the power behind it — that’s why proper battery care matters.
To help you get the most out of your CozyCoreWear rechargeable battery and ensure safe, long-lasting performance, please read this guide carefully before use.
1. Important Note on Cold Weather Performance
Like all lithium batteries, your CozyCoreWear battery may not perform properly in extreme cold (around or below 0°C / 32°F).
If the temperature is very low, allow the battery to warm up to room temperature before turning on your heated vest, jacket, or gloves.
This helps maintain stable power output and protects internal components.
2. Battery Life Expectancy
Our rechargeable batteries are designed to last approximately 500 charge/discharge cycles under normal use conditions.
Actual lifespan depends on how frequently you use and recharge your heated clothing.
To keep your battery healthy for years to come, follow the care tips below.
3. How to Extend Battery Life
Proper maintenance can significantly improve battery longevity.
Here’s what we recommend:
-
Fully charge and discharge your battery every 3–6 months, even during warmer seasons when you’re not using your heated gear.
-
To perform a maintenance cycle:
-
Fully charge your battery.
-
Plug it into your heated apparel and turn it on.
-
Let it run until fully discharged.
-
Recharge it completely again.
-
-
Store the battery in a cool, dry location, away from direct sunlight or heat sources.
💡 Long periods of inactivity can degrade lithium batteries, so giving your battery an occasional workout keeps it performing like new.
4. Safe Disposal and Recycling
Never throw lithium batteries in the trash.
They can be hazardous to both people and the environment.
Instead, please recycle your used batteries responsibly.

5. Traveling With Your Battery
Good news — CozyCoreWear batteries are FAA-compliant and safe for air travel.
However, per airline and FAA regulations, you must:
-
Pack batteries in your carry-on baggage, not checked luggage.
-
Ensure the terminals are covered or insulated to prevent accidental contact.
If you’re unsure about specific airline policies, check with your carrier before your flight.
6. Compatibility and Safety
For your safety and product performance, only use official CozyCoreWear batteries and chargers.
Do not attempt to use third-party or off-brand batteries.
Different batteries can have incompatible voltage or current ratings — using an unapproved battery could damage your gear or even cause overheating or fire.
⚠️ Always choose genuine CozyCoreWear replacement batteries to ensure safe and consistent performance.
