• Most battery operated heated apparel uses Lithium-Ion batteries, similar to the typical cell phone battery. Proper care and storage of these batteries will ensure a lifespan of well over 500+ charge/discharge cycles.


  • Step 1: Connect the battery to heated apparel.
  • Step 2: Power on by pressing and holding the power button.
  • Step 3: To change temperature, press and hold the power button until LED light reflects desired settings. Note: some heated garments have an additional, separate power button. First, power on the battery, then press the garment power button to turn on the garment's power and to change the power level settings.

Battery Charging

  • Charge overnight for the initial charge - most batteries for heated clothing contain their own charging circuit that will automatically shut off when fully charged.
  • Charge to 100% before first full use.
  • A full charge on most standard batteries will take 3-4 hours.
  • A full charge on extended life batteries varies. Check with the manufacturer for specific charging times.

Testing Battery Charge

  • Disconnect battery from the product. Press and hold the battery power button. The LED indicator will show 1 to 4 LED lights to indicate the remaining power.


  • Disconnect the battery from the product when not in use, even if the power is turned off. The item may slowly drain power from the pack.
  • It is important to maintain at least 25% of the battery’s power when not in use. Charge the battery fully before storage, or battery life may be reduced over time. Set up a schedule to re-charge every 3 months when not in use over a longer period of time.

Flying with Batteries

  • When flying with Lithium-Ion batteries, the FAA has rules restricting the Watt-Hour maximum of each battery carried to 100 Wh. The typical 2.2Ah 7-volt Lithium-Ion battery used in the majority of heated apparel is approximately 15 Wh and extended-life batteries are approximately 28 Wh. There is no limit to the number of sub 100 Wh batteries that can be carried on a flight as long as they are for personal use.
  • More information on flying with batteries can be found through the FAA page linked here.

Here are some quick tips and battery instructions from TheWarmingStore.com





 We recommend charging overnight for the first charge.

 Charge 100% before use (a full charge takes about 3-4 hours).

 A red light usually appears on the wall charger when charging. If the light does not change or turn on, the battery may still be charging, so please test the battery in the product after 3-4 hours.

 Maintain at least 25% power when the battery is not in use. Cycling your batteries during the off-season will ensure longer battery life.


 Power on by pressing and HOLDING (2-4 seconds) the power button.

 To change temperature, press the power button until LED light reflects the desired setting. Power level setting can only be indicated when connected to the garment.

 To power off, push and hold down the button until the light goes out.

 If your garment has a touch button technology (eg. Mobile Warming), hold the button on the garment down for 2-3 seconds after turning on the battery and use this button to control temperature levels instead of directly from the battery.

Maintenance and storage: 

 Lithium-Ion cells used in heated apparel need to be stored at a 25% charge or more to prevent damage to cells.

 Leaving batteries below 25% for extended periods of time is the primary cause of loss of performance and damage, please fully charge your batteries before long term storage and periodically between seasons.


 Step 1: Charge the battery for 3-4 hours.

 Step 2: Plug the battery into the garment securely.

 Step 3: Hold the power button on the battery for 3 seconds.

 Is it turning on? Are any lights showing? It will take about 3-5 minutes for the garment to warm up.

 Are the batteries brand new?  If so and they are not turning on, it is probably a battery issue. 

 Are the batteries from last season? Like any other Lithium battery, it is important to continue to charge and drain the batteries during the offseason. Consider buying a new battery, and discard the old battery responsibly. 

 Does your garment have a touch button control? Check and see if there is a button on the item and follow the powering steps above. 


Please note most batteries have a 60-90 day warranty from the date of purchase.
