All of the heated clothing products we sell at CozyWinters, including battery heated socks, jackets, vests, and gloves, are manufactured from quality materials that are designed to last for several seasons—so long as they are properly used and cared for. This applies not only to the garment itself, but also to the lithium ion batteries that power each piece.
Lithium ion batteries have very specific storage guidelines that, if not followed precisely, will result in damage, poor performance, and/or significantly reduced lifespan. In order to preserve your battery during periods of low or non-use, you must take the steps listed here.
- Discharge (or recharge) the battery to 40%.
- Disconnect the battery from the garment it is paired with.
- Store your lithium ion battery in a cool, dark place out of direct sunlight. Long-term exposure to heat and high temperatures is guaranteed to have a negative effect on your battery and prevent it from working the next time you need it.
- Do not allow lithium ion batteries or associated wires and chargers to come into contact with water or liquids of any kind.
- If storing a lithium ion battery for more than 90 days, be sure to turn it on, run it for a while, and recharge it back up to 40% before returning to storage.
Storing your battery heated clothing for spring and summer involves more than simply folding the garment up and putting it on the top shelf in your closet. You must take special care with the lithium ion batteries that come with the apparel, especially with regard to charge level, heat and moisture exposure, and length of storage. Following the guidelines above is the best way to ensure your battery heated clothing will work as intended when you pull it out next winter.
