In our last post, we talked about how you should wash your battery heated jacket, gloves, and liners before storing them for the summer to help ensure they’re ready for action as soon as you need them again. This time around, we’re going to focus on battery care for those same products.

Most of the battery heated clothing we sell at CozyWinters is powered by lithium ion (Li-ion) battery packs. These battery packs are consumable, meaning they have a limited shelf life, and are designed to last anywhere from 300 to 500 discharge cycles. With proper storage and care, lithium ion battery packs will consistently hit the upper end of their lifespan, so we suggest that you follow these tips:

• Never store a lithium ion battery pack in a completely discharged state. Instead, a 25% to 60% charge is recommended prior to storage.
• Disconnect the battery pack from its connectors and remove it from the device before placing it into long-term storage.
• Store lithium ion battery packs in a cool, dry place away from direct sunlight and extreme changes in temperature.
• Recharge the battery pack at least once every three to six months regardless of whether or not you intend to use the garment it powers. This will help improve performance and extend battery life in the long run.

The batteries in your CozyWinters heated apparel require special care to keep them operating at peak performance levels and promote overall longevity, so make it a point to follow these guidelines for summer and offseason storage.

Please keep in mind that different manufacturers may have different storage protocols for their batteries, so the above tips are simply intended to be general guidelines rather than specific instructions.
