To ensure optimal performance and longevity of your battery, we recommend to avoid leaving the battery connected to the charger for extended periods. Ideally, recharge the battery after each use, such as at the day's end, and avoid letting it fully discharge before recharging. Never restart the jacket when the battery is empty to avoid complete drainage. When storing, disconnect the battery from the garment and fully recharge it beforehand. Additionally, every three to four months, recharge it again to maintain its capacity effectively. These practices will help preserve the battery's lifespan and ensure consistent performance.
