The following tips will help you extend the life of your batteries. When not using heated clothing for a long time, fully charge the batteries and disconnect them. During the off-season, remember to charge batteries every 3-months. This ensures they maintain an adequate charge and are ready to use in winter. Charging the battery between 20% and 80% is a good habit. Avoid constantly charging it to 100%, as it wears out batteries over time. Avoid letting the battery drain entirely, as it can be harmful in the long run. Occasionally, it's not very damaging, but frequent drainages can reduce the battery's lifespan. Note that batteries operate best at moderate temperatures, ideally between 20°C to 25°C (68°F to 77°F). Avoid extreme temperatures and keep your heated garments away from direct sunlight, hot cars, or very hot places.
