Arguably the best way to do this is to set up a small battery charging and storage station somewhere inside your home. Since your home has the benefit of heating and cooling, it remains relatively temperature-stable, so moving your batteries inside is all you need to do to protect them. Conseils et astuces L’idéal est de stocker les batteries lithium-ion avec un niveau de charge compris entre 30 et 60 pour cent. Pour les batteries Greenworks, cela correspond à deux LED allumées sur l’indicateur de niveau de charge. Heat is the fastest killer of batteries and electronics. Lithium-ion cells swell and lose capacity above roughly 90 degrees Fahrenheit, and extreme heat can damage the cell casing. Always avoid storing power tool batteries above 104 degrees Fahrenheit to prevent damage, as extreme temperatures can cause thermal decomposition of the battery components. Improper lithium battery storage is a leading cause of fires. Follow these safety guidelines to reduce risk at home, in your workshop, or across your EV fleet. I recently purchased a Greenworks leaf blower, and am unsure of how to store the battery. Ideally I would like to keep it in a shed outside, but the temperature here can get fairly high in the summer (usually averaging in the 90s on any given day). Install VENTS in your shed, the kind with shutters that 'fall' closed to prevent a draft when not in use. This is going to be important in summer. You'll want one vent at the bottom of one corner of the shed, and another (with an exhaust fan) at the top, opposite corner of the shed. Learn how to store household batteries safely, manage heat and moisture, extend shelf life, and keep backup power ready for everyday outages and short. Storing a battery in excessive heat can cause serious damage, reduce its lifespan, and increase safety risks, so it's important to understand how high temperatures affect battery performance. When stored in a shed without climate control, these items can easily become damaged or destroyed. A good general rule to follow is to avoid storing any sentimental or nonreplacable items in your storage shed, including artwork and photographs. Paper is also an ideal material for pest nests.
