A reliable power source is one of the most important things you can have under extreme conditions. You should know how cold weather affects batteries before you decide which one is best for your situation. In cold weather, it can be treacherous to live off-grid, and you need to be sure that you have everything you need. However, lead-acid batteries tend to perform less well than their lithium counterparts. For anyone who wants to explore places where temperatures can drop to frigid temperatures, lithium batteries make a great power source. We examine in this article why lithium batteries are the best option and how our SLAR series batteries are superior in cold weather.
It is possible to use LFP batteries in temperatures as low as -4 degrees Fahrenheit, as well as as high as 140 degrees Fahrenheit. Off-grid solar, RV, and Camper Van owners live and travel in extremely cold climates, so lithium batteries offer a reliable, consistent source of power. If you own a battery, you must keep in mind that cold temperatures can harm the battery’s health. Typically, lead-acid batteries are severely damaged by the cold, which severely deteriorates their health and longevity. Lithium batteries perform better in colder temperatures than lead-acid batteries. Typically, the more power you pull from a lead-acid battery in cold temperatures, the weaker it becomes. As you use LFP batteries, their resistance decreases and their voltage increases. In cold climates, lithium is the clear winner when it comes to upgrading or overcoming battery problems.
Despite being lithium-powered, cold weather can affect battery life. Lead-acid batteries will provide 70-80% of their rated capacity when temperatures are below 32 degrees. On the other hand, at the same temperature, lithium batteries provide 95-98% of their rated capacity with very small losses.
Anodes, the negative terminal of the battery, are made of porous graphite, which absorbs lithium ions like a sponge when charged above freezing temperatures. As a result, the anode cannot capture lithium ions effectively below freezing. A process called lithium plating causes many lithium ions to coat the anode, reducing the amount of lithium available for electricity flow. As a result, the battery’s capacity decreases. When the battery is charged below freezing at an inappropriate rate, it becomes less mechanically stable and more susceptible to sudden failure.
During freezing charging, lithium ions get lost while navigating to “work” within the graphite anode. Plating occurs when these ions do not intercalate, which reduces battery capacity and increases resistance. Charging in freezing temperatures can result in plating. A dangerous short within the cell can occur if enough plating builds up and punctures the separator.
