LiFePO4 batteries perform optimally at moderate temperatures. Extreme cold can affect their capacity and efficiency. While these batteries are more resilient than traditional lithium-ion batteries, they still benefit from temperature management. LiFePO4 batteries have a low self-discharge rate, typically around 3-5% per month.
LiFePO4 batteries have a low self-discharge rate, typically around 3-5% per month. This characteristic makes them suitable for long-term storage. However, even with low self-discharge, monitoring is essential to prevent deep discharges. Before storing your LiFePO4 batteries for winter, charge them to approximately 50% capacity.

As winter approaches, proper storage of Lithium Iron Phosphate (LiFePO4) batteries becomes crucial for maintaining their performance and longevity. These batteries are known for their safety, efficiency, and long cycle life, but they still require specific care during colder months.
Lead-acid batteries do experience a reduction in capacity in colder weather. Typically, capacity diminishes by about 20% in normal cold conditions and can drop by approximately 50% at temperatures as low as -22°F (-30°C).
I have done a search both on the internet and here on the forum. There just doesn't seem to be a consensus. Most everyone agrees that 1) never charge or attempt to charge the LifePO4 battery below 32 degrees F. 2) if storing for more than a month the battery should be left at partial charge somewhere between 40-60%.
