How long can a LiFePO4 battery sit unused?
LiFePO4 batteries can typically sit unused for 6–12 months without significant damage if stored at a 50% state of charge (SOC) in a cool, dry environment (10–25°C). Prolonged storage beyond this period may cause gradual capacity loss due to self-discharge (1–3% monthly). Regular voltage checks and partial recharging every 3–6 months help maintain longevity.
