While a swollen battery pack does not represent a safety concern, you should not use damaged
Battery storage, shelf life, self-discharge, and expiration
As soon as a battery is manufactured, it immediately begins to lose its charge—it discharges its energy. Discharge occurs at variable rates based on chemistry, brand, storage environment, temperature. Self-discharge denotes the rate at which the battery self-depletes in idle storage. All batteries self-discharge over time even when idle.
What Is Battery Storage Capacity?
Unlike lead acid batteries, Li-ion and LFP batteries suffer minimal degradation due to time — usage that, eventually causes their storage capacity to diminish. For example, EcoFlow''s award-winning EcoFlow DELTA 2 Max is powered by an LFP battery that offers 2048Wh of storage capacity and 2400W of AC Output ( 4800W surge
