Self-discharge of solar container lithium battery cells
All batteries slowly lose charge when left idle – Li-ion cells are no exception. This self-discharge ⇱ is built-in: tiny internal reactions (chemical side‐reactions and micro-shorts) bleed off energy over time. In this work, the self-discharge was measured at 30 °C for three cell types at various voltage levels for about 150 days in a constant voltage mode determining the current at a high precision (float current). This piece focuses on storage temperature, state of charge (SoC), and practical steps for lithium-based portable units used in camping, backup power. Lithium battery self-discharge refers to the natural reduction in a battery's charge over time while in an open-circuit state (i., not connected to a load or charger).
