Batteries stored at a higher state of charge typically experience higher self-discharge rates. It's often recommended to store lithium-ion batteries at a moderate charge level to minimize self-discharge while ensuring they are ready for use when needed. Battery Chemistry:
Keeping batteries at lower charge levels, around 40%-60% state of charge, diminishes degradation reactions, contributing to lower self-discharge rates during prolonged storage periods. Battery age As lithium-ion batteries age, the degradation of internal components such as electrodes and electrolytes leads to higher self-discharge rates over time.
