The rate of self-discharge is also heavily dependent on temperature. The hotter a given battery is, the quicker it will self-discharge. Most lithium-ion batteries have a self-discharge rate of between 0.5-3% per month. This means that lithium battery will lose between 0.5 and 3% of its charge per month.

The self-discharge of lithium-ion batteries is affected by battery state of charge (SOC) . Under the same conditions, with the increase of SOC, the self-discharge rate increased significantly, and the proportion of irreversible self-discharge loss gradually increased, .
You can slow down the self-discharge rate by charging your batteries to only 90-95% of their capacity. You should also protect your batteries from heat, because it will cause them to self-discharge faster. If you want to maximize the lifespan of your lithium-ion batteries.
