Lithium batteries can store energy for varying lengths of time, depending on several factors. Generally, lithium batteries have a self-discharge rate, meaning they lose a small amount of their stored energy over time even when not in use. The self-discharge rate of lithium batteries is relatively low compared to other battery chemistries.

The self-discharge rate can be influenced by factors such as temperature, battery chemistry, and the specific design of the battery. In general, lithium-ion batteries (Li-ion) typically have a self-discharge rate of around 1-2% per month. This means that after a year of storage, a Li-ion battery may retain about 80-90% of its charge. Therefore, it is important for battery to have temperature protection and over discharge functions, which can reduce their impact on the battery.

Zlinkwd Energy's lithium battery has good environmental protection and over discharge functions, which can reduce the loss of temperature on the battery and reduce the self discharge rate of the battery.

 

It's important to note that the self-discharge rate is an approximation and can vary among different battery brands and models. Additionally, older or degraded batteries may have a higher self-discharge rate. Zlinkwd Energy's lithium battery all use brand new A-grade cells, with extremely low self discharge rate.

To maximize the storage life of a lithium battery, it is generally recommended to store it in a cool, dry place at around 40% charge. Extreme temperatures, both high and low, can accelerate the self-discharge rate and degrade the battery's performance over time.

It's also worth mentioning that if a lithium battery remains completely discharged for an extended period, it could be at risk of becoming unstable or suffering from irreversible capacity loss. To prevent this, it is recommended to periodically charge the battery if it will not be used for an extended period.
