Lithium primary batteries demonstrate an impressively low self-discharge rate, allowing them to be stored for up to 3 years. To further enhance their performance, it is advisable to store these batteries in refrigerated conditions. By opting for a cold storage environment, the longevity and effectiveness of lithium primary batteries can be significantly improved.
Due to their low self-discharge rate, lithium-ion batteries have the capability to be stored for over six months at a temperature of 20°C. Moreover, when retrieved, most of their capacity can be restored.
It is crucial to take into consideration the self-discharge phenomenon in lithium batteries. In the event that the battery voltage remains below 3.6V for an extended period, it can lead to an over-discharge situation, ultimately damaging the internal structure of the battery and shortening its lifespan. Consequently, it is advisable to recharge lithium batteries every 3 to 6 months when they are kept in long-term storage. Ideally, the voltage should be charged to around 3.8 to 3.9V, with the optimum storage voltage being approximately 3.85V. It is important to note that fully charging the batteries is not recommended in these storage scenarios.
Lithium batteries exhibit a broad temperature range for their usage, allowing them to be utilized outdoors even in the frigid winters of the northern regions. Nonetheless, it is important to note that during such cold conditions, their capacity might decrease significantly. However, once these batteries are brought back to room temperature, their capacity can be effectively restored.
Precautions
The lithium primary battery is quite different from lithium-ion batteries as it lacks the ability to be charged and poses a significant danger if attempted to charge. Nevertheless, it shares similar precautions with lithium-ion batteries that need to be followed for safe usage.
