Storing lithium-ion batteries safely is crucial due to the risk of fire and explosion, potential damage from extreme temperatures, mechanical harm, exposure to moisture, unintentional activation, and the need to prolong battery life.

By storing batteries in controlled environments, protecting them from physical damage, minimizing contact with moisture, preventing accidental short circuits, and following recommended guidelines, you can mitigate risks and ensure the batteries' safety, longevity, and performance.

To safely store lithium-ion batteries, follow these guidelines:
  • Temperature

    Store lithium-ion batteries in a cool, dry place. Avoid exposing them to high temperatures or direct sunlight, as extreme heat can cause damage or shorten their lifespan. The recommended temperature range for storage is usually between 17°C to 30°C (62°F to 86°F).
  • Charge level

    If you plan to store lithium-ion batteries for an extended period, it's best to store them with a charge level between 40% and 60%. This charge level helps to maintain the battery's capacity without stressing it too much. Avoid storing batteries fully charged or completely discharged, as this can lead to degradation or potential safety hazards. We advise to charge your batteries every 3-6 months from purchase of the battery.
  • Battery protection

    Ensure that the battery terminals are protected from contact with metal objects or other batteries during storage. Exposed terminals can cause short circuits, leading to safety risks or discharge of the battery.
  • Storage

    Lithium-ion batteries do experience a gradual capacity loss over time, even when not in use. On average, they can lose about 2-3% of their capacity per month due to self-discharge. However, it's important to note that this is just an average and can vary based on the specific battery chemistry, quality, and storage conditions.

    Temperature also plays a significant role in battery degradation. For every 10-degree Celsius increase in temperature, the capacity loss can double. Therefore, it's crucial to store lithium-ion batteries in a cool and stable environment to minimize the impact of self-discharge and prolong their overall lifespan. Regularly charging the batteries, even if they are not in use, can help maintain their overall health and extend their lifespan.

    However, it's worth noting that lithium-ion batteries should not be stored fully charged for long periods, as this can also have a negative impact on their longevity. Ideally, they should be stored at a charge level between 40-60% for extended storage periods. This range helps to strike a balance between minimizing self-discharge and avoiding overcharging, which can be detrimental to the battery's health.

  • Packaging

    If you need to store lithium-ion batteries for an extended period or transport them, consider using the original packaging they came in or invest in specialized battery storage cases. These cases provide insulation, protection, and often have built-in safety features.
  • Separation

    Store lithium-ion batteries individually or keep them in separate compartments if storing multiple batteries. This prevents contact between terminals and reduces the risk of short circuits.
  • Avoid extreme environments

    Do not store lithium-ion batteries in humid or excessively cold environments. High humidity can lead to corrosion, while freezing temperatures can damage the battery's internal components.
  • Regular checks

    Periodically check the stored batteries for any signs of damage, leakage, or swelling. If you notice any abnormalities, do not use or store the battery further and dispose of it properly following the relevant recycling or disposal guidelines for your area.
