How to Store Lithium Batteries

How to Store Lithium Batteries

Lithium batteries are currently making a wave in technology to replace the way we power devices and equipment. Lithium battery chemistry is the newest technology among small and large corporations alike, offering a longer lifespan than conventional batteries, and providing end users with a lightweight design.

Although lithium batteries offer advantages for the end-user, they still must be tested to ensure quality. Storage buildings are used to store bulk-quantities of lithium batteries at certain temperatures to ensure a safe storage environment.

Lithium Battery Storage Temperatures

The recommended storage temperature for most lithium batteries is 59°F. Some lithium batteries must be stored at different storage temperatures, so before storing, it is important to thoroughly read labels on proper storage. Lead acid must always be kept at a full charge during storage, while nickel and lithium batteries should be stored at around 40% state of charge.

If improper storage occurs, lithium batteries might become unstable, causing excessive heat to cause damage internally and potentially catch on fire. Cells should be stored with a charge between 30% and 50%. The cells can be stored fully discharged, although the cell voltage should not drop below 2.0 The maximum voltage should not exceed 4.1 volts.

Always follow charging instructions provided with each lithium battery.

Battery Storage Maintenance

  • Monitor battery charge status while charging
  • Ensure temperature controls are set to specified temperatures
  • Observe run time with a full-charged battery
  • Ensure batteries self-discharge
  • Check batteries before placing in storage for irregularities in charge status

Handling Precautions

  • Avoid exposing lithium batteries to excessive vibration
  • Do not keep batteries in high or low temperatures
  • Always handle batteries with caution
  • Place batteries in storage after the building reaches compliant temperature levels
  • Do not use damaged batteries
  • In case of contact with fluid do not rub eyes. Immediately flush eyes
  • Wash hands after handling batteries
  • In the event of contact on clothing, change clothing immediately

How To Store

The hazards associated with lithium batteries present challenges to manufacturers and industries who store these powerful energy tools. Find out about lithium battery hazards and learn about the benefits of a safe lithium battery storage building here.

Lithium Battery Storage Buildings

There are a number of different storage lockers from US Chemical Storage, designed to safely store lithium batteries. Non-fire rated designs offer lithium batteries to be stored outside of facilities, while fire-rated lithium storage buildings are designed to be stored near facilities or even inside facilities to provide efficient manufacturing operations. Lithium battery storage buildings should always be equipped with a fire suppression system, climate control, mechanical ventilation, fiberglass grated flooring as well as a variety of doors for exit and entry.

  • Fire-Rating                                                        Distance from Occupied Facilities or Property Lines
  • Four hour fire-rated:                                                            Less than 10 feet or within an existing structure.
  • Two hour fire-rated:                                                             10 to 30 feet.
  • Non-Combustible (no fire rating):                                     Greater than 30 feet.
