Batteries naturally discharge over time, and prolonged storage should be avoided to maintain optimal performance. For guidance on battery storage, please refer to the following FAQ: How to store batteries?

If batteries have been stored for an extended period, it's recommended to conduct a battery load test to verify their initial state. Ensure that the appropriate load is as per the instrument's specifications.

Storage Guidelines for Lithium-ion (rechargeable) Batteries:

• Store in a dry location at temperatures preferably not exceeding 30°C.
• For long-term storage, maintain the battery within a state of charge between 15% and 45% to optimize lifespan.
• Perform periodic checks to prevent complete discharge, which can negatively impact battery health.

Shelf Life:

• Alkaline and Lithium-ion batteries have a shelf life of 4 years from the production date.
• Lithium batteries can be stored for up to 7 years from the production date.

By following these guidelines, you can help preserve battery life and ensure optimal performance when needed.
