• Avoid frequent use at high temperatures because this can reduce performance.
• Use a dry location at or near room temperature when storing the power module for an
extended time. Prolonged storage at higher temperatures can reduce performance.
• Ensure the remaining charge level is at or near mid-capacity when storing for an
extended time. The remaining charge will slowly drain during storage. Periodically
charge the power module to ensure the remaining charge does not drain to low levels.
