Battery shelf life when
charge is not maintained Ideally internal and external batteries should be stored in a cool, dry place. If the batteries
are stored
without maintaining charge, typical shelf life is as follows:
• At 0 to 20 °C (32 to 68 °F): 12 months
• At 21 to 30 °C (69 to 86 °F): 9 months
• At 31 to 40 °C (87 to 104 °F): 5 months
• At 41 to 50 °C (105 to 122 °F): 2.5 months
NOTE:
• If you plan to store the ventilator for longer than 6 months, remove batteries before
storage. Replace the batteries before using the ventilator again.
• Battery life specifications are approximate. To ensure maximum battery life, maintain
full charge and minimize the number of complete discharges.
