Safety notes for stocking LiPo / LiIo batteries
• Batteries may only be stored in non completely discharged con-
dition.
• Batteries may only be stored in dry rooms with an ambient tem-
perature of +5°C to +25°C.
• Stock the LiIo/LiPo batteries with a cell voltage of about 3,8V. If
the cell voltage falls below 3 V, then the battery must be neces-
sarily charged. Deep discharge and storage in discharge status
(cell voltage < 3V) make the battery useless.
• Charge and transport your batteries always in a safety bag.
