How do you store the battery correctly (e.g. over winter)?

For optimal battery life, the battery should be stored at a temperature of 10°C to 25°C and a humidity of 20% to 75%. Ideally, the battery should be kept at about 75% charge. If the battery is stored for too long at a low charge, the voltage inside the battery will drop so dramatically that a deep discharge can occur, permanently damaging the battery. To wake up the battery from sleep mode after a long period of inactivity (2 weeks), press the button above the USB charging port.
