Do not leave a fully charged battery connected to a charger since overcharging may shorten battery lifetime. If left unused, a fully charged battery will lose power over time. Leaving the device in hot or cold places, such as in closed car in summer or winter, will reduce the capacity and lifetime of the battery. You should always try to keep the battery between 15 °C and 25 °C. Battery performance is particularly limited in temperatures well below freezing. Do not dispose of batteries in a fire as they may explode. Batteries may also explode if damaged.
