Use your YEVO in temperatures between 0º and 45º C (32º to 113º F). Using your product outside this temperature range can alter the battery performance and lead to malfunction or permanent damage of components inside it. An ambient temperature below 0º C (32º F) may temporarily shorten battery life.
Higher temperatures than 30º C (86º F) may also alter the battery performance. Avoid exposing your YEVO to extreme heat e.g. leaving it in your car on a hot summer day, exposing it to direct sunlight over an extended period of time etc. as this may damage the battery or other components inside.
Please note that storage temperatures should never get below -10°C (14°F) or exceed 60 °C (140°F) as this may cause critical damage to both battery and other components.
