The boost is designed to retain 70% of their charge for up to one year. If the Boost was never opened and fully charged, or if it sits without charge or is stored outside of the recommended temperature range for long periods, this can damage or weaken the internal battery. We recommend checking the boost periodically and recharging it as needed so it is ready to use when needed.
