The start-stop battery safety valve is typically made of high-temperature and high-pressure resistant materials to ensure that it can withstand the harsh conditions within the battery. Its design pressure is carefully calculated to ensure that it opens at the appropriate pressure level to prevent dangerous overpressure from building up within the battery.

Unlike conventional batteries, start-stop batteries are designed to be repeatedly discharged and recharged during operation. As a result, they produce more gas than conventional batteries, which can lead to a buildup of pressure within the battery. The start-stop battery safety valve is specifically designed to release this excess gas and prevent the battery from becoming overpressurized, which can result in damage to the battery or even a risk of explosion.

Overall, the start-stop battery safety valve plays a critical role in ensuring the safe and reliable operation of start-stop batteries by preventing overpressure and gas buildup within the battery.
