Under what circumstances can a battery self-ignite?
1 Answers
A battery can self-ignite when it is charged and there is a short circuit between the positive and negative terminals. The following are situations where a battery may catch fire: 1. Avoid contact with metal containers: Do not allow the battery to come into direct contact with metal containers. Acid-proof and heat-resistant materials should be used instead, otherwise it may cause smoking or burning. 2. Charger: Use the designated charger under specified conditions for charging, otherwise it may cause the battery to overheat, vent, leak, burn, or rupture. When using more than one battery in an application, ensure that the connections between the batteries are correct and that the connections to the charger or load are correct, otherwise it may cause the battery to rupture, burn, or be damaged. 3. Environmental conditions: Do not install the battery in a sealed device, as this may cause the device to rupture. When using the battery in medical equipment, install a backup power source in addition to the main power source, otherwise power failure may cause harm. Do not place the battery near a heat source (such as a transformer), as this may cause the battery to overheat, leak, burn, or rupture.
