What hazard is caused by charging or discharging a battery too quickly?

• A. Short-circuiting
• B. Overheating or out-gassing
• C. Voltage spikes
• D. Absorption of water

Answer: (B)

Charging or discharging a battery too quickly can cause overheating or out-gassing. When a battery is charged at a rate that exceeds its safe limits, the internal chemical processes can become unstable. This rapid reaction generates excessive heat. If the temperature rises too much, it can lead to breakdown of the electrolyte and the release of gases, known as out-gassing. In extreme cases, this can even result in battery swelling, leakage, or bursting, posing safety hazards. Out-gassing especially occurs in sealed lead-acid batteries and lithium-ion batteries, and it can be accompanied by toxic fumes. Proper charging and discharging rates are crucial for maintaining battery health, ensuring safety, and prolonging battery life. Understanding the limits of battery specifications is essential for safe operation and handling.
