🔋 What is Thermal Runaway in Lead-Acid Batteries?
Thermal runaway is a dangerous condition where the internal temperature of a lead-acid battery rises uncontrollably, leading to excessive heat generation, potential gas release, and in extreme cases, fire or explosion. This phenomenon typically occurs when the battery』s charging and discharging cycles are not properly controlled, or when ventilation and cooling systems are insufficient.
For industrial users and overseas distributors, understanding thermal runaway is crucial to ensure safety, product reliability, and compliance with international standards.
⚠️ Causes of Thermal Runaway in Lead-Acid Batteries
Several factors can trigger thermal runaway:
- Overcharging – Continuous high charging current generates excessive heat.
- Poor Ventilation – Heat cannot dissipate effectively, causing temperature buildup.
- Internal Short Circuits – Faulty cells or impurities lead to excessive current flow.
- High Ambient Temperatures – Batteries installed in hot, enclosed spaces are at higher risk.
- Improper Maintenance – Lack of regular inspection and cleaning accelerates degradation.
🛡 How to Prevent Thermal Runaway in Lead-Acid Batteries
Manufacturers and system integrators must adopt strict measures to prevent thermal runaway:
- ✅ Use High-Quality Lead Plates and Electrolytes – Ensures stable chemical reactions.
- ✅ Temperature and Voltage Monitoring – Real-time monitoring reduces overheating risks.
- ✅ Proper Ventilation and Cooling Systems – Essential in both rack-mounted and cabinet designs.
- ✅ Advanced BMS (Battery Management System) – Automatically balances voltage and prevents overcharge.
- ✅ Regular Maintenance – Cleaning terminals, checking electrolyte levels, and monitoring capacity.
