Lead-Acid Battery Advantages
Extreme Temperature Adaptation
-20℃~50℃ operational range maintains 85% capacity in mining environments where lithium batteries suffer performance degradation
Reduced Maintenance Complexity
Integrated water-refilling ports and accessible cells enable on-site maintenance without specialized tools or training
Cost-Effective Power Solution
40% lower initial investment vs lithium systems with 2,000+ charge cycles at 70% capacity retention
Safety-Enhanced Design
Zero thermal runaway risk with lead-acid chemistry, certified for use in methane-rich mining environments
