The valve-regulated sealed lead-acid battery (VRLA battery) is the most widely used and adaptable dedicated energy storage power supply in the rail transit field.
Product Features
Apply unique labyrinth type pole column structure and multiple sealing technology, sealing is reliable.
Apply lean solution design, oxygen circulation compound ability is excellent, sealing effect efficiency is high.
Special corrosion resistant rich tin and poor calcium grid alloy, single polar plate applies large capacity and long life design, specific energy of battery is high.
Apply raw material, electrolyte and additive with high purity, self-discharge rate is low.
Apply flame retardant ABS shell, strength of shell is good, impact resistance, thermal resistant complies with requirements of GB2408-2008.
Apply compound ultra fine glass fibre partition, its inner resistance is low, high ratio discharge performance is good.
Apply special additive formulation and electrolyte formulation, utilization ratio of active material is high, charging acceptance capability is strong, with good recovery performance after deep discharging.
Advantages
·Long Service:
LifeAdopts corrosion-resistant lead-calcium alloy grids & special separators; based on VRLA tech, it has a 15+ year design life (25°C) (avoids electrolyte loss & active material shedding).
·Easy Maintenance:
Oxygen from float charging is reduced to electrolyte (no loss), so no need to measure electrolyte gravity or refill water. ·Excellent High-Rate Discharge:
High-porosity separators + integrated terminals lower internal resistance; 1-minute discharge is 20% better than traditional flooded batteries.
·Space-Saving:
Horizontal InstallationSeparator-retained electrolyte (no leakage) allows horizontal use; compact design + front-side wiring cuts occupied space.
·Cost-Effective:
No refilling/equalizing charging (cuts costs); no acid fumes (no acid-resistant treatment for adjacent equipment).
·High Safety:
Equipped with a safety valve (controls gas buildup) and explosion-proof filter (blocks spark ignition).
·Low Self-Discharge:
Special lead-calcium alloy grids minimize self-discharge for long-term storage.
