Product Strengths
Maintenance-Free & Leak-Proof Design: Fully sealed valve-regulated structure with glass fiber separators supports vertical and 90° tilted installation. High-efficiency oxygen recombination technology eliminates gas precipitation, requiring no routine water refilling or daily maintenance.
Stable & Powerful Discharge Performance: Optimized high-purity lead alloy plates reduce internal resistance, enabling strong high-current discharge capacity for instant heavy-load startup and frequent deep cycle discharge.
Low Self-Discharge & Long Endurance: Premium raw material formula suppresses self-discharge efficiently. With monthly power loss below 3%, the battery maintains sufficient power after 6 months of idle storage.
High Safety & Wide Environment Adaptability: Built-in one-way explosion-proof safety valve automatically releases excessive internal pressure. Durable flame-retardant ABS shell resists impact, corrosion and aging, operating stably in -20℃ to 60℃ temperature range.
High Consistency & Flexible Networking: Strict production control ensures outstanding battery consistency. Supports series and parallel combination to build 24V, 48V, 96V and other customized energy storage systems.
Application Range
Photovoltaic Energy Storage: Off-grid solar systems, solar street lights, residential and commercial solar backup power
Power & Communication: UPS/EPS power supply, communication base stations, power distribution cabinets, railway signal backup power
Security & Emergency: Fire emergency lighting, security alarm and monitoring systems, building emergency power supply
Special Scenarios: RV energy storage, marine backup power, medical equipment standby power, outdoor high-power energy storage devices
Operation & Maintenance Guidelines
Optimal working temperature: 20℃-25℃. Extreme high or low temperature will affect battery service life and capacity.
Supplement charging every 3-6 months during long-term storage to prevent plate sulfation.
Prohibit overcharging, overdischarging and short circuit; use matched intelligent charger to extend battery life.
Adopt batteries of the same batch and specification for grouped connection to ensure system stability.
Quality & Service Guarantee
This battery passes ISO9001 quality system certification and flame retardant safety certification, complying with international industrial standards. All products undergo strict full inspection before delivery to ensure stable quality. We support OEM customization and provide standardized warranty services and professional technical support, delivering high-cost-performance power solutions for global energy storage and backup power projects.
