II. Core Product Features
1. Material and Structural Advantages
·Plate Technology: The plate grid is made of high-tin multi-element lead-calcium alloy, featuring superior electrical conductivity and corrosion resistance; imported graphene is added to the active material as a conductive agent, significantly improving charge-discharge efficiency and cycle life.
·Sealed Design: Adopting a high-temperature curing process combined with a fully sealed structure, it eliminates the need for electrolyte refills during use, produces no acid mist emissions, is corrosion-free and pollution-free, achieving true maintenance-free operation.
·Cycle Performance: Excellent deep-cycle discharge performance with a high number of deep discharge cycles. It accepts 0.2C10 high-current charging, effectively shortening the charging time.
·Environmental Adaptability: Wide operating temperature range, maintaining strong discharge performance even in low-temperature environments to meet demanding working conditions.
2. Safety and Environmental Protection Features
·Built-in safety valve and leak-proof structure to prevent electrolyte leakage and gas expansion risks.
·Complies with environmental protection standards; the battery is recyclable, with no risk of heavy metal pollution.
·Flame-retardant casing and explosion-proof design ensure safe operation under extreme conditions.
III. Main Application Scenarios
Suitable for backup power and energy storage systems in the following fields:
·Telecommunications: Railway communication, mobile communication, and mining communication base stations
·Electric Power: Power substations, wind/photovoltaic energy storage systems
·Commercial & Civilian: UPS uninterruptible power supplies for hospitals, banks, and data centers
·Industrial: Emergency lighting, security systems, and industrial control equipment
IV. Operation Instructions
1. Installation Requirements
·Installation Environment: Well-ventilated, clean, and dry, away from direct sunlight and high-temperature heat sources. The recommended ambient temperature is 20℃~25℃.
·Installation Method: Can be placed upright or horizontally; inversion is strictly prohibited. Maintain a spacing of ≥10mm between battery packs for heat dissipation.
·Wiring Specifications: Securely connect the positive and negative terminals to avoid short circuits. Use insulated tools to prevent electric shock.
2. Charging Specifications
·Standby Use: Charging voltage is 2.27V~2.30V per cell (at 25℃); long-term float charging can extend battery life.
·Cycle Use: Charging voltage is 2.40V~2.45V per cell (at 25℃), with an initial charging current not exceeding 0.2C10 (e.g., ≤100A for 500Ah models).
·Temperature Compensation: For every 1℃ change in ambient temperature, adjust the float/cycle charging voltage by approximately -3mV/℃/cell.
3. Discharge and Maintenance
·Discharge Current: It is recommended not to exceed 0.3C10. Avoid deep over-discharge (a discharge depth >80% will accelerate life degradation).
·Charging Timeliness: The battery must be fully recharged within 24 hours after discharge to prevent plate sulfation.
·Regular Inspection: Inspect the battery pack voltage and connection status every 3~6 months. Clean the terminals to prevent oxidation and corrosion.
·Prohibited Actions: Short-circuiting, disassembling the battery, or disposing of it in fire or water is strictly prohibited.
