Long service life: Utilizes high-strength tight assembly technology to prevent active material shedding; employs high-specific gravity electrolyte to enhance charge acceptance and deep discharge cycle capability; increased acid volume design avoids shortened lifespan due to electrolyte depletion, with a normal float charge design life of over 8 years (at 25°C). Excellent high-rate discharge: Tight assembly process minimizes internal resistance, providing superior high-current discharge characteristics, improving by more than 20% compared to conventional batteries. Low self-discharge: High-purity raw materials and special manufacturing processes result in minimal self-discharge. Can be stored at room temperature for six months without recharging, with a self-discharge rate of less than 3% per month. Easy maintenance: Special oxygen absorption cycle design overcomes electrolyte water loss during charging, maintaining almost constant water content in the electrolyte during use, eliminating the need for water replenishment. High safety: Equipped with a specialized safety valve that effectively isolates external sparks and prevents internal battery incidents. Simple installation: Can be installed vertically, horizontally, or stacked, requiring minimal space and offering flexibility and convenience. Clean and environmentally friendly: Produces no acid mist during use, causing no corrosion to surrounding environments or equipment. Can be directly installed in offices or equipment rooms without anti-corrosion treatment. Wide operating temperature range: Operates effectively from -20°C to +45°C. Charging method: Constant voltage current-limited charging is recommended, with a charging current of 0.25C20 amperes (at 25°C). High capacity retention rate: Over 97% per month (at 25°C). Case material: Made of ABS material, with flame-retardant ABS available as an option. This battery has a wide range of applications, including UPS/EPS power supplies, DC screens, photovoltaic energy storage, solar street lights, wind energy storage, substations, and is suitable for use in power plants, base stations, industrial, financial, medical, transportation, equipment rooms, data centers, and other locations.
