Basic Information
Model: DJ400.
Type: Maintenance-free Valve-regulated Sealed Lead-acid Battery¹.
Rated Voltage: 2V4.
Rated Capacity: 400Ah⁴.
Product Features
Maintenance-free¹: Adopts a special design that overcomes the phenomenon of electrolyte water loss during battery charging. During use, the volume and specific gravity of the electrolyte remain almost unchanged, requiring no water replenishment at all, and maintenance is simple.
Sealed and Safe¹: No flowing electrolyte inside, can be installed vertically or horizontally, no leakage, no acid mist generated during normal charging, can be installed in ordinary rooms, reducing engineering costs.
Long Service Life: Uses lead-calcium alloy grids with good corrosion resistance. At 25℃, the normal float charge life can reach more than 10 years¹.
Excellent High-power Discharge Performance¹: Uses high-quality plates with small internal resistance and fiberglass separators, with tight assembly and extremely small internal resistance. Within the temperature range of -40℃ to 60℃, when discharging at high current, the output power is about 15% higher than that of conventional batteries.
Easy to Install and Use¹: The battery is fully charged when leaving the factory, and users can directly install and use it after receiving it.
Low Self-discharge Rate: Uses a special lead-calcium alloy formula, with an extremely low self-discharge rate. When left standing at 25℃ room temperature for 28 days, the self-discharge rate is less than 1.8%⁵.
Safe and Reliable⁵: Adopts a double-seal design for the battery槽盖 (battery cover) and terminals to prevent acid leakage. The safety valve prevents external gas and dust from entering. At the same time, it has a safe and reliable explosion-proof exhaust system, eliminating the phenomenon of battery casing expansion caused by excessive pressure.
Technical Parameters
Charging Voltage: At 25℃, the float charge voltage is generally 2.23V-2.27V, and the equalization charge voltage is usually 2.30V-2.35V.
Charging Current: The recommended charging current is 10%-20% of the C10 capacity, that is, 40A-80A.
Operating Temperature Range⁵: Charging temperature 0℃-40℃, discharging temperature -20℃-55℃, storage temperature -15℃-50℃.
Application Scope⁵
Suitable for multi-purpose standby and energy storage power sources, such as uninterruptible power supplies, electronic energy systems, emergency standby power sources, railway signals, aviation signals, security systems, electronic devices and equipment, communication system power sources, DC power sources, automatic control systems, etc.
