Basic Information
Model: DJ400.
Type: Maintenance-free valve-regulated sealed lead-acid battery 1.
Rated Voltage: 2V 4.
Rated Capacity: 400Ah 4.
Product Features
Maintenance-free 1: Adopts a special design to overcome the electrolytic water loss during battery charging. The volume and specific gravity of the electrolyte remain almost unchanged during use, no water replenishment is required at all, and maintenance is simple.
Sealed and safe 1: There is no flowing electrolyte inside, it can be installed vertically or sideways, no leakage, no acid mist is generated during normal charging, and it can be installed in ordinary rooms, reducing project costs.
Long service life: Adopts lead-calcium alloy grids with good corrosion resistance. Under 25℃ environment, the normal floating charge life can reach more than 10 years 1.
Excellent high-power discharge performance 1: Adopts high-quality plates with small internal resistance and glass fiber separators, tight assembly, and extremely low internal resistance. It discharges with high current in the temperature range of -40℃~60℃, and the output power is about 15% higher than that of conventional batteries.
Easy to install and use 1: The battery is fully charged when leaving the factory, and users can install and use it directly after receiving it.
Low self-discharge rate: Adopts a special lead-calcium alloy formula, with extremely low self-discharge rate. After standing for 28 days at 25℃ room temperature, the self-discharge rate is less than 1.8% 5.
Safe and reliable 5: Adopts double sealing design of battery tank cover and terminal posts to prevent acid leakage. The safety valve can prevent external gas and dust from entering. At the same time, it is equipped with a safe and reliable explosion-proof exhaust system to eliminate the bulging of the battery shell caused by excessive pressure.
Technical Parameters
Charging Voltage: At 25℃, the floating 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 Range 5: Charging temperature 0℃-40℃, discharging temperature -20℃-55℃, storage temperature -15℃-50℃.
Application Scope 5
Suitable for multi-purpose backup and energy storage power supplies, such as uninterruptible power supplies, electronic energy systems, emergency backup power supplies, railway signals, aviation signals, security systems, electronic instruments and equipment, communication system power supplies, DC power supplies, automatic control systems, etc.
