DKGB2-1000-2V1000AH SEALED GEL LEAD ACID BATTERY
Technical Features
1. Charging efficiency: The usage of imported low resistance raw materials and advanced process help make theinternal resistance smaller and the acceptance ability of small current charging stronger.
2. High and low temperature tolerance: Wide temperature range (lead-acid:-25-50 C ,and gel:-35-60 C), suitablefor indoor and outdoor use in varies environments.
3. Long cycle-life: The design life of lead acid and gel series reach to more than 15 and 18 years respectively, forthe arid is corrosion- resistant. and electrolvte is without risk of stratification by using multiple rare-earth alloy ofindependent intellectual property rights, nanoscale fumed silica imported from Germany as base materials, andelectrolyte of nanometer colloid all by independent research and development.
4. Environment-friendly: Cadmium (Cd), which is poisonous and not easy to recycle, does not exist. Acid leakageof gel electrolvte will not happen. The battery operates in safety and environmental protection.
5. Recovery performance: The adoption of special alloys and lead paste formulations make a low self-dischargerate, good deep discharge tolerance, and strong recover capability.

Characteristics of VRLA battery (Valve Regulated Lead Acid Battery)for photovoltaic power generation system
Working mode of storage battery for photovoltaic power generation system
The working mode of the battery can be divided into two types: recycling and floating charging. Frequently in the state of frequent charging and discharging, that is, recycling; It is used for floating charge when it is often in the charging state, which can compensate for the capacity loss of the battery due to self discharge. VRLA battery for photovoltaic power generation system belongs to recycling mode.
Charging and discharging characteristics of storage battery for photovoltaic system
The charging and discharging characteristics of storage battery for photovoltaic power generation system generally have four points:
(1) Charging during the day, discharging at night and in cloudy and rainy days;
(2) The charging rate is low, and the average charging current is generally 0.01~0.02C, rarely 0.1~0.2C;
(3) The discharge current is small, and the discharge rate is usually 0.004~0.05C;
(4) The charging time is short, even if it is only about 10 h for a long time. The photovoltaic system can rarely fully and rapidly charge the battery, and the battery is often in an undercharged state.
Performance requirements of VRLA battery for photovoltaic power generation system
Photovoltaic power generation systems are mostly built in remote mountains, plateaus and Gobi. The natural environment is very harsh, and the working environment temperature varies widely. Therefore, there are the following requirements for the batteries in the photovoltaic power generation system:
(1) With deep cycle discharge performance and long charge discharge cycle life;
(2) Strong overcharge resistance;
(3) Strong capacity recovery after over discharge;
(4) Good charging acceptance;
(5) When the battery is used in a static environment, the electrolyte is not easy to delaminate;
(6) Maintenance free or less maintenance performance;
(7) It shall have good high and low temperature charging and discharging characteristics;
(8) It can adapt to the use environment in high altitude areas;
(9) All batteries in the battery pack are in good consistency.
