Sealed Deep Cycle Battery China
Features of sealed deep cycle storage battery:
The life of sealed deep battery cycle increased by more than 30%
Floating charge life is 8-10 years
Thickened high tin corrosion resistant grid
Wide temperature range: -20°C~55°C
Low self-discharge rate
Excellent sealing and deep circulation battery performance
Good charging receptivity
The adoption of AGM technology, on the one hand, can effectively prevent the electrolyte stratification, thus increasing the cycle life of AGM deep cycle rechargeable battery (can reach 3 times of
ordinary battery) and service life; On the other hand, AGM baffles have better low temperature performance due to their lower resistance.
Advantages of high capacity the best agm battery:
The cycle charging capacity is 3 times higher than that of lead calcium battery, which has a longer service life.
Higher capacitance stability throughout the service life cycle.
More reliable performance at low temperature.
Reduce accident risk and environmental pollution risk (due to 100% sealed acid)
Simple maintenance and reduced deep discharge.
What Factors are Related to The Life of AGM Solar Batteries?
In the photovoltaic solar power station, the component with the shortest life is the battery, but the cost accounts for the largest proportion. What are the main factors related to the life of AGM
solar batteries?
1. Battery charging
In theory, the smaller the charging current, the better. Because the current is low, the smaller the crystals are, the more sufficient the reaction is, and the more electricity it can store.
In the first stage, the battery is charged quickly with the maximum output current of the charger. If it is a solar controller, the battery is charged at the maximum power point of MPPT. The
charging time depends on the battery capacity and the battery state at the beginning of charging. In the second stage, charging is evenly done. In the constant voltage charging stage, the charging
voltage of the charger remains constant, the charging quantity continues to increase, the battery voltage slowly rises, and the charging current drops. In the third stage of floating charge mode,
the battery is basically full, the charging current drops below the floating charge conversion current, and the charging voltage drops to the floating charge voltage.
2. Working environment temperature
High ambient temperature has great influence on the service life of AGM solar batteries. As the temperature rises, battery plate corrosion will increase, and will consume more water, resulting in a
shorter battery life. AGM solar batteries storage in the use of a certain temperature requirements. When a typical AGM solar battery is higher than 25℃, the battery life is halved for every 6 ~ 9℃
increase. Therefore, the floating charging pressure should be compensated according to the temperature, which is generally 2 ~ 4 mV/℃.
In order to achieve the best service life of AGM solar batteries, the operating environment under constant temperature should be created as far as possible, while maintaining good ventilation and
heat dissipation conditions of the batteries. Specifically, rooms with AGM solar batteries should be air-conditioned. The battery should be placed with proper spacing to improve the heat exchange
between the battery and the environmental media. A gap of no less than 15mm should be maintained between the battery and the upper separator. A "air duct" of no less than 150mm should be provided
between the battery and the upper separator to reduce the temperature rise.
3. Discharge depth
Generally speaking, the deeper the daily discharge depth of AGM solar batteries in long-term operation, the shorter the battery life, and the shallower the discharge depth, the longer the battery
life. Shallow cyclic discharge is beneficial to prolong battery life.
There are two obvious advantages to running a deep cycle rechargeable battery in a shallow cycle: first, the battery generally has a long cycle life; Second, batteries often retain more spare
ampere-hour capacity, which makes the PV system's power supply guarantee rate higher. According to the actual operation experience, the more moderate discharge depth is 60% to 70%.
