OLAND battery sales service hotline: 010-56251281,13366215788 online customer QQ2522025723 1, maintenance is simple: gas generated inside the battery during charging substantially reduced absorption of electrolyte, basically no electrolyte decreased. 2, holding a liquid electrolyte is absorbed in a high special partition, the flow state is not maintained. 3, superior safety performance: When operational errors due to extreme overcharge caused by too much gas can be released to prevent rupture of the battery. 4, self-discharge small: with a special lead-calcium alloy production grid, the self-discharge to a minimum. 5, long life (design life of 3 to 6 years) the economy is good: The battery grid using good corrosion resistance special lead-calcium alloy, while using special separators can keep the electrolyte, and then pressed at the same time with a strong positive plate active material prevent the loss, it is a long life, economical battery. 6, the internal resistance: Due to the small resistance, good high-current discharge characteristics. 7, after deep discharge has excellent resilience: in case of long-term discharge, as long as the full charge, basically does not appear to reduce capacity, can be restored quickly. & Highly reliable pole double seal structure, its shock resistance and sealing performance is greatly improved, to ensure that the electrolyte is not leaking, improve the reliability of the product. Wind and solar power system solutions are easy establishment, applicable solar and wind resource-rich regions. By scenery complementary resources that can maximize the use of energy, expand network coverage. In maintenance, monitoring and protection can be fully solar controller by using voltage control theory, the effective protection of the battery and load equipment and other systems, thereby reducing the amount of base maintenance. This program area adaptability, environmental adaptability, solar controller can be -30 ℃ ~ 60 ℃, the hydrogen fuel cell can be -40 ℃ ~ 60 ℃ temperature range of applications, and is capable of hurricanes, hail and other inclement weather Under normal operation. In addition, both the energy can be flexibly configured according to the conditions, but through the improvement of the charge and discharge management solution that can maximize battery life, and to safeguard stability of the system, reducing the system investment.
