A simple maintenance: gas inside the battery during charging base is absorbed into the electrolyte reduction, basically no electrolyte decreased. 2, holding a liquid electrolyte is absorbed in a high special partition, the flow state is not maintained, so even if the fall can also be used. (Fallen more than 90 degrees can not be used) 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. [3] 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, to prevent the loss, so that 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.
