YUASA Yuasa Battery 12-38 models offer no free acid, the battery can rewind 90 degrees safely. Electrolyte specific gravity low and prolong life. Strict selection and advanced manufacturing process, so that the self-discharge is minimal. Low float current, lifetime guarantee. The reactor was sealed high efficiency. Gas inside the battery at 5 years 1. simple maintenance charge reduced basic absorbed electrolyte, basically no electrolyte reduction: life. 2. hold liquid electrolyte is absorbed in a high special partition, remain scrolling state, so even if the fall can also be used. 3. superior safety performance due to extreme overcharge operation errors caused by too much gas can be released to prevent rupture of the battery. 4. Minimal self-discharge with a special lead-calcium alloy production grid, the self-discharge to a minimum. 5. Long life, the economy is good battery grid corrosion resistant 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, it is a long life battery economy. 6. The internal resistance due to the resistance of small, high-current discharge characteristics. 7. excellent deep discharge recovery capabilities in case of long-term discharge, as long as the full charge, basically does not appear to reduce capacity, can be restored quickly. NP Series (general applications) Features: There are a variety of cell types to choose from, in order to ensure that the needs of various battery capacity.
