UPS back-up systems Inverter back-up systems Industrial back-up systems Small wind and solar applications. More than 260 cycles at 80% discharge in cycle service. Terminals are LHP (Looks like a threaded bolt.) It uses specially alloyed calcium-lead, which ensures extremely low levels of 'electrolyte decrease'. Therefore there is no need to supplement distilled water if the charging system remains error-free. Special liquid-gas separators keep the electrolyte inside. These separators are also used between the positive and negative plates of a lead-acid battery to prevent a short circuit through physical contact. Its unique wrought lead-calcium grid design means less internal corrosion and efficient current conductivity for more power and longer life. It also cuts gassing, resists over-charge, heat and thermal runaway. Terminal Layout Type: LHP (Centre) Flame Arrestor: Prevents outside spark from causing explosions Hydrometer: In a typical situation when the specific gravity drops to 1,100, the battery is fully discharged. Heat Sealed Covers: Prevents leakage and contamination. Exclusive Patented Liquid Gas Separator: Prevents Electrolyte loss by collecting and returning liquid to the reservoir. Heat Sealed Covers: Prevents leakage and contamination. Centred Cast-on Plate Straps: Stronger than the thinner gas-burned conventional connectors. Wrought Lead-Calcium Grids: Overcharge resistance. Less self-discharge. Low-Resistance Envelope Separators: Improve vibration durability. Polypropylene Case: Lightweight and easy to handle
