12V 44Ah rechargeable storage battery AGM lead battery for UPS photovoltaic system
Deep Cycle Maintenance Free AGM Type VRLA SLA Battery 12v 44ah for off-grid solar system, wind, photovoltaic, solar panel / inverter, power plant, UPS, emergency lighting, Solar Street Light, renewable energy, Data Center, Medical Equipment , etc
Introduction of ML series
Sunstone ML series vrla battery is designed for 10 years life. For this long life purpose, the plate are made by developed alloy which is more effectual for preventing corrosion. At the same time, we also according the percentage of alloy change the outlook and dimension of grid wire. It will give batteries more effective radius for chemical reaction. For this long life design life battery, new features include handles for easy lifting, copper terminals for higher current capacity and reduced damaged during transportation, designed to comply with EUROBAT ( draft IEC 896-2), IEEE, JIS and BS 6290 Part4 certified components.
