VRLA gel battery 12V 80Ah

VRLA gel battery 12V 80Ah kweight battery ltd. is dedicated to provide high quantlity and reliability VRLA gel battery 12V 80Ah for our clients around the world. Construction: Component……Raw material Positive………..Lead dioxide Negative……….Lead Container……..ABS Cover………….ABS Sealant………..Epoxy Resin Safety valve…..EPDR Terminal………Copper Separator……..Fiber glass Electrolyte……Sulfuric acid the sealed maintenance-free battery don’t need to check liquid amount and additional water.the sealing label should not be removed within service period.the positive electrode was market with “+” or red color, the negative electrode was marked with “-” or black color.the connection should be right electrode, and fasten with connection parts, otherwise, battery might be burned due to wrong connection.if battery unused for long time, pls charge power fully, then put in dry place, the battery should recharge with constant pressure and limit current after 6 months. Characteristics of sealed lead acid battery: Excellent safety performance: No electrolyte leakage, battery swelling and cracking under normal use.Good discharging performance: With smooth discharging voltage and mild discharging platform.Good shock-proof performance: The fully charged and completely fixed battery, with 4mm amplitude and 16.7Hz frequency do have a normal open circuit voltage without leakage, batteries swelling or cracking problem after one-hour vibration.Good resistance to over discharge: In temperature of 25 degrees Celsius, the fully charged battery discharges with fixed resistance which is equivalent to the one required by 1 CA discharge of the battery for three weeks, and it can restore capacity over 75%.Good impact-proof performance: The fully charged battery is proved to maintain normal open circuit voltage and be without leakage or batteries swelling or cracking after dropping three times from 20cm height naturally to a 1 cm-thick hardwood board.Good resistance to high current: The fully charged battery is proved to be without conductive part melted or any appearance deformation after discharging at 2 CA for minutes or 10 CA for % seconds.Good resistance to overcharge: The fully charged battery is proved to maintain normal open circuit and be without leakage or batteries swelling or cracking in temperature of 25 degrees Celsius after charging at 0.1CA for 48 hours, and the capacity maintain over 95%.
