deep cycle battery 12V 120Ah

deep cycle battery 12V 120Ah Kweight battery co., ltd is dedicated to provide high quality and reliability deep cycle battery. Construction: Component Raw material Positive Lead dioxide Negative Lead ContainerABS Cover ABS Sealant Epoxy Resin Safety valve EPDR Terminal Copper Separator Fiber glass Electrolyte Sulfuric acid Deep cycle General Features: Sealed and maintenance free operation. Non-Spillable construction design. ABS containers and covers(UL94HB, UL94-0)optional. Safety valve installation for explosion proof. High quality and high reliability. Exceptional deep discharge recovery performance. Low self discharge characteristic. Flexibility design for multiple install positions. This battery is functional and safe. It is valve regulated which makes it nearly impossible to spill, and with its tightly sealed construction, it can be operated from any angle. With its hard plastic case, it can take severe amounts of high impact and not do any damage. It even has a low pressure safety release valve. This battery will last long time both physically and chemically. 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%.
