12V 120AH deep cycle battery

deep cycle battery12V 120Ah Kweight batteris is dedicated to provide high quality and reliability deep cycle battery. 12V 120AH 10HR 406mm*174mm*233mm Applications: Alarm System, Medical Equipment Cable Television, UPS Communication Equipment, Power tools Control Equipment, Emergency Power System Security System, Toys 1. Good discharging performance: With smooth discharging voltage and mild discharging platform. 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. 3. 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%. 4. 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. 5. 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. 6. 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%.
