Battery Structure

  •     Container/Cover: Made of UL94HB and LU 94V-0 ABS Plastic
  •       Negative Plates: Use the special PbCa alloy grids, optimize the recombination efficiency and less gassing.
  •        Separator: Import high quality AGM separator.
  •      Positive Plates: PbCa grids minimize corrosion and prolong life.
  •        Terminal post: Cooper material with maximum conductivity, enhance the high current rapidly.
  •    Vent Valve: Allows the release of excess gas automatically for safety.

 

Application

Control systems, Electric toys, Emergency lamp, Power tools, Medical treatment equipment, Alarm system, Emergency light system, Standby power supply, UPS and computer standby power supply, Power system, Telecommunication system, Firefighting equipment standby power supply, Railway station, Ship Equipment, Military Equipment, Telephone switching system.

 

Characteristics

  •    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 stock-proof performance: The fully charged and completely fixed battery, with 4mm amplitude and 16.7HZ frequency does have a normal open circuit voltage without leakage, batteries swelling or cracking problem after one-hour vibration.
  •        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 1cm-thick hard woodboard.
  •        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 1CA discharge of the battery for three weeks, and it can restore capacity over 75%.
  •     Good resistance to overcharge: The fully charged battery is proved to maintain normal open circuit voltage 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%.
  •       Good resistance to high current: The fully charged battery is proved to be without conductive part melted or any appearance deformation after discharging at 2CA for 5 minutes or 10CA for 5 seconds.
