VRLA Series

OPERATING GUIDELINES FOR SMF / VRLA BATTERIES

  Constant voltage current limited charging as per the charging specification table – 3 for optimum performance / life.
  For operating temperature more or less 25°C, apply the correction factor for charging voltage as per as the table given below.
  Immediate recharging recommended after discharge to avoid battery capacity loss.
  For deep discharging application re-charging time to be increased by 1.5 to 2 times for the normal charging (On float 24 hrs and On boost 16 hrs charging) time before it undergoes next cycle.
  Never use new and old batteries in series. Batteries of different capacities and different manufacturer should never be used in same bank, Parallel string not recommended. Avoid bypassing the lower cutoff protection which will allow the battery to go into deep discharge.
  Continuous boost charging is not recommended for more than 24 hours to avoid over charging.
  Replace any defective if abnormalities noticed on voltage, heat, electrolyte leakage or physical deformation.
  If the battery is stored more than 03 months, boost charging for 09 hours recommended before the battery is put in deformation.
  Once in 06 month the batteries should be equalization charge at 13.8 volts per modules.
  Do not reverse charge the battery.
  Never bend the terminals not solder directly.
  Use proper size connector for the inter connection and end connection. Avoid loose/bad connection.
  Battery shall be secured against impact, vibration and heat source.
  Keep top of the battery clean and dry.
  Do not short the terminal directly.
  Transport the battery in the upright position.

Caution

  Keep the battery away from sparks, cigarettes and open flame.
  Avoid the metallic contact across the terminal.
  In case of acid leakages due to container crack, do wash it with water immediately.
  Do not install the battery without removing the packing cover.
  Avoid charging in air tight container.

ADVANTAGES & FEATURES

  High quality and reliability : The tough value of these rechargeable batteries is designed to provide excellent performance. These can withstand overcharge, over discharge, and resisting vibration and shock. Before the dispatch of the products, these are GOLD STAR tests each battery thoroughly based on various parameters including 100% High rate discharge test.
  Exceptional deep Discharge recovery : GOLD STAR SMF VRLA batteries have exceptional discharge recovery, even after deep or prolonged discharge.
  No corrosive gas generation : The batteries are sealed properly by ultra sonic method, so that there is no corrosive gas generated during normal usage.
  Long service life : Gold Star Power Limited based on unique grid technology, allow composition, correct AGM compression and specially designed for standby use. Thus, these ensure to provide long services life.
  Maintenance- free operation : The batteries are know for their maintenance free operation, wherein there is no need to check the specific gravity of the electrolyte or to add water during the service.
