This mercury 200AH Gel battery is a deep cycled sealed maintenance-free battery designed for inverters, telecommunication and other applications involving battery back-up need that involve continuous charging and discharging. To keep your inverter as well as business up and running‎,‎ you need the Mercury 200 AMP Battery to convert the direct current to alternating current which set the output voltage in 200 amp‎‎ that meets the specification of your household appliances‎‎‎.‎‎ Power is stored in this battery as it is designed to store rechargeable current and provides a flow of power to your inverter when there is no public power supply available‎‎‎.‎‎‎ This Mercury battery is 200AH 12V‎‎‎.‎‎‎ It is also a lead acid battery‎‎‎,‎‎‎ what this means is that it will use a reversible chemical reaction to store its energy‎‎‎.‎‎‎ It uses lead plates in a solution of sulphuric acid which generates electric energy‎‎‎.‎‎‎ This electric energy is then used to power the inverter‎‎ which offers you stable light to enjoy all through the day‎.‎‎‎ The Mercury battery is the best method to provide alternative power for a limited period‎‎ as it typically takes some hours to recharge‎‎‎.‎‎‎ Here are some of the reason why the battery is best for you‎‎‎;‎ it has a low maintenance cost and it is not expensive to buy‎‎ unlike running your home with a generator‎‎‎,‎‎‎ the inverter operation is so quiet‎‎ and‎ there will be  no form of noise pollution‎‎‎.‎‎‎ Another important thing is that this battery has exceptional charge retention and recovering ability and also environmental friendly‎.‎‎‎ It has the ability to withstand overcharge‎,‎ discharge efficiently and‎‎ is not affected by shocks and vibration‎‎‎.‎‎‎ The battery can last for many years of continuous use before needing replacement‎‎‎‎ which‎‎ makes it a good choice as a back‎-up power provider‎‎‎.‎ Features:
  • Leak-proof and sealed construction
  • Maintenance free
  • Compact design and heavy duty grids
  • Low self discharge
  • Wide operating temperature
  • High impact resistive plastic cast
  • 56.5kg weight
  • 225mm x 523mm x 240mm volume
