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.
