Battery Maintenance Tips

Mercury Elite 220Ah Tall Tubular Battery

  • Battery top should always be kept clean and dry.  Always use moist cotton cloth only.  Never use woolen / Silk or Synthetic cloth as it can create a spark.
  • Apply Protection Jelly (Vaseline) externally over the terminals and cable clamps to avoid corrosions.  Never apply grease. Terminal corrosion, dirt, and moisture causes loss of power and makes the battery weak.
  • The electrolyte level should be maintained as per the level indicator on the battery during installation or while topping up.  Do not top up with acid/electrolyte/ mineral water or tap water.
  • Water loss will happen during usage.  Check your battery regularly and maintain the electrolyte level within the band as per marks indicated.
  • Match charger to the battery


For 12v battery

  1. Charging current (A) 10% of C20 capacity with maximum champ voltage of 14.5V
  2. Trickle charge vol – 13.8V
  3. Battery discharge cut out voltage minimum 10.8V.

Solar energy prices hit record low India cancels plans for huge coal power stations

For the first time solar cost less than coal in India and the implications this has for transforming global energy markets is huge.

Measures taken by the Indian Government to improve energy efficiency coupled with ambitious renewable energy targets and the rate at which the cost of solar is falling has had a a marked effect on existing as well as proposed coal fired power plants, rendering an increasing number them financially undesirable.

The number of the global financial institutions who are bidding into India’s solar power infrastructure tenders is a strong approval of India’s leadership in this energy transformation and will have significant ripple effects into other transforming markets, as is already seen in the UAE, South Africa, Australia, Chile and Mexico.

How to use the Mercury Battery Backup Calculator

The Mercury Battery Backup Calculator is designed to help you determine how  long your inverter battery or bank of batteries will last on a full charge.    


Step 1: Battery Amp/Hrs

In the first field use the slider to select the total Amp/Hrs of your battery or bank of batteries.  For example If you are using a 12v inverter with two 200ah 12v Deep Cycle batteries,move the slider to 400.  Two 12v batteries connected in parallel equals 12 volts and 400 Amp/Hrs.

If you are using a 24v inverter with two 200ah 12v Deep Cycle batteries,move the slider to 200.   Two 12v batteries connected in series equals 24 volts  and 200 Amp/Hrs.  If you are using a 48v inverter with four  200ah 12v Deep Cycle batteries, move the slider to 200.  Four 12v batteries connected in series equals 48 volts and 200 Amp/Hrs.


Step 2: Inverter Voltage

In the second field select the voltage of your inverter.  For example if you are using a Mercury 1.2kva (Classic Model) select 12v.  If you are using a Mercury 2.4kva (Classic Model) or a 3kva (Mercury Soho) inverter select 24v and if you are using a Mercury 5kva (Mercury Soho) inverter select 48v.


Step 3: Load


In the third field enter the total wattage of appliances connected to the inverter.  You can find the wattage of each item by looking at markings on the body, in the user manual or with the help of a watt meter.


Step 4: Backup Hours

In the fourth field the Mercury Battery Backup Calculator will tell you how many hours you can expect your inverter to run till the battery or bank of batteries reach an 80% depth of discharge.

Amazing Nigerians Burn Away 5 Billion On Generators Annually

Amazing Nigerians burn away 5 billion on generators annually. According to the Speaker of the House of Representatives, Mr Yakubu Dogara lawmakers are reviewing some of Nigeria’s energy laws to offer a proper legal framework that would help renewable energy to the benefit of the economy.

Renewable energy is a source of clean energy which is environment-friendly and is crucial to the economy of the future. We can only be self-sufficient in the energy field when we combine all our energy resources such as the wind, solar, hydro, biomass, biofuel, landfill, sewage gas, solid waste, geothermal energy, ocean energy among others. The proper legal framework to exploit renewable energy which is nature’s gift to humanity is non-existent in Nigeria.

Nigeria is a country with enormous resources and untapped opportunities.   To meet its full potential experts in the power sector estimate that Nigeria will require an investment of at least 3.5 billion dollars annually in power generating capacity, with large investments required in the other supply chain of transmission and distribution networks.

Mr Babatunde Fashola, Minister for Power, Works and Housing, said in a lecture that the Federal Government’s road map for solving the country’s power crisis was to utilise incremental power wherever it could be found to achieve steady power supply.

In a bid to improve power generation, supply and distribution, the Federal Government signed a Solar Power Purchase Agreements worth 1.75 billion dollars with 14 companies to build 1,125 megawatts capacity of renewable power across the country. The Minister for Power, Works and Housing elucidated that the incremental power project of the Federal Government is the development of hydro power through the construction and rehabilitation of several hydro power dams in the country.

In addition, some of the ongoing power projects include the 30-megawatt Gurara hydro power plant in Kaduna, 10-megawatt Tiga dam hydropower plant in Kano, 10-megawatt Oyan dam hydro power plant in Osun and 8-megawatt Challawa dam hydropower plant in Kano.

There are reports that NEPA power supply has been stable in many areas of Lagos for the last few months. We have however been here before, such as in the early days of the Muhammadu Buhari government. The power supply from NEPA was constant, the price of generators and inverters were falling. The masses were hopeful that the hell they had lived in was coming to an end. What transpired in Nigeria since then has been hell times two. The country saw some of the worst power failures in living memory. The prices of generators and inverters have more than doubled. For example in 2015 you could buy a quality grid tied inverter with a built-in charger for N20,000. The same inverter now cost over  N50,000.

There are however signs that the situation is starting to change for the better with the recent announcement by the Transmission Company of Nigeria (TCN) that Power Generation Companies (GenCos) have deployed Free Control mechanisms in their power plants. The free governor is an important controller in the power plant as it regulates the turbine speed and power movement in the grid frequency regulation. According to power sector analyst, the deployment is responsible for the recent improvements in national grid power supply. Are you experiencing good NEPA supply area?

Flooding Causes Power Outages In Ikoyi Victoria Island

Flooding Causes Power Outages In Ikoyi Victoria Island. Eko Electricity Distribution Company on Sunday 9th July 2017 announced power outages in Ikoyi, Victoria Island and surrounding areas because some of their injection substations and equipment have been submerged in flooding.

The General Manager, Corporate Communications, EKEDC, Mr Godwin Idemudia, said they were having challenges in almost all its injection substations, as a result of the flood from Saturday’s heavy rains.

He said that the management had directed that transmission is ‘deloaded’ in the affected areas for safety.

The injection substations affected by the flood include Lekki Transmission Station, Agungi, Lekki, Ademola and Anifowoshe.

Victoria Garden City, Water Front, Maroko and Oniru Injection Stations are completely out.

“”We need to look at the extent of the effect of the flood on our equipment.

“However, we are presently working round the clock to restore supply to our esteemed customers,” he said.

It at times like these that an inverter backup system becomes so precious that its value cannot be determined.  When you run your generator you won’t be just burning away fuel, you will be charging your batteries.

The Mercury 2.4kva-Complete Inverter System which comes with two  Mercury Elite 200ah Deep Cycle Batteries included can provide backup power for up to 12 hours depending on usage.  If your TV is on continuously along with lights and fans it can run for up to 6 hours.   If you add four 300 watts solar panels to this setup, you can have 24 hours power with or without NEPA.”

Mercury Inverter Tips and Tricks

Get to know your Mercury Inverter. Learn the Mercury inverter tips and tricks to get the most out of your Inverter.

1. Use new Deep Cycle Batteries

The main job of an Inverter is to convert DC to AC, it draws from one or more batteries to power your home or office appliances. The best batteries for Inverter usage are Deep Cycle batteries. They are designed to provide a steady amount of current over a long period of time and to be deeply discharged over and over again.

2. Choose the right size Inverter for your needs

When it comes to Inverters, bigger does not always mean better. Choosing the wrong size Inverter could mean that you spend significantly more money than you need too. In most cases the bigger the capacity of Inverter the higher the voltage required to power it.

A 1.2kva Mercury Inverter requires only one 12 volts. A 2.4kva Mercury Inverter requires two 12 volt batteries connected in series to generate the required 24 volts.

3. Use Energy Saving Bulbs

Compared to normal light bulbs energy saving bulbs use on average about 25% – 80% less energy. Which means less load on your Inverter and longer runtime.

4. Use Energy Efficient Home Appliance

They will not only help you save money. They will also help you increase the number of hours your Inverter can run for each day. Both LG and Samsung have state of the art energy-efficient products. For example, you can buy A+++ Air conditioners, fridges and TVs and there are now TVs available which use less energy than a light bulbs

5. Implement Energy Saving Practices

Switch things off when you are not in the room, for example, lights, TVs, fans and game consoles.   Make “”turn it off when done”” a family habit.

6. Respect Low Battery Alarm

When the Low Battery alarm on the Mercury Inverter sounds, turn the Inverter off. The alarm is there to warn you that the level of discharge is low. If you don,t turn off the alarm, your batteries will be excessively drained. If you continue to do this day after day you will eventually ruin your batteries.

7. Fully Charge New Batteries

When you buy new Mercury inverter batteries, make sure to  charge them for 8 hours, before using for the first time. This will help ensure they service you longer.

8. Use Identical Batteries

For best performance, ensure all batteries are of the same brand, age and capacity.

9. Read the Manual

Before you install and use a Mercury Inverter. Read the user manual, all instructions and cautionary markings on the device and on the batteries.

10. Use Automatic Changeover Mode

Your family will not have to run around when NEPA strikes, the lights will remain on and the DSTV will not restart in the middle of your favourite programme.”
