Frequently Asked Questions
Why buy a Nickel Iron Battery?
* They have the longest life of any rechargeable battery made today
* They have withstood the test of time (some of Edison’s original batteries are still working today 80 years+)
* Environmentally friendly green technology battery (no lead, mercury, cadmium or other toxic heavy metals)
* Efficiency of the battery is constantly around 80% over its entire life (based on system set up)
* Costs less per amp hour than any other battery (based on the life of the battery)
* Does not SULFATE
* Does not FREEZE
* If the battery stops holding its charge you can easily rejuvenate it by a simple electrolyte change
* The electrolyte is alkaline (the alkaline electrolyte protects the internals of the battery, unlike acid batteries)
* No need to do frequent equalization charges
* Old technology that today’s technology cannot beat in life cycles
* You can replace one cell if it fails (most other batteries you need to replace the entire battery)
* The entire battery is recyclable
* Extremely strong and durable
How long can I expect my nickel iron batteries to last?
No one knows how long a nickel iron battery will last for as some of the original batteries manufactured by Thomas Edison’s battery storage company are still in use today.
The new wave of nickel iron batteries have been manufactured for over 30 years and are still in use today, still producing one hundred percent of their rated capacity. Ironcore batteries believe NiFe batteries have the possibility of many years in excess of the 40 years.
What is the electrolyte made up of?
The electrolyte is Potassium Hydroxide mixed with distilled or de-ionized water. Water makes up around 70% of the electrolyte. Electrolyte replacement is inexpensive when compared to battery replacement. Nickel iron batteries like to be worked and thrive on hard work and cycling. If the battery is not producing its rated capacity its time for an electrolyte replacement.
What is a Nickel Iron battery cell?
A nickel Iron cell is made up of several pockets, each made of finely perforate strips and filled with active material and are mechanically manufactured to form a rectangular shape and then trimmed with steel frames to make a sheet – like plate. The plates are assembled and are separated and insulated from each other by means of plastic rod separators and/or edge insulators.
What is a Nickel Iron battery?
Nickel Iron batteries are made up from individual cells.
Each cell has a nominal voltage of 1.2 volts. No matter the size of the cell, all Nickel Iron cells are 1.2volts.
To make a battery, you add cells together until you get the voltage you require.
Example: 6 Volts = 5 x 1.2volt cells, 12 Volts = 10 x 1.2volt cells, 24 Volts = 20 x 1.2volt cells, 48 Volts = 40 x 1.2volt cells
The advantage of making a battery up from individual cells is that if one cell fails, you replace that cell. You can add to your battery bank at any time with Nickel Iron batteries if you need to store more power. This cannot be done with lead acid batteries without reducing the life of the new batteries.
What type of battery charger do I use?
You can either use a separate manual battery charger or an inverter with a built in battery charger. These batteries like to be charged between 1.6 and 1.75 volts per cell. (12Volt ~ 16 - 17.5volts, 24volt ~ 32 – 35volts etc)
I have a solar system, do I have to use a charge controller with Nickel Iron batteries?
No you do not have to use a charge controller on these batteries as these batteries can be overcharged without damage. The higher and frequent charges will require 2 - 4 electrolyte checks per year with electrolyte a maximum of 2 top ups per year. Consult with your expert on if your inverter is able to operate with higher voltages as you may need to control the voltage of the battery so you do not damage your inverter.
How efficient are these batteries?
The NiFe battery has an efficiency of around 80%. A new battery requires to be fully cycled a number of times to obtain it rated capacity. It can take up to 50 cycles for this to occur. A Nickel Iron battery over its life will be more efficient than most other batteries as most batteries efficiency reduces dramatically nearing the end of their life.
Can they be used with renewable energy systems (Solar or Wind)
YES! Most popular inverters can be used with NIFE batteries including maximum power point tracker (MPPT). Most common inverters are set for a lead acid battery working range of 10.5 volts to 13.5 volts in a 12volt system. A NIFE battery has a working range of 9 volts to 17 volts in 12 volt system meaning you have more usable stored power than most other batteries on the market.
Please contact us if you are not sure about your inverters ability to use the working range of a NIFE battery.
Maintenance of the batteries?
Maintaining the batteries is as simple as making sure the cell tops are clean from dust or dirt and kept dry. Washing them once a year assists this. Maintaining the water level in the battery is vitally important.
Can I store them without use over a long period of time?
Yes they can be stored for a long time without use or the need to be trickle charged. Ideally if you are not going to use the battery for as extended period, they prefer to be totally discharged and emptied of electrolyte. Then when you need to re use them just refill the electrolyte and charge them back up and they will perform as they did prior to the storing them.
