FL range

The nickel-iron battery of the FL range is having nickel oxide-hydroxide positive plates and iron negative plates.

The active materials are held in nickel-plated steel tubes or perforated pockets. 

The technology has regained popularity for off-the-grid applications as a constant voltage supply for backup power supply.

Nickel–iron batteries do not have the lead, cadmium, and cobalt which require treatment as hazardous materials. That is why they found a wide recall in the EU.

The storage batteries of FL range are used in cases where long-term discharges with relatively low currents are needed (0,2 C).

Depending on the type of battery and customer’s requirement, the complete set may include

  • Bars to connect cells
  • Cables with fittings to connect battery banks (length as may be required), nuts and washers to fix bars and cables
  • Spare valves
  • Wrench to assemble the battery

The storage batteries can be supplied in containers.
