Lithium Iron Phosphate battery

Ronda was one of the first battery suppliers in China who launched the range of lithium iron phosphate batteries for emergency lamps in 2012. After more than four years’ practical use it proved the good performance of lithium iron phosphate batteries in emergency lamps and exit lights.

Advantages of lithium Iron phosphate batteries:

  • excellent charging performance at high temperatures
  • extremely low self-discharge
  • over 1000 times cycle life
  • no memory effect
  • fast to charge
  • No toxic and harmful substances.

Lithium ion Phosphate VS Nickel Cadmium on Environmental Impact

There are now more and more concerns around the toxic and harmful substances found in Ni-CD and SLA batteries. These toxic substances are harmful to humans and the environment if not disposed of and recycled properly. In view of environment and health, Lithium Iron Phosphate contains no toxic heavy metals and no carcinogens. This provides a significant reason to consider lithium-ion over Ni-CD batteries.
