Clevertronics Emergency lighting and batteries

14 March 2019

FOR MANY years self-contained emergency lighting products have been using Nickel Cadmium and Nickel metal hydride batteries as these were well suited to the application mainly due to their size, weight and ability to provide the required power for the desired duration.

On the flip side these same batteries contain materials that are toxic to both human health and the environment. They contain the toxic heavy metals Nickel or Cadmium. Nickel and Cadmium are “known” carcinogens. 

As result The EU “battery Directive” restricts the use of these batteries. Emergency lighting is exempt, along with some other “critical use” or “essential security” applications.

There is an alternative! Lithium Iron Phosphate (LiFeP04 or LFP) batteries have been used in emergency lighting applications for many years and contain no toxic heavy metals and no carcinogens. A variant of LifEP04 batteries using a patented “Nanophosphate” for the cathode material achieves at least twice the calendar life of existing technologies and because it features a much higher energy density, is less than half the size and weight.

Is it time to make the switch, protect the environment and save money at the same time?
