Why emergency lighting batteries are so important
Emergency lighting is an important source of light that comes on automatically when there is a power cut. It is a requirement in commercial and government buildings, e.g. hotels, prisons, hospitals, factories, etc, that they need to be lit even during a power failure. Street lights are another important application.
Obviously having to provide back-up batteries for emergency lighting and exit signs that are reliable and will last for long periods is of utmost importance, as they are the main factor when it comes to emergency lighting working properly as and when it is needed. It is necessary to provide back-up batteries for emergency lighting and exit signs in order to meet building compliance and health and safety regulations.
Types of emergency lighting batteries
Emergency lights and exit signs most often use LEDs as they use a minimum of electricity and have a long life span. This means that less maintenance is required and makes them more reliable. LED emergency lighting usually uses either sealed lead acid or nickel cadmium batteries.
Nickel cadmium batteries are more expensive than lead acid batteries, but are generally preferred for emergency lighting as they have a much longer life expectancy, are smaller and weigh less. They are also resistant to temperature extremes and don’t lose their charge in these situations like other batteries tend to.
