 The European Standard EN50172 (BS5266 Part 8) calls, as a minimum, for emergency luminaires to functionally tested every month with a full rated duration test every year and states that the battery packs should be replaced as soon as the luminaire fails to meet its declared emergency duration.
In practice these battery packs will provide a service life in excess of the 4 years declared by the battery manufacturer against IEC285, providing they have been operated correctly and that their maximum operating temperature of 50º C has not been exceeded. |

Nickel Cadmium Batteries
In today’s competitive environment it is often the hidden elements of a product where savings” are made.
In the case of self contained emergency lighting luminaires, it is often the Nickel Cadmium battery
which is judged to be an item where money can be saved, often
to the detriment of product performance, life, maintenance, and ultimately safety of lives.
We have a policy of using quality, high temperature Nickel Cadmium
batteries manufactured by world class companies using premium
materials and graded to the demanding standards of IEC285, and
when installed and operated in accordance with EN60598.2-22 meet
the requirements for a 4 year life.
