When should a battery pack for an emergency lighting fixture be replaced? 

According to the NEN 1010 and NEN 1838 safety standards, emergency exits and escape routes must be illuminated by a minimum of 1 Lux at all times. In the event of a power failure, emergency lighting must be able to provide this level of illumination for a minimum of one hour. Over time, however, batteries lose their capacity. The manufacturer of our battery packs indicates a maximum operational lifespan of 4 years. Though the battery is still likely to function after this 4 year period, they will never deliver the required light output. Therefore, you are legally obligated to replace the battery pack once every four years. When you meet this requirement, your battery packs will always supply the necessary hour of electricity to your emergency lighting fixtures.

Battery pack autonomy

When a battery pack is tested, one essentially tests the autonomy of the battery pack. Battery pack autonomy is an indication of the amount of time it takes for the battery pack to be completely discharged. In these situations, we check whether your emergency lighting fixture supplies light for at least one hour after disconnecting it from mains power. If a tested battery pack no longer achieves the required duration of autonomous output, Intercel can supply a battery pack from stock for each emergency lighting fixture on the market. An added advantage of Cellpower battery packs is that they are made with HT (High Temperature) power cells which are capable of resisting ambient temperatures of up to 65°C. Intercel delivers the right battery for emergency ligthing.
