Batteries for Emergency Lighting Units (ELUs) are essential components in fire safety and evacuation systems. ELUs are devices that provide emergency lighting in the event of a power failure, guiding the occupants of a building to emergency exits safely and efficiently. Batteries play a crucial role in this operation, ensuring a backup power supply.

How Batteries Work for BAES

Batteries for BAES are specially designed to provide a reliable and continuous source of energy during a power outage. They are typically made of technologies such as nickel-cadmium (Ni-Cd), nickel-metal hydride (Ni-MH) or lithium-ion (Li-ion), each type having its own advantages in terms of cycle life, charge capacity and maintenance.

Types of Batteries Used

Nickel-Cadmium (Ni-Cd) : These batteries are robust and offer a long service life, even in extreme temperature conditions. They are often used in BAES because of their reliability and ability to operate efficiently after long periods of non-use.
Nickel-Metal Hydride (Ni-MH) : Ni-MH batteries are more environmentally friendly compared to Ni-Cd, as they do not contain toxic cadmium. They also offer good charge capacity and are less prone to the memory effect, meaning they can be recharged to partial levels without significant loss of capacity.
Lithium-Ion (Li-ion) : Known for their high energy density and low weight, Li-ion batteries are increasingly used in BAES. They have a longer life and superior charge and discharge performance. However, they are also more expensive and require sophisticated protection circuits to ensure safe use.

Importance of Maintenance

To ensure the reliability of BAES, it is crucial to keep the batteries in good condition. This includes regular testing, visual inspection for signs of corrosion or leakage, and replacing the batteries at the end of their life cycle. A faulty battery can compromise the effectiveness of the emergency lighting, putting the safety of building occupants at risk in the event of an emergency.

Standards and Regulations

Batteries for BAES must meet strict standards to ensure their efficiency and safety. These standards cover aspects such as battery performance, durability and safety, ensuring that they meet the requirements necessary for reliable use in emergency situations.

Conclusion

Batteries for BAES are a vital part of emergency lighting systems, providing a vital backup power source in the event of a power outage. Choosing the right battery type, performing regular maintenance and ensuring safety standards are key to ensuring BAES operate efficiently when they are needed most. By investing in and maintaining high-quality batteries, building managers can effectively protect occupants and comply with current regulations.
