AimLite replacement battery for LUMB and LUMBA emergency "Exit" signs, for 90 minutes of lighting.

AimLite replacement battery for LUMB and LUMBA Exit signs

The AimLite replacement battery (LBLUM) is the original accumulator designed for the illuminated "Exit" signs of the LUMB and LUMBA models. When a power outage occurs, this battery takes over and keeps the sign lit for 90 minutes, the regulatory time required to allow a calm and safe evacuation of the occupants. Over time, every emergency lighting battery loses its charge capacity: replacing it periodically ensures the sign stays fully functional on the day it is actually needed.

This replacement battery is the reliable option for maintaining an existing fleet of Exit signs without having to replace the entire sign. By keeping the original AimLite part, you ensure exact electrical compatibility (voltage and capacity) and proper operation of the charging circuit built into the sign. It is simple, cost-effective preventive maintenance that extends the service life of your fire safety equipment.

Benefits of the replacement battery for Exit signs

Beyond a simple swap, choosing the original battery brings concrete benefits for compliance and the building manager's peace of mind.

90 minutes of runtime compliant with evacuation

The battery delivers the emergency lighting duration expected from an Exit sign: 90 minutes of continuous illumination after a power cut, enough to guide occupants toward the exits even during an extended outage.

Direct compatibility with LUMB and LUMBA signs

Designed specifically for AimLite LUMB and LUMBA models, this battery installs as a direct replacement for the original accumulator, with no modification or adaptation, reducing maintenance time and the risk of error.

Worksites and sectors where this replacement battery is required

Periodic replacement of Exit sign batteries is required everywhere evacuation signage must stay functional:

• Commercial buildings, offices and apartment buildings equipped with battery-backed Exit signs.
• Institutional facilities (schools, hospitals, long-term care homes) where emergency lighting is strictly regulated.
• Retail stores, restaurants and hotels that must keep their exits clearly marked.
• Industrial buildings and warehouses subject to emergency lighting system inspection.
• Any maintenance manager replacing an end-of-life battery during a monthly or annual test.

Installation and maintenance of the Exit sign battery

Replacement is done by disconnecting the old battery from the sign and connecting the new one to the same connector: no soldering or specialized tool is required. After installation, it is recommended to let the battery charge fully, then perform a discharge test (the sign's test button) to confirm the runtime. A short monthly test and a full annual test help detect an end-of-life battery in time and stay compliant with emergency lighting requirements.

FAQ about the LBLUM replacement battery for Exit signs

Does this battery fit all Exit signs?

The LBLUM battery is designed for AimLite Exit signs of the LUMB and LUMBA models. For another sign model or manufacturer, check the original voltage and capacity before ordering.

How often should the battery be replaced?

The service life of an emergency lighting battery generally ranges from 3 to 5 years depending on use and temperature. If a discharge test no longer holds 90 minutes, it is time to replace it.

How long does the sign stay lit on battery?

Once fully charged, the battery provides 90 minutes of Exit sign illumination during a power outage.
