Emergency Lighting & Exit Sign Battery Guide

Emergency lighting and internally illuminated exit signs use rechargeable backup batteries so the fixture can continue operating when normal building power is interrupted. The correct replacement depends on the fixture design, original battery specification and charging system.

How do I find the correct emergency-light battery?

Start with the original battery part number or fixture model whenever possible. If that information is unavailable, compare the battery chemistry, voltage, capacity, terminal or connector type, dimensions and wire configuration. Matching voltage alone is not enough.

What battery chemistries are used in emergency lighting?

Common emergency-lighting applications use rechargeable batteries such as nickel-cadmium (NiCd) and sealed lead-acid (SLA/AGM), with other chemistries used in some fixture designs. Always match the chemistry required by the original fixture and charging circuit.

Do emergency lights and exit signs use the same batteries?

Not necessarily. Exit signs, emergency lights and combination fixtures can use different voltages, capacities, chemistries, connectors and battery-pack configurations. Match the replacement to the specific fixture or original battery number.

Can I replace an emergency-light battery with one that has the same voltage?

Not based on voltage alone. The replacement also needs to meet the fixture's requirements for chemistry, capacity, terminal configuration, physical size and charging characteristics.

How long should emergency lighting operate during a power outage?

Many listed emergency-lighting fixtures are designed for at least 90 minutes of emergency operation, but required performance depends on the fixture, installation and applicable safety requirements. Follow the fixture manufacturer's documentation and local requirements when testing or servicing emergency lighting.

Why do emergency-light batteries need replacement?

Rechargeable batteries gradually lose capacity with age and use. Heat, charging conditions, discharge cycles and extended service time can all reduce available runtime. Replace a battery when it no longer meets the fixture manufacturer's required testing or performance criteria.

What information should I have before ordering?

The most useful information is the fixture manufacturer, fixture model, original battery number, voltage, capacity, chemistry, dimensions and terminal or connector type. That information provides the best path to identifying the correct replacement.
