Emergency Lighting Batteries
Replacement and OEM battery solutions for emergency and exit lighting systems. Compliant with AS/NZS 2293, stocked across standard configurations, and available to electrical contractors, facility managers and manufacturers.
Emergency lighting systems in Australia must comply with AS/NZS 2293.1 for design and installation, and AS/NZS 2293.2 for inspection and testing. The battery is the most failure-prone component in any emergency luminaire — and non-compliant or degraded cells are a common cause of failed inspections.
We supply batteries that meet the electrical and performance requirements for use in compliant emergency lighting systems, across the voltage and capacity combinations most commonly found in the Australian market.
Whether you're doing a routine battery replacement, retrofitting an aging system, or sourcing cells for new luminaire production, we can supply the right battery to spec.
Nickel Cadmium (NiCd)
The industry standard for emergency lighting for decades. NiCd cells are robust, tolerant of deep discharge, and perform reliably across a wide temperature range — qualities that matter in emergency applications where batteries may sit on standby for extended periods before being called into service.
Suited for: Direct replacements in existing NiCd-based emergency luminaires, particularly in older buildings or where existing battery housings must be retained.
Key characteristics:
- Long cycle life — typically 500+ charge/discharge cycles
- Strong performance in high and low ambient temperatures
- Tolerant of sustained trickle charging, as used in most emergency lighting circuits
- Available in standard stick and pack configurations
Nickel Metal Hydride (NiMH)
NiMH offers higher energy density than NiCd in the same form factor, making it a viable drop-in upgrade where space is constrained or longer backup duration is required without changing the luminaire housing.
**Suited for:** Retrofit upgrades in NiCd luminaires where extended backup duration is desired, and new luminaire designs specifying a higher-capacity pack.
Key characteristics:
- Higher capacity than NiCd in equivalent physical size
- Lower self-discharge variants available for long standby applications
- No cadmium — easier to manage under waste and environmental compliance obligations
- Compatible with standard emergency lighting charge circuits (constant voltage/trickle)
Lithium Iron Phosphate (LiFePO4)
LiFePO4 is increasingly specified in new luminaire designs for its superior energy density, extended service life, and stable chemistry. Unlike other lithium chemistries, LiFePO4 is thermally stable and safe for use in enclosed luminaire housings.
Suited for: New luminaire designs and purpose-built emergency lighting assemblies where longevity and reduced maintenance intervals are priorities.
Key characteristics:
- Cycle life typically exceeds 2,000 cycles — significantly outlasting NiCd and NiMH
- Flat discharge curve ensures stable voltage delivery throughout backup duration
- Operates safely across a wide temperature range with no thermal runaway risk
- Requires compatible charge management circuit — confirm compatibility before substituting into NiCd/NiMH designs

Who We Supply
Electrical contractors
We supply individual replacement batteries and bulk packs for maintenance rounds. If you service multiple sites, we can set up a trade account with volume pricing and fast dispatch.
Facility managers and building owners
Keeping your emergency lighting compliant under AS/NZS 2293.2 means scheduled battery replacement — typically every 3–4 years depending on battery chemistry and system usage. We can help you identify the correct replacement specifications for your installed luminaires and supply accordingly.
Luminaire manufacturers and OEMs
We supply battery cells and assembled packs for integration into new emergency lighting products. Custom pack configurations, connector specifications, and bulk order arrangements are available.
