Product Description
CUSTOM-415 Replacement Battery for Day-Brite McPhilben Emergency Lighting
The CUSTOM-415 is a 6V 800mAh Nickel Cadmium (NiCd) rechargeable battery pack designed as a direct replacement for the Day-Brite McPhilben 45VX6VB emergency lighting battery. It replaces OEM part numbers 45VX6VB and OSA294, and installs directly into compatible Day-Brite and McPhilben emergency exit and emergency lighting fixtures via the original connector — no soldering required.
Emergency Lighting Application
Emergency lighting batteries are life-safety components required by building codes to power exit signs and emergency lights during power outages. The most common reason for emergency lighting failure during an annual test is a degraded or dead battery. Replacing the battery on a regular cycle — typically every 3–5 years, or when the fixture fails its test — restores the fixture to full compliance without replacing the entire unit.
The CUSTOM-415 is designed for Day-Brite and McPhilben brand emergency fixtures that use the 45VX6VB battery. Day-Brite and McPhilben are the same brand family, now part of Signify (formerly Philips Lighting). If your fixture label references either Day-Brite or McPhilben with a 6V battery pack, the CUSTOM-415 is the correct replacement.
Installation
The CUSTOM-415 uses a pre-wired connector termination that mates directly with the fixture's internal wiring harness. Disconnect the old battery pack, connect the new one, and secure it in the battery compartment. No soldering or special tools are required. Always follow your fixture's service documentation and applicable electrical safety procedures when replacing emergency lighting batteries.
NiCd Battery Maintenance and Disposal
Nickel cadmium batteries perform best when kept on float charge in the fixture between tests. Avoid storing discharged NiCd packs for extended periods as this can cause cell reversal and reduce capacity. NiCd batteries contain cadmium and must be disposed of in accordance with applicable local, state, and federal regulations — do not dispose of in regular trash. Many municipalities offer household hazardous waste collection for NiCd batteries.
Frequently Asked Questions
What emergency lighting fixtures use the 45VX6VB battery?
The 45VX6VB is a battery pack used in Day-Brite and McPhilben brand emergency lighting fixtures. Day-Brite and McPhilben are the same brand family. If your fixture has a label referencing either brand and shows a 6V battery, the CUSTOM-415 is the correct replacement. Confirm the OEM part number on your existing battery before ordering.
What is the difference between Day-Brite and McPhilben?
Day-Brite and McPhilben are the same brand family. McPhilben was acquired by Day-Brite CFI, which is now part of Signify (formerly Philips Lighting). Fixtures may be labeled as either Day-Brite or McPhilben depending on when they were manufactured, but they use the same battery platform.
How often should emergency lighting batteries be replaced?
Most emergency lighting battery manufacturers and building codes recommend replacing NiCd emergency lighting batteries every 3 to 5 years, or immediately when a fixture fails its annual 90-minute discharge test. Regular replacement is the most reliable way to maintain code compliance.
My emergency light failed its annual test. Is the battery the likely cause?
In most cases, yes. A degraded battery is the most common cause of emergency lighting test failure. If the fixture's lamp is functioning but it won't sustain illumination during the discharge test, replacing the battery is the recommended first step before replacing the entire fixture.
Is NiCd the correct chemistry for my Day-Brite fixture?
Yes — the original Day-Brite McPhilben 45VX6VB is a NiCd battery, and the CUSTOM-415 uses the same NiCd chemistry. Do not substitute a different chemistry without confirming compatibility with the fixture's charging circuit, as emergency lighting fixtures are designed to charge a specific battery chemistry.
How do I dispose of the old NiCd battery?
NiCd batteries contain cadmium, a regulated hazardous material. They must not be disposed of in regular trash. Check with your local municipality for household hazardous waste collection options, or use the Call2Recycle program, which provides free NiCd battery recycling drop-off locations nationwide.
What is the warranty?
The CUSTOM-415 carries a 12-month warranty.
