Confirm Correct Fit Before Ordering (Very Important)

Even if the part number looks close, small details can prevent a safe connection. So please confirm the points below before purchase.

• Voltage must match: 3.6V exactly (typically 3 cells × 1.2V).
• Chemistry should match: replace Ni-Cd with Ni-Cd unless your fixture label approves alternatives.
• Connector must match: compare plug shape, pin count, and polarity to your original.
• Pack size must fit: confirm the listed dimensions will fit your battery compartment.

Why Replace the Battery Pack?

Emergency lighting batteries lose capacity over time due to age, heat, and repeated charge/discharge cycles. As a result, runtime drops and tests may fail. However,
replacing the pack helps your unit perform correctly during power loss and during routine inspections.

Battery Pack Highlights

• Built with new Ni-Cd cells for reliable standby runtime
• Designed for emergency lights and exit signs that specify a 3.6V Ni-Cd pack
• Supports routine push-to-test, monthly, and annual emergency lighting checks

Compatible Fixtures / Applications

This battery is commonly used in select emergency lighting units and exit sign fixtures that specify a
3.6V Ni-Cd battery pack. Because fixture families vary by connector and space, please match your original battery label, plug, and dimensions. If anything
looks different, reach out before ordering.

Information Gain: How to Identify the Right 3.6V Emergency Lighting Battery

• Read the label: confirm it states 3.6V and Ni-Cd.
• Count the cells: 3.6V packs are usually 3 rechargeable cells wired in series (3 × 1.2V). This pack uses D cells.
• Check the connector: even if voltage matches, the wrong plug won’t connect correctly.
• Measure the pack: small differences can stop the door from closing or pinch wires.
• Use the fixture model: with the model number and photos, matching is faster and more accurate.
