Description

Tran-Bal 40000009 Battery Replacement – 3.6V Ni-Cd Emergency Lighting Pack

If your emergency light or exit sign fails a monthly test, won’t stay illuminated during an outage, or has reduced runtime, a worn battery pack is often the cause. This Tran-Bal 40000009 3.6V Ni-Cd battery replacement is designed to restore dependable backup power in compatible emergency lighting fixtures that require a 3.6 volt nickel-cadmium battery pack.

Confirm Correct Fit Before Ordering Emergency Light Replacement Pack (Very Important)

• Voltage must match: 3.6V exactly (typically 3 cells × 1.2V each).
• Connector: 2 Pin
• Chemistry should match: Replace Ni-Cd with Ni-Cd unless your fixture label allows alternatives.
• Connector must match: Compare plug shape, pin count, and polarity to your original.
• Pack size matters: Confirm length/width/height will fit your battery compartment.
• High Quality Long Life D NiCd Cells

Why Replace the Battery Pack?

Emergency lighting batteries naturally lose capacity over time due to age, heat, and repeated charge/discharge cycles. Replacing the battery pack helps ensure your fixture performs properly during power loss and routine inspections.

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

• Read the battery 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 one is D cells.
• Check the connector: Even if voltage matches, the wrong plug will not connect safely.
• Measure the pack: Small differences in length or width can prevent the battery door from closing.
• Fixture model helps: If you provide the fixture model number and battery photos, matching is faster and more accurate.
