Step 1-Pick up the screwdriver and open the casing. Although some hazardous locations where vandalism-proof lighting equipment will be used will use a dedicated hex screwdriver, we hope that you or your maintenance department will retain the attached accessories when purchasing the equipment.

Step 2-Now that you have removed the printing plate, you will see many wires (don't worry about its normal). Some of these red, black, blue or white wires will lead from the alternating current conduit to the voltage transformer, which leads to the switching circuit. One, two or several wires connect the circuit board to the battery.

Step 3: Depending on the emergency light, the battery will be a sealed lead acid (SLA) or nickel cadmium (NiCd) battery type. SLA looks like a stroller battery, while NiCd is usually similar to ordinary household AAA batteries and is sealed with a protective plastic shrink film.

After unplugging the wires from the + and contacts, most batteries will slide out of the device. Some batteries will be placed in the wiring harness, and you must also remove them.

Determine the correct battery replacement
Remove the harness and battery from the case. The first thing to note is the voltage, usually 6v or 12v. Do not try to use 12V batteries in 6V emergency lights, and vice versa.

One of the fastest ways to find the battery type is to simply look at the label inside the case. Displayed on this wetland emergency light: "Replace with container type: JM-6M10.0AC"

Please make sure to determine the battery voltage (6V or 12V), size (length x width x height (inch)) and terminal type to provide a new battery. But you said, wait, what is the terminal type?

Identify the battery terminal type
Sealed Lead Acid (SLA)
Faston lugs (as shown) are the most commonly used terminals for this battery. Your illuminator will provide a red, black, and white blade connector that slides on these lugs to close the circuit.

Some larger batteries have L terminals. They have an L-shaped pillar with a bolt hole in the vertical direction. These are very similar to car battery terminals, so unless they are heavy-duty models designed to extend emergency operating time, they will be extremely rare.

Nickel Cadmium (NICD)
The mother-to-mother battery lead is a bullet connector that is easy to insert, making wiring of multiple NiCd batteries fast and simple. Since each battery in the battery pack has its own positive and negative terminals, multiple batteries are combined into one easy-to-connect wire.
