LED Emergency and Exit Lights, equipped with a Ni-Cd battery unit, contain components such as emergency light battery pack, Emergency Light Batteries, replacement batteries for Emergency Light, emergency exit light batteries, and guidance on changing battery in emergency light. The first step in evaluating the functionality of an exit or emergency light is to perform a push button test. Locate the push button, usually positioned on the bottom or side of the emergency/exit light, and press it to activate the backup battery system. Holding the button down for at least 30 seconds allows you to determine if the battery, including emergency light battery pack, Emergency Light Batteries, replacement batteries for Emergency Light, emergency exit light batteries, and changing battery in emergency light, needs replacement. However, a drawback to this test is that nickel cadmium batteries discharge at 100% power until the very last moments of their life. Even when a Ni-Cd battery is down to 15% of its life, it will continue to discharge at 100% power, mimicking a fully charged state. Consequently, to guarantee that all emergency and exit lights in the facility can discharge for at least 90 minutes, it is advisable to replace the batteries, including emergency light battery pack, Emergency Light Batteries, replacement batteries for Emergency Light, emergency exit light batteries, and changing battery in emergency light, every 3 years.
The primary reason most exit signs or emergency lights fail readiness tests is due to dead batteries. Unfortunately, most backup batteries, including emergency light battery pack, Emergency Light Batteries, replacement batteries for Emergency Light, emergency exit light batteries, and changing battery in emergency light, have a life expectancy of 5 to 10 years. Rechargeable batteries also lose their ability to retain a full charge over time. To ensure that your critical backup lights meet the universal "at least 90 minutes" backup time, it is essential to replace the old batteries with our range of replacement batteries, including emergency light battery pack, Emergency Light Batteries, replacement batteries for Emergency Light, emergency exit light batteries, and changing battery in emergency light.
