An emergency ballast is a lighting ballast that has an internal battery. This battery will store enough energy to power the light for a short amount of time. Typically this battery is not designed to last through long power outages. Rather, it is normally used in conjunction with a backup generator. In the event of a power loss, the ballast immediately carries the load of the light, until the generator comes online. Some manufacturer's do not combine the ballast and the battery in the same metal can; they use 2 separate cans. The battery part in many instances does not light all the lamps of the fixture and it may only light the lamps about half brightness. The purpose is only to assist in evacuating the building

How do you replace ac ballast where emergency ballast present?

First you need to determine if it's the ballast that's bad or the emergency ballast. The emergency ballast can go bad and cause the bulbs not to work or not all of them to work depending on the lights wiring setup. Push the test button on the emergency ballast which should have a red glowing indicator light. If all the lights illuminate slightly, change the emergency ballast. It's best to buy the exact ballast for this repair. i.e. If it's a T8 3 lamp fixture. Buy a T8 3 lamp ballast not a 4. You can use a 4 in place of a 3 lamp, but the 3 lamp will be more user friendly. Easiest way is to note what wires go to what. Draw a diagram if you have to and just simply match them back up.
