There are numerous places where you can pick up a batter emergency light. First, try http://www.emergencylightbatteries.com/ or your local home improvement store.
An emergency light is connected by attaching one set of wires to the buildings wiring and another to a built in battery. When the light detects the power has been cut, it will automatically switch over to its battery and turn on.
Consulting your user guide is a good starting place for determining if you need to change your battery emergency light in your home security system. If the battery is not the cause there may be other trouble shooting tips located in the manual.
Emergency lights usually contain batteries which are kept in a state of charge while the power is on. When power is removed the fitting will detect this and switch on using the internal battery. Emergency light will only run for the life of the battery normally about 3 hours.
The two most common battery types used for emergency lighting are lead acid and nickel cadmium.
The battery warning light illuminates when the battery isn't being charged , get it checked out to find the problem and then repair.
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

You can find a battery powered generator at your local home depot store, some do carry it. If not, try Amazon.com or Bowens USA. They carry a lot of brand name battery powered generators.
Having too much play in the emergency brake handle in the middle of the console could lead to the brake light flickering. At least this was true for me.
Is it possible that somebody else turned the emergency flashers on without your knowledge? And if so , over time the battery will get drained of it's power as if you were listening to the radio for a while. Just a thought .
I think these beeping sounds usually mean the internal battery has a fault and will need looking at
An emergency light switch uses a relay. A relay has an 5 terminals. The firs two terminals are connected to a flowing current (current flows when there is a normal electricity) The next 3 terminals are the common, the normally on, and normally off. One of the battery terminal is connected to the common, and the other one terminal of the battery is connected to one terminal of the light bulb(which has two terminals) then the other terminal of the light bulb is connected to the normally on terminal of the relay. When current flows to the first two mentioned terminals of the relay, the circuit of the battery and light is cut off or not connected. But when the current is off, this will switch on the normally-on terminal thus current will flow from the battery to the light bulb, that will shed light. ;) on an emergency situation. note: The normally off is not use. And may be use for some purpose.
