Emergency battery cabinet battery replacement

In the case of battery replacement in an emergency light, it is important to insure that the same battery voltage, as well as the same battery type is installed. Too high a voltage will blow the lamps, while too low a voltage will cause the lamps to be dim.

Typically, lead-acid batteries are used in steel enclosure emergency lights and nickel-cadmium batteries are used in thermoplastic housing emergency lights. It is important to note that in the case of battery replacement, the same type of battery must be used as the unit originally contained.

Batteries used in emergency lights also come in a variety of voltages, from 6 VDC to 24 VDC. Higher voltages allow for brighter lamps to be connected to the emergency lights. They also work better where a remote lamp-head needs to be attached to an emergency light unit, as there will be less voltage loss over the line distance.

All emergency lights and lighted emergency exit signs use a battery for powering the lamps. In order to insure continuous readiness and operation of the emergency light, these batteries are rechargeable. Circuitry within the emergency light both charges the battery and insures that it stays charged.

Per OSHA guidelines emergency light owners should perform regular scheduled maintenance at monthly and annual intervals. If either the 90-second or 90-minute emergency readiness tests prove unsatisfactory (i.e. the lamps don't light up) replacing your emergency light batteries may be required.

OSHA (Occupational Safety and Health Administration) guidelines require scheduled preventative maintenance to insure the units will work during a power outage. Battery test buttons come standard on all emergency lights.
