The
Importance of Emergency Lighting
Batteries
Emergency lighting systems are vital light sources that illuminate
automatically during power outages. They are obligatory in commercial and
government buildings that require light at all times even during a power failure.
Buildings that do not have a back-up generator that keeps the exit
and emergency lighting systems functional during a power outage are required to
have exit signs with battery back-up. Emergency lighting batteries will power if the AC power fails for any reason. They are for back-up purposes only; they are
not powerful enough or large enough to be used for extended period of
time.
Having reliable, long-lasting emergency
lighting batteries is crucial for a suitable emergency evacuation plan. Providing back up batteries for exit
signs and emergency lighting is necessary for building compliance and
health and safety regulations.
Before you order emergency
lighting batteries, you need to check the voltage (v) and amperage (Ah) you
need. If you need any help, you can call us on 01702

Types of Emergency Lighting Batteries
LEDs are commonly used in emergency lights and exit signs in many
settings. They consume less than 5 watts
of electricity, making then a more cost-effective alternative to conventional
lights and exit signs with light bulbs. Their long lifespan also minimises
maintenance costs and improves safety. The
2 most commonly used battery types for LED emergency lighting are sealed lead
acid and nickel cadmium.
Lead Acid Batteries
Ni-Cd emergency lighting
batteries are actually preferred over cheaper, lead-acid batteries. A lead acid battery has a life expectancy of
5 -7 years as long as it is maintained at optimum temperature, whereas a Ni-Cd
battery lasts 10-15 years. NiCd
batteries have a much higher energy density and are also smaller and lighter
than comparable lead-acid batteries.
Nickel Cadmium (Ni-Cd) Batteries
Nickel Cadmium batteries are rechargeable,
operate with relatively low voltage of 6-12 volts and can give up to 90 minutes
or more of back up illuminating power.
They tend to be used in applications where long life, a high discharge
rate and economical price are important.
They are used as emergency
lighting batteries due to their resistance to temperatures. When exposed to extreme heat or cold other
batteries tend to lose their charge.
Ni-Cds can withstand temperatures between -40 to + 60 degrees Celsius.
Ni-Cd
Maintenance and Installation
1.
Ni-Cad batteries
are typically installed with wire leads that are permanently attached to the
batteries.
2.
When installing it is crucial to insure that they
are allowed to fully charge before power is interrupted. This is due to the memory effect - they'll remember
that maximum charge level as the full charge level possible.
3.
Units that contain NiCad batteries must be
tested monthly. Light units typically come with an integral
push-button switch that interrupts the power supply to the unit to facilitate
testing. If the light turns on the
system are working.
4.
A yearly test is also required where power
must be interrupted for a full ninety minutes, to make sure the battery is
still capable of maintaining a full charge.
5.
The annual test is actually good maintenance
for Ni-Cd emergency lighting batteries as they require
full depletion of charge at least once a year to ensure long- life.
6.
Make sure replacement emergency lighting batteries have the same
voltage and charge capacity. A lower
capacity will not ensure the full 90 minutes of light.
7.
You cannot replace
lead-acid batteries with Ni-Cd also changing the circuit board. The two battery
types charge at a different rate, which requires slightly different circuitry
on the board.
