What types of batteries are used for emergency lighting?
Various different types of batteries are used for emergency
lighting. The main types are:
--Lead-acid. Until recently, they were commonly used in stand-alone
emergency lighting installations, such as dual spotlights, and are
still widely used in central battery systems. Outside of these
specific applications, lead-acid batteries are now rarely used for
emergency lighting.
-- Nickel Cadmium (NiCd). Cadmium is highly toxic and is one of
only six substances banned under the EU RoHS directive. However,
batteries in emergency lighting are exempt because until recently
there were no suitable alternatives. NiCd batteries are widely used
in stand-alone emergency lighting equipment and emergency
conversion kits.
-- Nickel Metal Hydride (NiMH). These batteries are widely used in
emergency conversion kits in place of NiCd batteries, and in some
applications they have some (slight) advantages.NiMH batteries are
thinner than NiCd batteries.
-- Lithium. Lithium batteries are available in a wide variety of
types and are increasingly used in emergency lighting applications.
They offer many advantages over lead-acid, NiCd and NiMH, so their
use is rapidly increasing.
What Is the Difference Between Ni-Mh Battery and Li-Polymer
Battery?
Ni-Mh Battery is composed of hydrogen ion and nickel metal, and the
power reserve is 30% more than Ni-Cd battery, and it is lighter, no
pollution to environment, has longer service life. Its disadvantage
is the price is much more expensive, performance is worse than
Li-Polymer Battery.
Lithium battery is a kind of battery made of lithium metal or
lithium alloy as anode material and uses non-aqueous electrolyte
solution. Now it has become the mainstream.
Rechargeable Lithium Battery has small volume, light weight, low
self discharge rate, no memory effect, it is widely used in many
new mobile devices.
The lithium battery is small and has large specific energy, the
voltage of a single lithium battery is 3 times of Ni-Mh battery.
Without memory effect, it can be used with the charge. But also can
not use a charge, number of charging and discharging too much will
affect the battery life. Lithium battery should not be stored for
long time, or it will lose part of capacity forever.
