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.
