All emergency lighting and lighted emergency exit signs use a battery for powering the lamps. In order to assure continuous openness and operation of the emergency light, these batteries are rechargeable. Circuitry within the emergency light charges the battery also covers that it remains charged.
As Emergency Lighting Battery Supplier, today we briefly explain the relevant knowledge about the product.
There are two types of batteries that are used for emergency lights; they're:
Sealed lead-acid batteries (the Exact Same type used in automobiles) and Nickel-cadmium batteries.
Sealed lead-acid batteries would be the oldest rechargeable technology accessible. They're called lead-acid because they contain lead metal plates, immersed in acid. The acid breaks down the plates, producing the charged electrons that are electricity. More recently, technology of lead-acid batteries has improved, allowing for completely sealed components, that don't require the inclusion of water to keep the acid level.
Emergency Lighting Battery Ni-Cd would be the very first ever "dry" (no acid required) rechargeable batteries. Since then, other technologies have been developed, but they are generally more expensive. In a nickel-cadmium battery, the 2 metals are separated by a dielectric (non-conductive) layer, causing the metals to magnetically react with one another, producing the electrons that form electricity.
