What is nicad battery cells?

Nickel-cadmium batteries cells convert chemical energy into electrical energy when discharging, and convert electrical energy back into chemical energy when charging.

Nickel-cadmium batteries are secondary batteries because the chemical reaction is reversible, so the battery can also be recharged.

The cathode (positive plate) of a nickel-cadmium battery is made of nickel hydroxide, and the anode (negative plate) of the electrode is made of metal cadmium.

An alkaline aqueous solution is used as the electrolyte between the two electrodes.

Advantages of Ni-Cad Batteries

Operating temperature range of -4 - 158°F

No sulfation associated with nickel cadmium (Ni-Cd) batteries

No shedding/loss of plate material

The best battery available for abusive or harsh environments

Low internal resistance

High rate charge and discharge rates are possible

Up to 10C discharge rates for short periods typical

Flat discharge characteristic (but falls off rapidly at the end of the cycle)

Tolerates deep discharges - can be deep cycled

Are Ni Cd batteries rechargeable?

The nickel–cadmium battery (Ni-Cd battery or NiCad battery) is a type of rechargeable battery using nickel oxide hydroxide and metallic cadmium as electrodes. ... A Ni-Cd battery has a terminal voltage during discharge of around 1.2 volts which decreases little until nearly the end of discharge.

Ni-Cd Battery Properties

Constant high-temperature operation

Temperature depending on the used emergency lighting unit (refer to respective emergency control gear data sheet)

4. Communication equipment: cordless phones, walkie-talkie

Nickel Cadmium Exit Sign Battery

LED Emergency and Exit Lights contain a Ni-Cd battery inside the unit. The first step in determining the functionality of an exit or emergency light is to perform a push-button test of the light. A button is located on the bottom or side of the emergency/exit light that, when pressed, activates the back-up battery system. You can determine if the battery needs to be replaced by holding the button down for at least 30 seconds. The problem with this preliminary test is that NiCad batteries discharge at 100% power until the very last moments of the battery's life. To clarify, if a Ni-Cd battery is down to 15% of its life, it will still discharge at 100% power as if it's fully charged. Therefore, to ensure that all emergency and exit lights in the facility are discharged for at least 90 minutes, it is recommended that the batteries be replaced every 3 years.
