Emergency Lights, NEMA4X Rated, Black, White, Nickel-Cadmium (NiCd), 6 Volt, Nickel Metal Hydride (NiMH) Products (2 items)

An emergency light is a lighting device with a battery backup that switches on automatically when a building experiences a power outage. Emergency lights are standard in commercial and high occupancy residential buildings, such as college dormitories. Most building codes require emergency lighting be installed in older buildings as well.

NEMA rated enclosures are intended for indoor or outdoor use primarily to provide a degree of protection against the entry of water during prolonged submersion at a limited depth. NEMA 12 enclosures are designed to prevent the ingress of dust, water, and oil.

The main housing of these exit signs and emergency lights is painted black or made from a black thermoplastic.

The main housing of these exit signs and emergency lights is painted white or made from a white thermoplastic.

The nickel–cadmium battery is a type of rechargeable battery using nickel oxide hydroxide and metallic cadmium as electrodes. The abbreviation NiCd is derived from the chemical symbols of nickel and cadmium. NiCd batteries have a longer shelf life of around 10 years. The NiCd batteries sold on this site are High Temperature NiCds batteries with outstanding charge/discharge characteristics at both room temperature and high temperature up to 70°C (158°F).

Warning: Batteries, battery terminals, and related accessories can expose you to chemicals including Cadmium and Cadmium compounds, which are known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to https://www.p65warnings.ca.gov.

6 volt rechargeable batteries are a type of battery that can be recharged and used multiple times. They are commonly used for devices that require a low voltage and a high current, such as game feeders, lanterns, emergency lights, and electric signs. 6 volt rechargeable batteries have several advantages over disposable batteries, such as saving money, reducing waste, and preventing short-circuiting.

There are different types of 6 volt rechargeable batteries, such as Sealed Lead Acid (SLA), lithium iron phosphate (LiFePO4), nickel metal hydride (NiMH) and Nickel-Cadmium (NiCD). Each type has its own characteristics, such as capacity, cycle life, weight, and price. For example, SLA batteries are cheap and durable, but heavy and bulky. LiFePO4 batteries are lightweight and long-lasting, but expensive and sensitive to overcharging. NiMH batteries are eco-friendly and high-performance, but prone to self-discharge and memory effect. Depending on the application and preference, users can choose the best type of 6 volt rechargeable battery for their needs.

A nickel metal hydride battery, abbreviated NiMH or Ni–MH, is a type of rechargeable battery. A NiMH battery can have two to three times the capacity of an equivalent size NiCd, and its energy density can approach that of a lithium-ion battery.
