Combo exit signs are devices that combine an exit sign and emergency lights in one unit. They are used to indicate the direction of the nearest exit and provide illumination in case of a power outage or emergency situation. Combo exit signs are required by building codes and fire safety regulations in many public and commercial buildings, such as apartment buildings, medical facilities, restaurants, schools, hotels, and offices.

Combo exit signs can be mounted on the wall, ceiling, or side of a building, depending on the layout and design of the space. They come in different colors, shapes, and sizes to suit various preferences and needs.

Combo exit signs are energy-efficient, durable, and easy to install. They have a battery backup feature that allows them to operate for at least 90 minutes in the event of a power failure.

Combo exit signs are an essential safety device that can help people find their way out of a building quickly and safely in an emergency.

Red letters are required for New York City and Chicago approved exit signs.

Rechargeable batteries are batteries that can be recharged and reused multiple times. They are more environmentally friendly and cost-effective than disposable batteries. One of the most common types of rechargeable batteries is the 12 volt battery, which is often used in backup power supplies, LED lights, CCTV cameras, and other devices that require a steady and reliable power source.

12 volt rechargeable batteries come in different sizes, capacities, and chemistries. Some of the most popular chemistries are sealed lead acid (SLA), lithium ion (Li-ion), and lithium iron phosphate (LiFePO4). Each chemistry has its own advantages and disadvantages, such as weight, lifespan, performance, and safety. For example, SLA batteries are heavy and have a short cycle life, but they are cheap and easy to maintain. Li-ion batteries are light and have a high energy density, but they are expensive and prone to overheating. LiFePO4 batteries are stable and have a long cycle life, but they are costly and have a lower voltage than other lithium batteries.

Commercial lighting is lighting used for commercial spaces such as offices, stores, institutions, hospitals and government buildings, essentially those spaces that are not residential, industrial or for manufacturing.

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.

Sealed lead acid batteries are sometimes referred to as VRLA (valve regulated lead acid) and there are two primary types AGM and Gel. We offer both AGM and Gel batteries, each has its advantages over the other depending on the specific application. SLA batteries usually last between 3 to 5 years with typical usage. The optimum operating temperature for the lead-acid battery is 25°C (77°F). Elevated temperature reduces longevity. As a guideline, every 8°C (15°F) rise in temperature cuts the battery life in half.
