AA and AAA batteries are probably the most common battery sizes for consumers today.
An Introduction to the Various Types of Available Smoke Alarms The risk that fire poses to life, makes installing smoke alarms very important. There are various types available in the market for you to choose from. Here is a brief introduction to a few varieties.
HomeQuicks Staff Last Updated: Sep 11, One of the most important installations in buildings for safety against fire are the smoke alarms. They became widely available in a huge variety in the United States since the s.
Once they were generally available, prices fell and their sale also increased rapidly. Since then the number of fatalities due to fire related accidents have dropped by half.
Smoke alarms are self-contained devices that can detect fire or smoke and set out an alarm as a warning for the occupants of a building to evacuate its premises. They detect fire at an early stage. This gives occupants ample time to evacuate the building that has caught fire. Hence, installing these alarms helps reduce the number of casualties to a large extent and ensures fire safety.
Also known as smoke detectors, they are typically enclosed in a circular disk-like plastic enclosure and are fitted to the ceiling. However, the shape may vary according to the make and the company. These sense smoke particles that are too small to be detected, like from fast burning fires like oil or fat fires, and set out an alarm much before the smoke gets too thick.
However, they are less sensitive to slow and smoldering fires that give off lots of smoke before the flaming fires are caused. They are the most widely available varieties and are also inexpensive. However, they are quite prone to setting off false alarms.
Optical Alarms These alarms are slightly more expensive. However, their advantage is that they are less prone to sending out false alarms.

They do not react to steam or cooking fumes produced in the kitchen or to the steam in bathrooms. They are effective in detecting smoke particles produced by slow, smoldering fires, that may be caused due to burning of foam-filled upholstery or PVC wiring insulation. However, optical alarms are slower in detecting fast flaming fires.
As the name suggests, these alarms use the technology of both the ionization as well as optical alarms.
Hence, they can detect a fast-flaming as well as a slow, smoldering fire. However, once there is thick smoke due to fire, these alarms come out of their silent mode and the ring out loud.
Some are interconnected so that smoke detected by one alarm in one room activates the ones installed in other areas of the house. There are smoke alarms for people with special needs.
For example, for people with hearing disabilities, there are alarms with emergency lights that flash once they detect smoke. Power for Smoke Alarms Smoke alarms run on batteries, mains electricity, or by a combination of both. The batteries need to be replaced every year.Many types of batteries employ toxic materials such as lead, mercury, and cadmium as an electrode or electrolyte.
When each battery reaches end of life it must be disposed of to prevent environmental damage. Batteries are one form of electronic waste (e-waste).
Our guide below will help you understand more about the various types of car batteries and identify the best fit for your vehicle. Starting, Lighting and Ignition Batteries. The vast majority of automotive batteries are Starting, Lighting and Ignition (SLI) batteries.
What is a Battery?
What is a Battery? Both the anode and cathode are types of electrodes. Electrodes are conductors through which electricity enters or leaves a component in a circuit. Take a look at these projects that use different batteries in different configurations.
Unlike most editing & proofreading services, we edit for everything: grammar, spelling, punctuation, idea flow, sentence structure, & more. Get started now! We categorized the batteries into three different sectors: household (rechargeable and non-rechargeable), industrial and vehicle batteries.
Household Batteries These are the most common types of batteries powering devices you use everyday. Research Paper on Various Types of Batteries BATTERY RESEARCH PAPER There are many kinds of batteries which consist of different materials in order to produce an electric charge.
Here are some of the most common batteries, what they consist of and how they work.
