Batteries are commonly used by most households across the world. They are simply put portable packs of power. They are commonly used use in our mobile devices, smartphones, laptops, cameras, clocks, remotes, drones, remote-based children’s toys and so on. We owe a lot of credit to batteries for our progress and development since without it many of our inventions and ingenuity would not have remained paper dreams.
In recent times we have a wide range of size and shapes in batteries ranging from the humongous megawatt batteries which are capable of storing large amounts of power collected from solar panels, windmills etc which are capable of supplying electricity to either an individual home to an entire village while conversely there are our button batteries which power our watches. Batteries are so much involved in our day to day lives that we often overlook them as if they were omnipresent.
Human beings have made exponential progress and advancements in technology in the last century. A significant amount of this progress was dependent and ever reliant on the availability of power. From the Baghdad battery to our modern-day batteries, the technology has kept on improving.
A battery is basically portable storage which stores electric storage in its cells. The battery converts chemicals into electricity through the process which is known as electrochemistry. In a flashlight, the electric current is carried from the cell to the bulb which eventually emits a source of light.
Batteries are composed of cells ranging from single-cell to up to six cells and they are measures of voltage the battery can carry. The size of the battery is usually denoted by ratios such as AA, AAA, C and D. There are also other terms associated with batteries such as single-use batteries are termed as CR2 battery.
Batteries are available in various capacities, voltages, sizes, shapes, and colors depending on the manufacturer. There are different compositions of batteries such as Nickel Cadmium (NiCd), Nickel Metal Hydride (NiMh), Lithium Polymer (LiPo), and Lithium-Ion (Li-ion). These are the commonly used battery compositions in most devices which work on batteries.
In recent times there has been a great demand for rechargeable batteries simply because they very cost-effective as they can be re-used several times as compared to single-use batteries. The rechargeable batteries are termed as RCR123 or RCR 123A battery.
There are several brands which provide a wide range of batteries such as Duracell, Enegitech, Energizer, Panasonic, Rayovac among others. They develop batteries such as the CR2, RCR, and CR123A battery as well.
Below are some simple terms we highlighted the factors which will help you choose the best battery for your flashlight:
- Price is not the standard for Long lasting flashlight battery:
Batteries come in various power ratios. Generic batteries are cheap but they do not last long periods of time. Major brands are expensive but that also does not mean they will last long. Batteries are measured in mAh (milliampere-hours). The higher the mAh the longer it will last.
- Battery composition:
Lithium-based batteries and Nickel Metal Hydride have extensively used compositions because of their long-lasting capacity.
- C Rating:
C Rating denotes the rate at which the battery will discharge its power. The higher the C rating the longer will the battery last.
- Migrate to Rechargeable batteries:
Rechargeable batteries can be reused several times and they come in various sizes and capacities making them a wise choice for a flashlight. There are many reputed brands which offer high-quality rechargeable batteries; Enegitech is one of them which offer a wide range of rechargeable batteries at best.
