Flat Round Batteries-Introduction,Size and Usage
There are countless different types of batteries. Either by its shape or its composition, the combinations are the most numerous.
Given the wide variety of different models, we may not buy the best battery that suits our needs. In addition, we can find sellers who do not specify what type of battery they are selling, so, conveniently, we know well the different types that there are.
In this post, we have tried to clearly outline the details of flat round batteries that exist on the market. There are not all of them there are quite a few missing, but it should be more than enough for our needs.
Below you have the table of contents to see the different types schematically and to be able to go to the model that interests you the most.
Smart Flat Round Batteries:
Smart flat round batteries are used in many devices such as watches, calculators, hearing aids, PDAs, computers, remote controls, pacemakers, and medical devices. There are many types of button batteries and their size and composition are varied.?
The most common are mercury button batteries, although the most interesting and ecological option is lithium button batteries, which do not contain polluting elements such as mercury or cadmium. Button batteries, like any other type of battery, must be recycled to recover the mercury they contain and avoid contamination.
Button Cell Battery Features and Benefits:
- Low cost per hour of use, they are very cheap compared to other types of batteries and provide high energy density.
- Uniform voltage discharge.
- Very low discharge temperature.
- High stability to changes in the environment, they work in a wide temperature range between -20 ° C and + 60 ° C.
- Good shelf life with a self-discharge of less than 1% per year. Its storage can be five times longer than other types of batteries.
Sizes of Flat Round Batteries:
There are different types of flat round batteries are available in the market. Here are the details:
The different types of alkaline button batteries have a voltage of 1.5 volts, and below are some models with their measurements.
1. IEC Code: LR54 and its Diameter is 11.6 mm
2. IEC Code: LR44 and its Diameter is 11.6 mm
3. IEC Code: LR43 and its Diameter is 11.6 mm
4. IEC Code: LR41 and its Diameter is 7.9 mm
5. IEC Code: LR9 and its Diameter is 15.6 mm
In the case of lithium batteries, the voltage rises to 3 Volts. These batteries offer a long service life and are ideal for intermittent high load applications. They can work in a high-temperature range.
There are also Lithium Thionyl Chloride button cells. In some models, the prefix TL appears and the main characteristic is that they have a voltage of 3.6 Volts.
They are used in electronics, for PCB mounting, and in water, gas, and electricity supply meters. Its useful life exceeds 10 years.
This type of battery has good resistance to shocks and vibration and has a better discharge behavior than alkaline ones. Its performance at low temperatures is good, and its electrical voltage is 1.55 volts.
Normally used for hearing aids and due to their sizes, they incorporate a plastic tab to facilitate their installation. Its voltage is 1.4 volts.
Summarizing, the following table shows the voltage comparison of the different types of button batteries:
Voltage and Composition:
- Alkaline: 1.5 volts
- Manganese Dioxide-Lithium: 3 volts
- Polycarbonate-Lithium Monofluoride: 3 volts
- Thionyl Chloride-Lithium: 3.6 volts
- Silver oxide: 1.55 volts
- Zinc-air: 1.4 volts
What uses flat round batteries?
Looking for flat round button cell batteries for your tech products? Even though it is a technology that is being replaced by lithium batteries, the truth is that many options continue to bet on this classic solution. At the end of the day, it is more comfortable, since you do not have to be connecting the gadgets in question to the current.
Now, how should this energy source be to offer differential performance? The key is to look at a number of certain aspects. Looking at variables like voltage or capacity can help you choose the most efficient unit. Thus, you will guarantee the purchase of a more durable and effective option.
Another aspect to assess is the number of units you want to buy. Obviously, the higher the quantity, the less the cost per unit of product. Taking into account that it is an element that you will end up using over time, it is always good to have spare parts in a drawer at home.
On the other hand, it is important to take precautions if there are children at home. Being small, they could be easily ingested if they are within reach. Even so, some models include a solution that consists of the inclusion of a kind of film that, when in contact with saliva, gives off an instantaneous unpleasant taste. Let’s find more about these flat round batteries.
Flat round batteries are commonly used to power small electronic devices such as watches, hearing aids, and other electronic equipment. There are also different chemical compositions and for each of them, there is a great variety of sizes.
These types of batteries are mostly used in several items like calculators, watches, and hearing aids. Most of these batteries contain silver, lithium, mercury, and other several hazardous wastes.
Silver and Mercury based flat round batteries which are dumped in incinerated or landfills will leak mercury will be leaked mercury toxins in the food chains and water supplies.
However, you need to know that these types of flat round batteries contain toxic materials and so it is not safe for children and pets. And therefore, you need to recycle properly. Recycling will also reduce the need to mine essential raw materials and other risks associated with extraction.
That’s everything you need to know about flat round batteries. Hope you have liked our post!
