Have you ever found some doubts when you buy or use batteries? There are many types of batteries in supermarkets, and the shapes and sizes of these batteries are almost the same. You may not know what to do for a while.
And why alkaline batteries are called superior battery types? How to choose the kind of battery that is most suitable for your electrical appliances? If you read this article, you are very lucky. As an expert with 20 years of experience(self-introduction), I will elaborate on the differences and advantages of alkaline batteries and other types of batteries from several different aspects.
#1 – First of All, What an Alkaline Battery Is?
Alkaline batteries are disposable dry batteries, the main raw materials are zinc, manganese dioxide, and steel shell. Chemical energy is converted into electrical energy. Because the electrolyte becomes alkaline, it is also called an alkaline zinc-manganese dry battery. The types of alkaline batteries are usually used: LR6/AA battery, LR03/AAA battery, LR14/C battery, LR20/D battery, 6LR61/9V battery, 23A battery, 27A battery, AG13/LR44 battery, etc. Most alklaine batteries voltage is 1.5V, 23A and 27A is 12V, 6LR61 is 9V.
#2 – What Is the Difference Between Alkaline Batteries and Nickel-Metal Hydride Batteries and Lithium Batteries?
- Alkaline batteries are disposable dry batteries. Although individual manufacturers claim that alkaline batteries can also be recharged, they are in fact immature and unscientific.
- Ni-MH batteries and lithium batteries are rechargeable batteries, and these two types of batteries are secondary batteries.
- In terms of price, rechargeable batteries are higher than alkaline batteries.
- In terms of capacity, generally, rechargeable batteries are higher than alkaline batteries.
- From the perspective of self-discharge, the self-discharge rate of alkaline batteries is much lower than that of rechargeable batteries, so alkaline batteries are generally used as backup emergency batteries.
#3 – Alkaline Batteries vs Zinc Carbon Batteries?
Alkaline batteries and carbon batteries have the same chemical reaction principle. The main cathode material is manganese dioxide, and the main anode material is zinc.
Alkaline batteries are composed of basic (alkaline) electrolytes of potassium hydroxide. Zinc-carbon batteries are composed of acidic electrolytes of ammonium chloride and zinc chloride. Higher purity and activity in manganese dioxide offer better performance compared with the carbon-zinc batteries. These cells are available at an output voltage of 1.5 volts but at a higher energy density of 6.5-watt-hours per cubic inch. The features that make this alkaline battery most suitable include better energy density compared with zinc-carbon battery, low discharge with a shelf life of nearly 5 years, efficiency in low-drain, medium-drain, and high-drain applications, and better performance at wide temperature ranges and hence, are likely to be used even in cold conditions.
#4 – What Are the Advantages of Alkaline Battery?
Alkaline battery is relatively cost-effective. Compared with rechargeable batteries such as nickel-metal hydride and lithium battery, alkaline battery are cheaper.
Compared with carbon batteries, although the price of alkaline batteries is generally more than twice that of carbon batteries, under the same discharge conditions, the use time of alkaline batteries is more than twice that of carbon batteries.
Another advantage is that alkaline batteries can work in extremely cold and extremely hot environments. Carbon batteries do not. The hotter or colder it becomes, the lower the efficiency of the battery.
Alkaline batteries are more environmentally friendly, and they do not contain lead, mercury and cadmium, which are the advantages of alkaline batteries. Alkaline batteries can easily pass the ROHS test. Non-alkaline batteries may even need to be handled in a specific way to prevent contamination. Alkaline batteries can be used as ordinary garbage and then thrown away. You don’t need to worry about the environmental pollution caused by throwing away alkaline batteries.
Many times make alkaline batteries easier to use than non-alkaline batteries.
