Alkaline batteries are a popular power source. They are easy to use and meant for one-time use, so you cannot recharge them. However, a few special alkaline batteries can be recharged a little. You can find these batteries in many household items and professional tools, which shows how important they are in our daily lives.
People like alkaline batteries for several reasons. They are very powerful, last a long time, and cost less. Compared to other primary batteries, like carbon-zinc, alkaline batteries provide more energy and last longer, making them a good choice for everyday use.
Alkaline batteries are a kind of primary battery. They work by using a chemical reaction to produce electricity. This process cannot be reversed. Once the materials inside are gone, these batteries can’t make power anymore. You will have to change them when that occurs.
The battery’s voltage is very important. A regular alkaline battery gives off 1.5 volts, which stays strong for most purposes. You can connect several cells to create higher voltages, like in 9-volt batteries.
Inside an alkaline battery, electrons move between two pieces called electrodes. The negative electrode is made of zinc, and the positive electrode uses manganese dioxide. A substance known as potassium hydroxide electrolyte helps the electrons move. This movement creates electric current that powers your devices.
Understanding how manganese dioxide works in alkaline batteries helps us learn how these batteries function and last longer. Alkaline batteries operate through a chemical reaction inside them. In these batteries, zinc powder serves as the negative electrode, and manganese dioxide acts as the positive electrode. They also contain an alkaline electrolyte, which is made of potassium hydroxide.
When you use a battery, a reduction reaction occurs at the zinc electrodes. This reaction creates voltage and turns zinc into zinc oxide at the anode. The overall reaction in the battery creates electricity. Knowing how these chemical processes work helps us better understand alkaline batteries and shows us how long they can last.
If you know about chemical reactions, here are some formulas. They explain why alkaline batteries can provide power:
(1): Zn(s)+2OH−(aq)⇌ZnO(s)+H2O(l)+2e–
(2): 2MnO2(s)+H2O(l)+2e−⇌Mn2O3(s)+2OH−(aq)
When you blend them, the complete reaction appears like this:
(3): Zn(s)+2MnO2(s)⇌ZnO(s)+Mn2O3(s)
The life of alkaline batteries varies based on several factors. A key factor is how fast the battery is used. High-power devices, like cameras or toys, drain alkaline batteries quickly. This is not the case with low-power devices, like remote controls, which use the batteries at a slower rate.
Temperature plays a big role in how long alkaline batteries last. Extreme hot or cold temperatures can change the chemical reactions inside the battery, impacting how well the battery works and how long it will hold a charge.
Storage conditions matter a lot. When you look at how long alkaline batteries last, several factors come into play. Temperature changes are important. How often you use them also matters. Plus, the place where you keep them is key too. All these things help to understand the lifespan of alkaline batteries.

A CR2032 battery is a non-rechargeable (primary) lithium coin or “button” cell battery that is 20mm in diameter x 3.2mm in thickness. The CR2032 battery has a voltage of 3 volts and a capacity of up to 240mAh, depending on manufacturer specifications. The CR2032 is the most commonly used lithium coin cell battery.
The LIR (lithium-ion rechargeable) coin cell, also known as a button cell, is the most miniature, least expensive lithium-ion battery format. Rated at 3.7V, LIR coin cell voltages may be up to three times higher than traditional lithium metal batteries like Cd-Ni or MH-Ni types. The LIR2032 has a nominal voltage of 3.6 to 3.7 volts when fully charged. The “2032″ ” refers to its standard size, with a diameter of 20mm and a height of 3.2mm, the same size as non-rechargeable CR2032 lithium coin cell batteries.
LIR2032 and CR2032 batteries are coin-cell batteries with the same physical size and shape (20mm in diameter and 3.2mm in height), making them compatible regarding form factor. However, they have significant differences in terms of chemistry, voltage, rechargeability, and usage:
The primary difference between LIR2032 and CR2032 batteries lies in their chemistry and rechargeability. LIR2032 batteries are rechargeable lithium-ion batteries, while CR2032 batteries are non-rechargeable primary lithium batteries. Using the appropriate battery type for your device is essential to ensure proper performance and safety.
The difference is as follows:
The numbers behind CR represent the battery size. The first two are in diameter, and the latter two indicate thickness.
2032 = 20.0*3.2mm
2025 = 20.0*2.5mm
2025 is thinner than 2032, so the capacity is less, and the service life is shorter. CR2032 and CR2025 are 3V lithium manganese butt batteries. The voltage of the two is the same.
CR2032 can withstand a maximum continuous current of 20mA. In contrast, CR2025 usually can only withstand 10mA discharge current, so when selecting the model, it is necessary to match according to the actual current of your product.
The button battery model can be classified based on a single standard, such as structure, voltage, and dimensions, and composite buttons can be classified. Practical button lithium batteries are generally marked by structure and shape size.
