Distinguishing common types of batteries on the market today

There are many different types of batteries on the market.

1. How to distinguish battery types by size

Currently, there are many types of batteries with different sizes on the market, commonly including batteries such as:

- AA battery (small battery): is the most common type of battery, often used in wall clocks, blood pressure monitors, electronic thermometers.

- AAA battery (chopstick battery): smaller than AA battery, suitable for low power consumption devices such as remote controls for air conditioners, TVs.

- C battery (medium battery): larger in size than AA and AAA batteries, often used in flashlights, musical instruments.

- D battery (large battery): is the largest battery among cylindrical batteries, suitable for devices that consume a lot of energy such as high-power flashlights, radios, transmitters.

- Button battery (coin battery, button battery): is a flat, round battery, small in size, shaped like a button, used in watches, music players.

2. How to distinguish battery types by components

2.1 Carbon battery

Carbon batteries are traditional dry batteries that work well in low power consumption devices with the following main features:

Composition: The cathode is zinc, the anode is manganese dioxide mixed with a mild acid electrolyte.

Advantages: Low cost, suitable for devices with low power consumption.

Limitations: Low power supply capacity, carbon batteries of some poor quality brands contain toxic chemicals such as lead, mercury, cadmium,.

2.2 Alkaline batteries

Alkaline batteries are a superior version of carbon batteries.

If you are wondering 'what is an alkaline battery?', it is an improved and superior version of the carbon battery, with a longer life, better power supply and higher capacity. This type of battery is commonly used in many household appliances.

Components: The cathode is zinc, the anode is manganese dioxide (MnO2), the electrolyte is potassium hydroxide (KOH), so it is called alkaline battery.

Advantages: Large capacity, can be used for many energy-consuming devices such as technology, household appliances, medical and personal care equipment.

Disadvantages: Higher cost than carbon batteries.

2.3 Lithium battery

Among the types of batteries, lithium batteries are often used in high-end electronic devices such as phones, laptops, cameras, etc. The information below will help you better understand what lithium batteries are.

Classify:

Lithium metal batteries are not rechargeable.

Rechargeable lithium-ion battery.

Advantages: High capacity, long life, stable power supply, optimized for specialized, professional equipment.

Disadvantages: Expensive, requires careful storage to avoid fire and explosion.

2.4 Rechargeable battery

Rechargeable batteries contribute to environmental protection.

Rechargeable batteries are an environmentally friendly choice that saves money thanks to their ability to be reused multiple times.

Composition: Can be nickel-metal hydride (NiMH), lithium-ion (Li-ion) or nickel-cadmium (NiCd).

Advantages: Reduces battery waste, environmentally friendly, long-term cost savings.

Cons: More expensive than disposable batteries, requires proper charger to maintain performance.

Each type of battery has its own advantages and disadvantages, depending on your needs. If you need a long-lasting, high-performance battery, alkaline or lithium batteries are a good choice. If you want to save money and protect the environment, rechargeable batteries are the optimal solution.

Learn and choose good batteries from reputable brands like Panasonic batteries to ensure stable and long-lasting device operation!
