Carbon Battery VS Alkaline Battery
Introduction:
Carbon batteries and Alkaline batteries are very common battery types around us. What is the difference between them? How should we choose in daily use? Let’s figure this out together!
In the previous article, Lithium vs Alkaline Battery, we have already introduced the characteristics of lithium and alkaline batteries. If you want to learn more, you can spend a few more minutes reading our article above. Today, let us focus on the difference between Carbon and alkaline batteries.
What do Carbon Battery and Alkaline Battery have in common?
They all belong to dry batteries. Among them, the Carbon battery is a standard dry battery in our daily lives. It also has two other names: carbon-zinc battery and zinc-manganese battery. They were born earlier. The Alkaline battery is a new type of battery invented after the widespread use of the Carbon battery. It also has a familiar name: alkaline zinc-manganese battery.
What are the characteristics of Carbon batteries?
Carbon batteries usually have a voltage of 1.5V, are cheap, and are very stable and safe due to their simple structure. They are usually designed as disposable batteries and are used in air conditioner remote control panels or low-power electric toys and model airplanes. However, since the production material contains the heavy metal element cadmium, it must be recycled at a designated location after use. Otherwise, if it is burned with domestic waste, it will pollute the groundwater and affect the local ecological environment. It is rarely used now.
What are the characteristics of Alkaline batteries?
Alkaline batteries usually have a voltage of 1.5V and are slightly more expensive than Carbon batteries. They are usually designed as disposable batteries or rechargeable batteries. They can be used in a broader range of scenarios than Carbon batteries and are suitable for some household appliances that require enormous power, such as shaving batteries. Shaver, electric remote control car, etc. It does not contain heavy metals and is more environmentally friendly than Carbon batteries. Before the popularization of lithium battery technology, it was trendy in the market.
Price comparison of Carbon and Alkaline
If you only consider disposable (non-rechargeable) batteries, alkaline batteries are usually 1.5-2.5 times more expensive than Carbon batteries, and if they are rechargeable alkaline batteries, the price is usually higher.
What is the difference between Carbon and Alkaline batteries?
- Their rated voltages are both 1.5V, but usually, the design capacity of Alkaline is more significant than that of Carbon batteries, which means that for the exact discharge requirements, Alkaline can have a lower depth of discharge, which is more beneficial to the cycle life of the cell, so we Alkaline is generally considered more suitable for higher power applications.
- Alkaline’s design capacity is typically 4-5 times that of Carbon batteries.
- Alkaline’s discharge time is typically 3-8 times longer than Carbon’s.
The structural differences between Carbon Battery and Alkaline Battery:

Conclusion: Should we choose a Carbon Battery or an Alkaline Battery?
- From an environmental perspective, there is no doubt that we should choose Alkaline batteries that do not contain heavy metal elements because it is more environmentally friendly.
- From the perspective of usage requirements, Alkaline batteries are more suitable for long-term, high-current power supplies, such as buzzers, electric toothbrushes, remote-controlled toy cars, etc. The Carbon Battery is ideal for short-term, smaller current power supply, such as remote controls, quartz clocks, low-power radios, etc.
- From the perspective of cost of use, although the price of Alkaline batteries is about 1-2 times that of Cabon batteries, considering that the service life of the latter is about 1/3 or ¼ of the former, purchasing Alkaline is more cost-effective in the long run. A good investment.
