Nowadays, lithium batteries have permeated every aspect of life. Mobile phones, tablets, Bluetooth headphones, even electric toys – almost everything is powered by lithium batteries. So many people have raised the question: Are alkaline batteries outdated? Should they be completely phased out?
In fact, the answer lies in daily life: the TV remote control, smoke alarm, emergency flashlight in the home – all use lithium batteries, and people feel that they are “overused for the sake of size”. Changing them once means a lot of waste. Instead, a single ordinary alkaline battery can last for several months. The truth is that alkaline batteries have never been outdated; they were just overshadowed by lithium batteries. In the scenarios where they excel, they remain indispensable.
Three misunderstandings lead us to mistakenly believe that alkaline batteries “should be phased out”
This is the most common misconception. The core lies in confusing “total endurance” and “scene adaptability”. The 2026 practical test found that the high endurance of lithium batteries is more suitable for high-power consumption devices (such as cameras, game consoles), where these devices require continuous high-power supply, and lithium batteries can take advantage of this; but for devices like remote controls and clocks with low power consumption, the endurance of alkaline batteries is not inferior and is even more durable – a single ordinary alkaline battery can last for 8-12 months on a TV remote control, which is on par with the endurance of the same specification lithium battery, and costs much less.
Many people think that alkaline batteries are “one-time pollution”, but the truth is different now. Today, regular brands of alkaline batteries have achieved mercury-free and non-toxic production, meeting national environmental protection standards. They can be scatteredly disposed of along with household garbage, without the need for centralized recycling, and have extremely little environmental harm; there are also rechargeable alkaline batteries, which can be recycled up to 100 times with correct charging, saving 80% of the cost compared to ordinary disposable alkaline batteries, being both environmentally friendly and cost-effective, completely breaking the prejudice of “not environmentally friendly”.
The rapid iteration of lithium batteries attracts attention, but it ignores the “invisible upgrade” of alkaline batteries. It started from the zinc-carbon battery and was improved to solve the problems of short endurance and easy leakage; now there are high-capacity models, leak-proof models, and even rechargeable models, expanding the applicable scenarios – not only meeting the basic needs of home use, but also suitable for low-power devices in industrial and medical fields, and its stable power supply characteristic is something that lithium batteries cannot replace for the time being.
The birth of alkaline batteries originated from a “small improvement” by chemist Lewis Yu. The early zinc-carbon batteries had short endurance and were prone to leakage, often damaging the equipment. Lewis Yu optimized the electrolyte formula inside the battery, replacing the acidic electrolyte with alkaline electrolyte, significantly improving endurance and stability. Thus, alkaline batteries were born.
Its evolution has never stopped: from the initial disposable model to the current rechargeable model; from ordinary capacity to high-capacity models (capacity up to 2300mAh); from simple sealing to the current multiple leak-proof processes. Each upgrade step has been in line with the needs. And its core advantages – stable voltage and resistance to storage – have remained unchanged, which is also the key to its survival: in a room temperature and dry environment, alkaline batteries lose only 2-3% of their power each year, and can still function normally after 3 years. This is something that lithium batteries cannot match.
The 2026 practical test verified that alkaline batteries have an extremely low self-discharge rate in a room temperature and dry environment, losing only 2-3% of their power each year, with a shelf life of 5-10 years, and can still supply power normally after 3 years. This point is particularly suitable for emergency scenarios: smoke alarms, emergency flashlights, backup remote controls, etc. These devices are not frequently used but need to be kept powered at all times. Alkaline batteries do not require frequent replacement and can be regarded as “emergency essentials”.
An average family needs approximately 50 batteries per year. A single ordinary alkaline battery costs only 1-2 yuan, and the annual cost is no more than 50-100 yuan. While the cost of the same specification lithium batteries is 5-8 yuan, the annual cost is 250-400 yuan. Alkaline batteries can save more than half of the cost. Moreover, alkaline batteries can be purchased anywhere, such as convenience stores and supermarkets, without the need for special online shopping and waiting. They are suitable for the daily needs of ordinary families.
Compared to lithium batteries, alkaline batteries have more prominent safety features. The regular products adopt a sealed leak-proof process, without mercury or toxicity, and will not cause equipment damage due to leakage, overheating, or bulging; at the same time, no special charger is required, and they can be replaced directly after use (except for rechargeable models). The elderly and children can easily operate without having to remember the charging time, and there is no need to worry about overcharging and damaging the battery.
Tests have shown that alkaline batteries can still perform stably in the temperature range of -20°C to 60°C. The adaptability to high and low temperatures of alkaline batteries far exceeds that of lithium batteries. Whether it is an outdoor flashlight in the northern winter, a small device in the vehicle, or an indoor appliance in the southern summer, alkaline batteries can provide normal power supply. While lithium batteries’ battery life will significantly decrease in extreme temperatures and may even be unusable.
Many people think that alkaline batteries will be phased out, but the data does not lie. In 2024, the global market size of alkaline batteries reached 8.9 billion US dollars, and it is expected to exceed 14.3 billion US dollars in 2033, with an annual growth rate of 5.5%, steadily growing behind the support of essential scenarios. In 2024, the global production of alkaline batteries reached 1.5 billion cells, with the annual consumption in the Asia-Pacific region exceeding 6 billion cells, and there is a strong demand for home and industrial (medical, manufacturing) applications – low-power devices in the industrial field and small instruments in the medical field all cannot do without the stable power supply of alkaline batteries.
Future trends: Major manufacturers are focusing on the environmental upgrade of alkaline batteries, aiming to reduce carbon emissions by 30% by 2030; at the same time, they are continuously iterating high-capacity models to adapt to more new devices and further expand application scenarios. The market demand for alkaline batteries will continue to grow.

Usage tips: Extend lifespan and be more convenient
Alkaline batteries are essential rather than “outdated products”
Tests have proven that alkaline batteries have never been outdated. They do not have the high luster of lithium batteries, but in low-power, emergency, home, and industrial scenarios, with their high cost-effectiveness, stable power supply, and safety and convenience advantages, they are always indispensable. Lithium batteries and alkaline batteries are not “either-or”, but have their respective applicable scenarios: for low-power, infrequently used, and emergency equipment, prioritize alkaline batteries; for high-power, frequently used equipment, consider lithium batteries.
Rather than blindly pursuing “new technologies”, it is better to choose the appropriate battery based on the requirements of your own equipment. Selecting the right alkaline battery can not only save you trouble and money, but also meet your daily needs. This is the most practical choice.
