Recommended models: Energized Ring, Adventurer Lithium Iron
 
Nanfu is the largest alkaline battery manufacturer in China and the fifth largest in the world, accounting for more than half of the market share in China. Nanfu alkaline battery has ranked first in the industry in terms of quality, sales, economic benefits and labor productivity for 18 consecutive years. As a result, it ranked 399th in the 2018 "China's 500 Most Valuable Brands" list by the World Brand Lab.
 
Nanfu's energy ring successfully used advertising to pry open the door of thousands of households, erected the brand image of alkaline batteries, and became the most familiar battery brand among Chinese people, but in fact, the energy ring itself did not bring power to the battery, and the symbolic meaning was greater than the actual value. Nanfu has the best offline channels in the domestic battery market, which is convenient for us to find Nanfu batteries in large and small supermarkets, which is the best choice for offline purchases and emergency purchases.
 
Nanfu pays more attention to scientific research capabilities, with more than 450 senior and intermediate professional and technical personnel, and has a national technology center and a postdoctoral research station. Nanfu not only ranks first in Asia in terms of dry battery sales, but also has easily surpassed Panasonic and other companies in terms of button battery sales on e-commerce platforms such as Tmall.
 
The well-known Nanfu energy ring is an alkaline battery, although the power performance is not outstanding among many alkaline batteries, but the safety, stability and environmental protection have been at the forefront of the industry, and the shelf life is up to 10 years.
 
Nanfu Adventurer lithium iron battery only launched the No. 5 battery, with a shelf life of up to 15 years, which is higher than the 10-year shelf life of Shuanglu, and has a technological advantage. This lithium-iron battery is 34% lighter than a regular alkaline No. 5 battery and has an extremely high energy density. On top of that, it has excellent cold resistance and can work at minus 40°C. However, the low-temperature performance of general alkaline batteries is not very good, because the temperature reduction will inevitably reduce the conductivity of the electrolyte, resulting in the inability to discharge current or the capacitance is greatly reduced. In addition, the included battery pouch is IP68 waterproof, which can reduce the probability of accidents in harsh environments.
 
If you deal with dry batteries more, Nanfu also has a battery tester, which can quickly judge the power of the battery, and the price is only 10 yuan.
