Compared with other batteries, alkaline batteries have a longer shelf life, and even if stored for a long time, the loss of power is not significant.
Constant voltage:
Throughout the entire lifespan of the battery, alkaline batteries can provide a constant voltage output, ensuring consistent performance of devices that rely on stable power.
Diversity:
Alkaline batteries come in various sizes and specifications, suitable for electronic devices ranging from small tools to large appliances.
Conveniência:
As a disposable battery, alkaline batteries provide convenience for users who do not want to charge, and can be quickly replaced with new batteries when the battery is depleted.
Low power applicability:
Alkaline batteries are very suitable for low-power devices such as remote controls and wall clocks, which require a constant but low battery level to be maintained for a long time.
The shortcomings of alkaline batteries:
Unable to charge:
This type of battery is a disposable product that needs to be properly disposed of after use, otherwise it may cause resource waste.
Short lifespan:
The power supply time of alkaline batteries is limited and may only last for a few hours or require replacement after reaching a specific voltage level.
Not suitable for high power consuming devices:
For devices that require rapid and large amounts of power, alkaline batteries may quickly deplete and require frequent battery replacement.
Voltage Decrease:
During use, the voltage of alkaline batteries will gradually decrease, which may lead to unstable device performance and affect functionality.
Environmental problems:
Due to its one-time use, alkaline batteries contain toxic substances such as zinc, manganese dioxide, and potassium hydroxide.
Improper handling may cause environmental pollution.
Long term high cost:
Although the initial cost is low, a longo prazo, frequent battery replacement will lead to an overall cost increase.
