Lead-acid batteries have low cost, low price, small capacity and serious pollution. Lithium batteries have high cost, high price, large capacity and environmental protection. According to this statement, if you want to use lithium battery for charging, use acid battery if you are short of money. Use acid batteries for high power consumption and lithium batteries for low power consumption. Sometimes, like with a cell phone, you don't have a choice.
About the battery
A driver's license is required to drive an electric car, and a car driver's license is not required to drive an electric bike.
According to Article 19 of the “Road Safety Law of the People's Republic of China”, when driving a motor vehicle, you must obtain a motor vehicle driving license. engine conforly to the law. To apply for a car driving license, one must meet the driving license conditions stipulated by the Public Security Department of the State Council; after passing the examination, the traffic management department of the public security organ will issue a State Council automobile driving license; corresponding category.
In addition, drivers must operate motor vehicles in accordance with the permitted types of driving indicated on their driver's license; when operating a motor vehicle, they must carry their motor vehicle driver's license;
Energy performance
1. Lead-acid batteries (lead-acid gel batteries) are cheap and have stable performance. them. kind of battery.
2. Lithium-ion batteries (often called lithium batteries) are more expensive, but they have high specific energy, specific powerhigh icity, low self-discharge, no memory effect, good cycle characteristics and wide operating temperature range, no environmental pollution and other advantages.
3. Crystal gel batteries have high cost and stable performance. There are very few electric vehicles using this type of battery on the market. Only a few companies equip them with this high-performance battery. highest safety factor. The advantage of much longer service life than the first two types of batteries and the advantage of self-healing function also constitutes the leading position in the industry. The advantage is that lead acid batteries do not have them, and the disadvantages. Delamination of lead-acid batteries can be avoided.
Are the headphones for the CET-4 and CET-6 exams equipped with microphones and are they rechargeable? I don't want batteries, it's not respectfulEnvironment

Problem Description:
No. 5 What are the differences between different types of batteries like coin cells and AA batteries?
Analysis:
#5 and #7 are simply different sizes. Generally, No. 5 is called AA and No. 7 is called. AAA
5 The standard battery dimensions are: battery height 49.0 ± 0.5 mm, diameter 16.8 ± 0.2 mm.
The standard dimensions of No. 7 are: battery height 48.0 ± 0.5 mm, diameter 14.1 ± 0.2 mm.
There are dry batteries, lithium batteries, nickel metal hydride batteries, and nickel-cadmium batteries made into AA and AA batteries.
Common alkaline batteries (such as Nanfu Energy Ring, Duracell, etc.), the voltage of No. 5 and No. 7 is 1.5V, the capacity of No. 5 is 1.5V. approximately 2,400 mAh, also called LR06. , and the capacity of No. 7 isapproximately 2400 mAh 1300 mAh. Also called LR03.
Actually, there are other battery sizes such as: No. 1 (D type), the battery height is 59.0 ± 0.5 mm and the diameter is 32 .3 ± 0.2mm. in old-fashioned flashlights in the past, and is also called big battery.
There is also No. 2: Type C, with a battery height of 49.5 ± 0.5 mm and a diameter of 25.3 ± 0.2 mm. This type is relatively rare, but many exist in some lithium batteries.
Dear customer, the CET-4 and CET-6 exams use the most common radios, which usually use batteries. Just to pass CET-4 and CET-6, it is not necessary to buy such a good one. I only used a radio 25 years ago, finally managed to use it for the last time, haha. Batteries are no longer environmentally friendly, which is less polluting, even if the rechargeable lithium batteries you lied aboutdata can. bought and recycled, they still have to be thrown away in the end. Yes, pollution is significantly greater than alkaline batteries. Finally, batteries are not recyclable.
