汽车电池如何工作？
汽车电池可充电，并为您的车辆提供必要的电流。基本上，电池为汽车的启动器提供了进食，这促使发动机启动。如果汽车电池没有足够的果汁，则不会启动发动机。
理想的汽车电池放大器评级
Car Battery Capacity measured in Amp Hours
汽车电池容量已列在安培小时(Ah). This describes the number of amps a battery provides over 20 hours without dropping below the required voltage.
储备容量
储备容量表明，充满电的电池能够交付25A并保持适当量的电压。这个数字最重要的是深循环电池.
CA/MCA
The cranking amps or marine cranking amps show the maximum current from a fully charged 12V over thirty seconds at 32 degrees Fahrenheit. It’s most often used with marine batteries.
CCA
Cold cranking amps shows the maximum current from a fully charged 12V battery over thirty seconds at zero degrees Fahrenheit. It’s used most often for passenger vehicles that needbatteries for cold weather.
Hot Cranking Amps
Shows the amount of current that a battery can provide over thirty seconds at eighty degrees Fahrenheit. This number is valuable when evaluating thebest battery for warmer weather.
脉冲热曲柄放大器
该值显示了华氏77-80度之间的三到五秒钟以上的最大电流。总体而言，它可以测量汽车电池的强度。
启动汽车需要多少安培？
Most fully charged automotive batteries are designed to work with a particular engine, but how many amps is a fully charged car battery? The amps you need to start your car engine will depend on what model you drive. The ambient temperature and voltage will also adjust this value. Most times, a car will require between 400 and 1000 amps to start and power up the electronics.
However, in some cases, having 300 amps might be enough to start the car engine, especially if you drive a compact vehicle. Your vehicle’s owner’s manual should tell you what type of battery is needed to run your car correctly.
如何测量汽车电池放大器
你可以使用万用表检查汽车电池安培. Once you know - how many amp-hours is a car battery – you will be able to tell if your battery is working correctly.
Here’s a helpful video to get you started.
如何为汽车电池充电
There are many ways to recharge your car battery, from providing a快点开始使用一个maintainer. If you plan to use a maintenance charger, connect the equipment to the appropriate sides of the battery. Make sure you have the settings correct on the unit and turn it on. With something that automatically turns itself off, you won’t have to worry about overcharging. If the battery doesn’t hold a charge, you might consider replacing it or trybattery reconditioning.
人们也问（常见问题解答）
电池的放大器评级会随着时间而变化吗？
If the battery is in proper working condition, you should receive the specified amp rating every time.
How quickly does a car battery charge while you’re driving?
It depends on the electrical system and battery in your vehicle. For the most part, a ten-mile highway drive should be enough to charge most batteries completely.
How many amps does it take to start the engine?
The majority of cars require between 400 and 1000 amps to start, but each vehicle has different specifications. Check the owner’s manual to find out how many amps and volts the car battery is.
12伏汽车电池有多少个安培？
Most car batteries have a capacity of 48Ah, meaning it will deliver one amp for 48 hours. However, answering the question - how many amps is a normal car battery – will depend on what type of vehicle you drive.
How many amps do you need to charge the car battery?
The basic car charger operates around 2 amps, meaning it would take 24 hours to fully charge a dead 48Ah battery.
Is it possible to use a charger with higher amps?
一旦您弄清了多少个安培电池，您就想选择兼容的充电器。但是，您可以使用不需要损坏电池而提供的放大放大器的功能多。只需确保您不会过度充电电池即可。
Can I leave car battery charger on overnight?
If the battery charger features safety precautions that keep your battery from getting overcharged, you could leave it on overnight. Otherwise, you want to remove the charger as soon as the battery is fully charged.
结论
So, how many amp hours is a standard car battery? Now you know that the figures change based on the vehicle you drive. However, you should have a better understanding of how to protect your car battery and keep it working correctly.
