24 battery models competed, Nanfu lost, who is the real energy ring? [Copy link]

 

I was shaving halfway when the battery of the razor I had just replaced died again…I took some time to lie down on the weekend, and the baby’s train, remote control car, airplane, early education machine, and reading bear all died…The only sound in the world was the baby’s crying! The sound of noise!

Don’t underestimate batteries. You will regret not having enough batteries when you need them. Batteries are used up too quickly and you will get angry. With the belief that everything can be tested, we will test batteries this time…10 types of No. 5 batteries and 14 types of No. 7 batteries will be tested together. Which one is the king of durability?

There is a saying at the beginning, although battery evaluation is simple, liberal arts students may not be able to understand it... I think there is no need to embarrass myself, just take the result!

The evaluation will compare the performance of the batteries through three experiments↓

Battery capacity test

Battery discharge time test

Battery endurance test

The test is carried out according to the national standard experimental conditions, but the actual application conditions will be different, so we have added an experiment that is more in line with the actual conditions——The small train runs in circles.

Come, please open the junior high school physics textbook Chapter 5 Voltage Resistance and Current, and review the past middle school (junior high) exam (love) time with me.

First, let's talk about the physical formula

Voltage U = Current I × Resistance R

The circuit diagram is as follows↓

The review is over, and it's time to get into the actual combat.

No. 5 battery PK

Battery capacity test

Battery capacity refers to how much power the battery can store. In theory, the larger the battery capacity, the longer the working time. The purpose of the experiment is to accurately measure the battery capacity.

Battery capacity is generally calculated in ampere-hours, that is, discharge current (constant current) I×discharge time (hours) T.

Experimental equipment: ITECH capacitance tester

Reference standard: "GB 8897.2-2013 Primary Battery" Part 2 Dimensions and Electrical Performance Requirements Chapter 6.1.1.

Actual measurement results of battery capacity↓

Batteries with a capacity of more than 2.000Ah include: White Elephant, Changhong, Shuanglu, Super, Duracell, Amazon Baseus! Battery discharge time test Referring to the national standard, we use real-time discharge measurement to test the battery discharge performance. Experimental equipment: DCF-1 battery discharge measurement table 344411 During the discharge of the battery, the voltage U will gradually decrease with the passage of time. The lowest cut-off voltage is 0.9V. At this voltage, the battery has stopped working and the output current is basically 0.

Reference standard: "GB 8897.2-2013 Primary Battery"

Actual test results of battery discharge time↓

The batteries with discharge time exceeding 6 hours are: Amazon Baseus, Beacon, Speedmaster, White Elephant, Double Deer, and Duracell.

Combining the above two experiments, the battery capacity is greater than 2.0Ah, discharge time greater than 6 hours, there are 5 batteries that successfully entered the recommended candidate list: White Elephant, Double Deer, Super, Duracell, Amazon Baseus. Pictures speak louder than words↓

Battery endurance test

The above are all test values under theoretical conditions. Who is the king of endurance in actual use? Come, this is a test that allows you to intuitively feel the battery endurance and durability. Please select the 5 batteries below for a "Train Running Circle Showdown"!

Experimental equipment: toy train, tape measure, laser digital display electronic counter

Experimental method: Put new batteries into the train, and let it run in circles. The one with the most laps wins

The train will run in circles until the end of time and until the battery is exhausted. The laser digital display electronic counter in the picture will honestly record the number of laps the train has run↓ (please ignore the thermos cup in the upper left corner, it is not mine, I am still a baby)

[attach]344414 [/attach]

I would like to express my special thanks to Xiaolong Bao and Jing from the rest assured evaluation group for providing the train for the experiment.

The results of running laps↓

Amazon Baseus 3975 laps

Supra 3523 laps

Shuanglu 3485 laps

Duracell 3261 laps

White Elephant 3157 laps

The mileage converted into is as follows↓

For detailed data summary, please refer to the table below↓

No. 7 battery PK

The No. 5 battery PK has come to an end. The No. 7 battery was also tested for battery capacity, discharge time, and cruising range (small train running laps) using the same method. The experimental process will not be expanded, and the results are directly shown↓

Detailed experimental data of No. 7 battery↓

Which battery can make the remote control last longer?

The discharge time of the battery is different under different discharge currents. That is to say, in a competition between batteries A and B, battery A may run longer than battery B when used as a train, but battery B may last longer than battery A when used as a remote control~

The maximum working current of the remote control is only 200mA, while the working current of the train is 350mA. Due to the different currents I, the amount of electricity consumed in the battery is different: Q=I×I×R, the amount of electricity allocated to the device by the total battery energy will change, and the actual working time is directly related to the working current of the device.

As the most battery-reliant household gadget, it is necessary to recommend a longest-lasting battery for the remote control.

You don't have to understand the calculation process↓

The quiescent current of the remote control is 0.5uA, and the working current is 100-200mA. Based on this, we can estimate the power consumption of a week:

Assuming that you press the button 50 times a day, each time for 1 second, in a week it will use about 100x50x7x1/3600 mAh =10mAh,

200x50x7x1/3600 mAh =20mAh, a quiescent current of 0.5uA is used in a week

0.5/1000x24x7=0.084mAh, the two numbers add up to approximately 11mAh-21mAh.

Battery capacity/weekly power consumption of remote control = number of weeks of use

Take two Shuanglu batteries as an example: 906mAh*2=1812mAh

1812/21=86 weeks/52=1.6 years

Result↓

▲Remote controls generally use AA batteries

▎Perhaps you have wondered why a battery with a short discharge time can run a train for a longer time?

Take Changhong No. 5 battery as an example. Although Changhong's discharge time is short, it may be because the battery itself consumes less power, so more energy is allocated to the toy train, and the train can run more laps.

Which battery can last longer for the remote control?

The discharge time of the battery is different under different discharge currents. That is to say, in a competition between two batteries, A and B, the train may run longer than B, but B may last longer than A in the remote control~

The maximum working current of the remote control is only 200mA, while the working current of the train is 350mA. Due to the different currents I, the amount of electricity consumed in the battery is different: Q＝I×I×R, and the amount of electricity allocated to the device by the total energy of the battery will change. The actual working time is directly related to the working current of the device.

As the most battery-dependent household essential, it is necessary to recommend a most durable battery for the remote control.

Hello baby! Nanfu is completely defeated. It seems that I can give up in the future?

cruelfox

Alkaline battery remote controls have only been used for less than two years? I doubt this conclusion. Electric toys, shavers... Why don't they use NiMH batteries?

star_66666

It seems that I can no longer buy Nanfu since it was acquired by Gillette.

yuhon

Is it real? Or is it just an advertisement?

Orima

Thanks for sharing! It is worth a reference. Nanfu should be good at advertising...

轩焱森

Since we have tested everything, why not test other types of batteries, including rechargeable batteries?

sint27

I haven't used many batteries, but my experience shows that Nanfu is more durable than Baixiang.

ddllxxrr

I have old ideas and I am stubborn. I just like Nanfu and I can't buy anything else

whuer

Haha, it's the same as a mobile phone review. If you collect the right money, you will praise whoever collects the money, and if you want to frame whoever you want, you can frame whoever you want, haha.

It may be like that. We just want to understand the conditions, methods and content of the test.

bobde163

I can't believe that Nanfu batteries are at the bottom of the list. Could it be that I bought a fake Nanfu? There are many fake Nanfu batteries on the market now.

I wrote a paper about Guanyu batteries before, but I have never done an experiment like yours. The conditions are very simple. Strictly speaking, your test may still have some problems. The age of the battery affects the test. The temperature conditions must be consistent. The battery current must be limited to the range allowed by the battery.

qwqwqw2088

Mo Shuang Yue Bi published on 2018-2-8 16:09 I used to write papers on Guanyu batteries, but I have never done an experiment like yours. The conditions are very simple. But strictly speaking, your test may still be...

How did you test the battery when writing the paper? How were the capacity and discharge tests conducted at that time? The endurance test methods are generally different.

魔双月壁

Specialized charging equipment, discharging equipment, constant temperature box, etc. The problem is that I have never seen a paper about electric vehicle battery management.

Batteries produced at different times will also have differences in performance, so you should try to choose products with similar production dates for testing.

2AH 能跑6小时，也就是 0.34A，这玩具还是比较省电的，
你拿个遙控车（不是玩具，是航模店卖的那种）试试，金霸王，GP超霸，劲量，永备，都是5号，统统半小时不到就蔫巴了，其他品牌在香港买不到，所以测试不了，
另外也做过短路实验，以头发粗细的铜线把正负极连起来，这四种电池都能把铜线烧红，金霸王最厉害。

Generators, power generation, photovoltaics, and temperature difference energy all require an instigator to generate electricity. The power generation components of chemical batteries are built-in and are the most portable power source. However, for power and lighting, the battery life is too poor!
