There are two ways to look at the battery model of an electric vehicle:
The first is the charger's output current. Look at the output voltage **V DC **A on the charger, that of 36 V is: the output voltage is 36 V - 42 V DC**A if it is 1.5 A then it is 10 Ah if it is 1.6 A; , then it is 12AH; 48V: Output voltage 48V--59V DC**A.
The second is to open the battery case and count how many batteries there are. If there are three batteries, they are usually 36 V. Once the voltage is determined, determine the capacity. If the battery says 6-DZM-10, it is 10AH, if it is 6-DZM-12, it is 12AH, and so on.
Classification of electric vehicle battery models. Generally, there are four types of electric vehicle batteries: 24V, 36V, 48V, 60V and 64V, of which 36V and 48V are the most common.
The commonly used 36V are: 36V10AH and36V12AH. Some of them are also 36V14AH, 36V17AH and 36V20AH. Commonly used 48Vs are: 48V10AH, 48V12AH, 48V14AH, 48V17AH, 48V20AH.
The models mentioned by the Global Electric Vehicle Network evaluation team all refer to lead-acid batteries. Generally, the battery specifications of electric vehicles are divided into four types: 36V, 48V, 60V and 64V.
With the upgrade of simple electric bicycles, the 36V which was commonly used in the past has gradually disappeared from people's sight. Currently, 48V is the most common, accounting for over 90% of all e-bikes. users.
Detailed information
Electric vehicle battery maintenance methods:
1. Determine whether the AC power and charger input voltage are consistent.
2. Determine if the output voltage of the charger matches the rated voltage of thebattery.
3. First plug in the plug connecting the charger to the battery box, then plug in the AC power plug.
4. If the charger is used indoors, precautions should be taken to avoid humidity and vibration. It is strictly prohibited to cover it during charging and should be placed in a ventilated and heat-dissipating place.
The battery cannot be recharged at any time:
1. Lead-acid batteries are not lithium batteries and cannot be recharged at any time. The lifespan of a lead-acid battery is limited. calculated based on the number of charges and discharges. The battery is the most feared. If the battery is low, always keeping it fully charged can extend its life.
2. When charging, the charger light will first be red and then green. Once the light turns green, the floating charge should be ensured for 2 hours, which ist good for inhibiting battery sulfation.
Prevent battery overcharging
1. Overcharging the battery produces a large amount of gas and washes the plates, accelerating the loss of active materials on the plates and shortening the battery life.
2. Overcharging the battery accelerates water loss, causing the electrolyte to dry out and the battery temperature to increase, causing thermal runaway, plate expansion, and case deformation.
Prevent excessive battery discharge:
1. To avoid significant current discharge, try to use your feet to help you when starting, going uphill, and driving against the wind.
2. Avoid long-term discharge and do not frequently drive with the battery completely discharged. Recharge when battery capacity decreases by 1/2.
Avoid battery loss:
The batterywhich has been left unused for a long time should be fully charged once a month. Generally, it is best to continue charging for 5 hours afterward. the red light on the charger turns green.

The mobile phone has been used for 2 years and has been recharged several times. Should I replace the battery?
I just make Thinkpad notebooks. There are several ways to verify the authenticity of the battery. Let me explain briefly: 1. Batteries all have SN codes. This SN code is unique and can be seen on the warranty card.
2. You can visit the official website http://think.lenovo.com.cn.
3. You can also verify authenticity by dialing 8009908888 from a landline.
Additionally, you can click the battery icon in the lower right corner of the system taskbar to view moreDetailed battery information, such as battery brand, production activation date, use date, battery charge and discharge times. , etc., this software is unique to ThinkPad laptops and allows users to intuitively see the battery status.
Let's just say this. If you don't understand anything, you can leave me a message, I hope I can help you~
Under normal circumstances, the lifespan of a mobile phone lithium battery is approximately 500 charge and discharge cycles. One cycle means that the battery power goes from 100% to 0. If the battery is used at 20% of its power and then recharged each day, this equates to 0.8 cycles per day. In two years, the battery life is almost the same. even.
Although the battery can still be used after 500 charge and discharge cycles, the user estimates that the puissance is visibly insufficient. In the past, it was enough to recharge it once a day, but now you have to recharge it two or even three times a day. Although users can currently think of many ways to extend battery life, such as downloading battery optimization software or even finding ways to restore battery power. Unfortunately, the lifespan of lithium-ion polymer batteries is irreversible and there is currently no technical way to repair long-used cell phone batteries.
So when your cell phone battery is obviously not enough, the best way is to replace the battery. It is relatively cheap to replace domestic cell phone batteries. For example, the Xiaomi Mi 6, launched two years ago, the official price of the original battery is 59 yuan,plus the labor cost of 40 yuan, the total can be 59 yuan. be replaced for 99 yuan.
Considering that the performance of previous generation flagship phones like Xiaomi Mi 6 is still quite adequate, it is still very cost-effective to spend 99 yuan to "rebirth " battery. .
However, if it is an Apple mobile phone, the cost of battery replacement is relatively high. Take the example of the iPhone 7 of the last two years. Apple's official after-sales price for replacing the original battery is 359 yuan. For iPhone X level and later models, the battery price can reach 513 yuan. . Although Apple officially has no labor charges for battery replacement, the battery price of more than 300 yuan is still quite astonishing.
Thus, some Apple mobile phone users will attemptnow have to replace the battery with a third-party brand. Nowadays, the batteries produced by some old battery manufacturers are no worse than Apple's original batteries, and the prices are much cheaper. You can usually buy a good third-party battery for around 100 yuan. If the user has strong practical skills, he can follow the instructional videos on the Internet to replace the Apple mobile phone battery by himself.
However, it should be noted that most Apple mobile phone batteries are stuck in the fuselage with double-sided tape. Under normal circumstances, they should be heated with it. an air gun before you can successfully remove them. If you use tweezers or other hard objects to forcefully remove the battery, the battery shell may be punctured, causing an internal short circuit or even spontaneous combustion.tanned. Therefore, if you are not absolutely sure, it is best not to try to replace the battery yourself. You can choose to buy a third-party battery and go to a repair shop in the electronics market to replace the battery, and the price is. not very high.
My cell phone is a 6S and the battery was replaced around May last year. The battery status at that time was half a day. 100% battery in the morning, 40% left around ten o'clock. I don't dare to browse Weibo when I go out, and I can't watch Sister ** on TikTok. A power bank is essential. After I couldn't take it anymore, I went to Taobao Fujishima to replace the battery myself.
It is certain that Taobao's battery is not as good as the original one. Basically, battery performance will start to decline after about five months. And100% power in the morning can last up to about 3 p.m. Now, for almost a year, battery life has been significantly reduced, with at least two charges per day...
Cell phone batteries on the market are now mainly divided into lithium-ion batteriesand lithium-ion polymer batteries. The original batteries are generally lithium-ion batteries, while Taobao batteries are basically lithium polymer batteries, and their performance is necessarily lower than that of the original batteries.
Since its birth, the lifespan of a lithium battery has been determined - about 500 charging cycles. Charge cycle here refers to charging the battery from 0% to 100% and then using it from 100% to 0%. Once the number of charge cycles is exceeded, battery life will drop. In che moment, it's time for everyone to replace their cell phone or replace their battery.
1. Lithium batteries are most afraid of high temperatures. Try to avoid charging them when playing with them. There are many reports of injuries from explosions on the Internet.
2. And the charger cannot be used universally. Different chargers cannot be used universally. Mixing rechargeable batteries will accelerate the aging of the battery.
3. The optimal condition of the lithium battery is 20-80%. for a long time and do not charge when the battery is too low;
4. Try not to replace the cell phone battery by yourself. The replacement process will inevitably cause the battery to short circuit or leak. which is very dangerous. In mild cases it will burn the operator's hands and in severe casess, it will explode. Make sure you pay attention to safety.
1. Scud, I vaguely remember that when I changed the flip phone battery ten years ago, I had Scud, and I'm definitely pretty skilled;

Generally, the purchase price of batteries is about 100-1500. Don't choose those that are too strong. cheap, because the quality is usually unreliable, and don't choose one that is too expensive. This is really not necessary because a cell phone that has been used for several years may not be worth hundreds of dollars.
I wonder if anyone has any good battery brands to recommend? Please leave your valuable opinions in the comment box!
First of all, let's not talk nonsense. If you want to continue using this phone, you must replace the battery, because you cannot keep powerelectrical ation on your body.
Current technology has increased the number of charging times of lithium batteries up to 500 to 600 times, which means it takes about twice to charge one new mobile phone from 100% to 80% For about a year, it is estimated that most of us will rush once a day. Perfectly meets daily needs.
Let's talk about my two cell phones. The first one was used for a year and a half and the battery was no longer durable, it could only last more than half a day, so I changed. the battery myself. The result The battery was replaced, but the screen was broken. I spent over 400 to buy a screen myself and replaced it.
The second one was just replaced three months ago, and this one has been in use for two years. After replacing the battery, the phone came back to full health. We can say that waking time is comparable to that of the new official phone. You can play games for more than 4 hours. My cell phone was purchased in 2017.
The most important thing is that battery replacement has a lot to do with the cell phone. If your cell phone costs a thousand yuan and you've been using it for two years, it's not worth spending another 100. yuan to buy a replacement battery, so we need to do a gender-price comparison.
If you are not skilled enough to change the battery, go to a mobile phone store to change it. It's better to buy the battery yourself, because the batteries from the mobile phone store are really not good.
No matter how many times you charge it, the key is to check the phone's battery status to see if it is normal. What type of cell phone health is normal? We feel it :
The iPhone X has been used for more than two years and the current battery status is around 86%. I will not replace the battery of this phone because it does not meet the standards given by the iPhone (the battery capacity is 80%).
When the battery is 80%, the battery health cannot meet our requirements for mobile phones. We saw from the official website that according to the iPhone battery life regulations, about 80% of the battery cycles are about 500 times. Currently the battery needs to be replaced.
Actually, when we use the battery, if the battery power is more than 80%, we may not be so worried. In fact, in 2 years, depending on the battery under normal conditions, health may be poor. have It's completely below 80%.
Why do we value 80% so much? the reason is simple. In 80% ofcase, on the one hand, the storage life of the battery will decrease; on the other hand, because the mobile phone will implement performance mode, like the iPhone, there may be a lag, so-called frequency reduction.
If you feel that your phone is stuck or has no battery, you can consider upgrading your phone.
1 It depends on the type of mobile phone you have and whether the battery consumption time is the same as before. I have an iPhone 6s and haven't replaced the battery in 4 years. I gradually noticed that the battery was becoming less and less durable. Sometimes I don't do anything after going to bed at night and the battery is reduced. by 10% the next day.
If you have an Apple phone, you can check the maximum capacity of the battery once it is fully charged by following the steps below:
1. Open the parameters of thephone
2. Select Battery
3. Select Battery Status
Then check the maximum capacity of normal batteries. I just replaced a battery this year, and this. the battery which has been used for 4 years still has 80% charge, this is equivalent to a full charge, although it shows 100%, but the actual power is only 80%. If it is below 85%, it is recommended to replace the battery.
The lifespan of most lithium batteries is around 500 cycles, including iPhone batteries. After about 500 times, the battery performance will decrease and the battery capacity will decrease very obviously. If you want to maintain battery life and experience, it is more appropriate to replace the battery.
If you charge a lot, the battery may have worn out more than 20% in less than 2 years, leaving less than 80%.
Unless you wishIf you want to change your mobile phone, I suggest that it is better to replace the battery, because insufficient battery capacity will seriously affect the battery life. Additionally, some batteries will expand, and after expanding, they may even press on components such as displays, causing extrusion issues. Of course, if it is an iPhone or other models, it will leave some space in the battery compartment for the battery to expand. This is why a third party can install a larger battery, because the larger battery takes up the reserved space.
It must be said that the battery is the most easily lost hardware in mobile phones, and its loss is irreversible, no matter how you flash the phone or how advanced the algorithm is , battery loss is. a loss.
Apple users can check your battery consumptionie through battery status information ~
Many brands offer after-sales service for battery replacement. I myself went to Meizu and Huawei for after-sales replacement. batteries are not expensive. The cheapest model costs a few dozen yuan, while the most expensive model costs more than a hundred yuan. This already includes the labor cost of the master.
So, if you have an Android phone and you do not want to change your phone, then you can definitely go to an after-sales point to change the battery. The price is not expensive and you can restore. battery life, which is great.
If you have an iPhone, there's nothing you can do. The cheapest official after-sales service costs more than 300, and the most expensive costs more than 500.
Of course, you can also find third parties to replace it, notament some e-commerce platforms that offer battery replacement services! The price is around 100-200, which is quite reasonable.
The frequency of battery replacement is determined by how often the phone is used and charged. Generally speaking, the charging and discharging frequency of mobile phone batteries is 300-500 times, which means that a new mobile phone battery needs to be replaced within one or two years. When should the battery be replaced? It depends on battery life. When we query the battery details, we can usually see that the battery life is a percentage, which represents the loss of the battery. Generally speaking, the actual capacity and design capacity of the iPhone can be queried through software. Battery life is the actual capacity value/rated capacity, and the resulting percentage is the current battery life. When the battery charge cycle reaches about 350-500 times, the maximum battery capacity drops below 80%, which is the standard when we need to replace the battery. Apple officially recommends that if the battery life is below 80%, we should replace the battery.
For other brand mobile phones, you can check the battery status by downloading detection software.
When the battery life is less than 80 %, the battery can still be used, but the endurance will be greatly reduced, unexpected shutdown may occur when the battery is low. So the battery life is less than 80%, which indicates that we need to replace the battery.
The mobile phone has been used for 2 years. The need to replace the battery dependsd battery performance. Since ordinary users do not have professional equipment, they can evaluate it based on battery life.
Affected by the underclocking incident, Apple added options for battery health. According to official Apple data, the battery should be replaced when its health drops below 80%.
Therefore, by checking the battery health, you can assess whether your iPhone battery needs to be replaced. My iPhone 8 Plus battery health is still at 85%, battery life is still good, and there is no need to replace the battery at this time.
Since most Android phones do not have the function of test the condition of the battery, you can use the battery life to determine if the batteryie must be replaced. Under normal circumstances, the battery life of an Android phone is around 24 hours, and for heavy users, it is only around 15 hours.
In the system power options, if you find that the battery life is more than 20 hours, there is almost no need to replace the battery. battery. For my Android phone, the battery health is within the normal range.
Of course, the need to replace the cell phone battery can also be assessed based on the usual battery life. If you feel that your phone's battery life is significantly shorter or that the battery charge is diminishing too quickly during normal use, this is evidence that the battery needs to be replaced.
If the subject's cell phone has been used for two years, the battery is indeednot very good. After two years, it has been charged almost once a day, and it has been charged almost 600 times. battery life has been practically exhausted. Second, there is still use. During the process, charging and using mobile phones, etc., still cause a lot of battery loss.
So, battery replacement depends on the type of mobile phone you are using. If you are using Apple mobile phone or domestic flagship mobile phone model such as Huawei, Xiaomi, OPPO, Vivo. , etc., then you can consider replacing the battery. For some sub-headlight models, it's not worth it. After all, the price of mobile phones is so high, and battery replacement is also a cost. They have a common problem. They will become sluggish after prolonged use, and after two years they will still be stuck. There are very few cell phonesable to function properly.
After checking, the official battery replacement price of the above brands is roughly around 80-150 yuan. Apple may be slightly more expensive. You can check the price on the official website of each brand, or you can do so. choose some third-party websites (such as Suning.com, etc.) that also offer battery replacement services!
The subject can refer to the suggestions below and consider them holistically!
If your cell phone battery has been used for two years and you want to continue using this phone, I recommend replacing the battery.
Because during these two years, as the mobile phone battery continues to be charged and discharged, the battery life will become shorter and shorter, and the energy storage will not will not correspond to the reference value. The capacityBattery power will decrease and consume power more and more quickly. At this point, it is recommended to replace the battery with a new one. to improve the situation of excessive energy consumption.
