Previous articleOfficial channels of purchase: where Xiaomi sells original batteries
The most reliable way to buy an original battery is to contact Xiaomi’s official partners, but there are some nuances: the company does not always supply batteries for older models directly.
- 🛒 Official Mi Store (online or offline) - if the battery is still available. Check the Accessories section for the Redmi Note 7 site mi.com/ru.
- 🔧 Authorized service centers - often have original spare parts stock.
- 🌍 Global platforms such as AliExpress (but only official sellers marked "Xiaomi Authorized.
Important: even in official stores, you can sometimes get fakes. Always check the serial number of the battery through Xiaomi service (for more information in the section on authentication). If the battery is sold without packaging or with a damaged hologram, this is a reason to be wary.
⚠️ Note: Official batteries for Redmi Note 7 have articular MB-J10 (4000 mAh) or MB-J11 (Any other designation is a sign of forgery.
Marketplaces: how not to run into a fake on AliExpress, Wildberries and Ozon
Buying on marketplaces is always a lottery, but there are ways to minimize the risks.
| The playground | Pluses | Cons | How to Choose a Reliable Seller |
|---|---|---|---|
| AliExpress | Low prices, wide range | Lots of fakes, long delivery | Look for sellers with a rating of ≥98%, reviews ≥1000 and a mark “Top Brand” |
| Wildberries | Quick delivery, possibility of return | Prices are higher than on AliExpress | Check the packaging photos and certificates in the product description |
| Ozon | There are often official suppliers. | High chance of getting caught by the dealers | Give preference to sellers marked "Ozon Premium" |
The rule is that you should never buy a battery without a photo pack with a hologram.
- 📦 Packaging with the Mi logo and QR-code (can be checked through the Mi Home app).
- 🔍 Hologram on a battery with a changing pattern when tilted.
- 📊 Receptacle marking 4000mAh/15.4Wh tension 3.85V.
Critical moment: AliExpress under the guise of original often sell batteries with a capacity of 3,500-3800 mAh instead of the declared 4000 mAh. Such batteries will last 1.5-2 times less. Always require the seller a photo of the real product (not stock pictures!) and a video with a test capacity.
💡
Before you buy it, write to the seller, "Send a photo of the battery with the hologram and a video of the multimeter showing the capacity." Honest sellers always do this, scammers ignore or refuse.
Local service centers and workshops: pros and pitfalls
If you don't want to wait for delivery or risk with marketplaces, you can go to local service centers.
- Authorized Xiaomi services are guaranteed to supply the original battery, but the price will be higher than the market by 30-50%.
- Informal workshops - can offer cheaper, but the risk of running into a fake or used battery is higher.
How to choose a reliable workshop:
Ask what type of battery will be installed (original or analogue)
Ask to show the packaging before installation
Check if you have a job guarantee and spare parts
Check the reviews about the workshop on Yandex.Maps or 2GIS-->
Average prices for battery replacement in services (2026):
- 🔋 Original battery + Replacement: 2500-3500 ₽

How to check the originality of the battery after purchase

- External inspection: The hologram should change color when tilted. The battery labels are clear, without blurred symbols. Contacts are smooth, without soldering marks.
Mi Authenticity

Capacity test:
Use applications like AccuBattery or CPU-Z to test the actual capacity. The original battery should be 3800-4200 mAh (adjusted for wear and tear).
If the battery fails to pass the check, immediately contact the seller with a request for a return. Under the law on consumer protection, you can return the goods within 14 days without explaining the reasons (if the packaging is not broken).
What if the seller refuses to accept the counterfeit?
Alternatives to the original battery: when it makes sense to buy an analogue
The original battery for the Redmi Note 7 is expensive, and it's not always available, and in some cases it's wiser to look at quality analogues.
| Brand | Capacity | Pluses | Cons |
|---|---|---|---|
| ZMI (a subsidiary of Xiaomi) | 4000 mAh | Quality is almost like the original, affordable price | There are fake brand names. |
| Baseus | 4200 mAh | Increased capacity, good reviews | Maybe a little bit out of the hull. |
| Remax | 4000 mAh | Low price, widely used | The service life is less than the original |
If you decide to take an analog, pay attention to:
- 🔌 Compatible with charge controller – cheap batteries may not display charge percentage correctly.
- 🔥 Overheating protection – original batteries have built-in fuses.
- ⚡ Charging speed – some analogues do not support fast charging Quick Charge 4.0.
💡
If your Redmi Note 7 often overheats or discharges quickly even after you have replaced the battery, the problem may be the power controller, which requires a comprehensive diagnostic at the service center.
Common mistakes when buying and replacing a battery
Even experienced users sometimes make mistakes that lead to a quick battery failure or damage to the smartphone.
- The Redmi Note 7 has two versions: m1901f7g (global version) and m1901f7h (for China). The batteries are interchangeable for them, but it is better to check with the seller.
- Ignoring calibration after replacement: After installing the new battery, you need to completely discharge and charge the smartphone 2-3 times so that the power controller correctly determines the capacity.
- Self-replacement without experience, if you open the case in a careless way, you can damage the plumes or the display, and if you've never taken out a smartphone, you'd better go to the service.
- Using a non-original charger: Cheap charges can deliver unstable voltages, which shorten battery life.
Another common mistake is to believe vendors who claim that their battery is “better than the original” and in practice, these batteries often have understated capacity or substandard cells, leading to bloating or even fire.
How long will the new battery last and how to extend its life
The life of the original Xiaomi Redmi Note 7 battery, when properly operated, is 2-3 years (or 500-800 charge cycles).
- 🔌 Avoid deep discharge (below 10%) and recharge (above 90%.
- 🌡️ Do not use your smartphone in temperatures below -10°C or higher +40°C.
- ⚡ Turn off fast charging if you don’t rush it – it speeds up battery wear.
- 📵 Keep your smartphone with a charge of 40-60% if you do not use it for a long time.
To monitor the status of the battery, use the applications:
- AccuBattery - shows real capacity and wear.
- CPU-Z displays battery information in the Battery section.
- Mi Battery Doctor is the official application from Xiaomi for charging optimization.
💡
If after replacing the battery, the smartphone began to discharge faster, check the energy consumption in the settings: Settings → Battery → Battery use. Perhaps a poor application or background processes are to blame.
