2025 New 25.2V Battery for Xiaomi Mijia G9 and G10: Everything You Need to Know

A cordless vacuum is only as useful as its battery life. Many users notice that their Xiaomi Mijia G9 or G10 loses power over time or drains much faster than when new. Luckily, there is a reliable and affordable solution: the new 25.2V 12,000mAh rechargeable lithium-ion battery (2025 version), designed specifically for these models. In this post, we’ll go over the advantages, specifications, user experiences, and practical tips to give your vacuum cleaner a second life.

Why choose this battery?

Original vacuum batteries usually have a capacity of 3,000–5,000mAh. That may sound decent, but in practice it means around 30 minutes of cleaning on standard mode and far less on turbo. The new 25.2V 12,000mAh battery, available on AliExpress, more than doubles the capacity, giving you significantly longer cleaning time without recharging.

The price is very attractive: €51.56 including VAT. And the best part: no extra costs such as customs fees or administrative charges. In the past, AliExpress orders could come with surprise fees upon delivery. Now, everything is handled upfront, so you only pay what you see at checkout.

Key Specifications

• Model: DGDXT-7S1P-001
• Capacity: 6,000mAh / 8,000mAh / 12,000mAh
• Voltage: 25.2V
• Compatibility: Xiaomi Mijia G9, G10, and similar cordless models
• Origin: China

The AliExpress product page notes that the battery should be fully charged and discharged 2–3 times to reach optimal performance. After this initial conditioning, the battery life becomes much more consistent. This is a standard procedure for lithium-ion batteries.

User Experiences

Customers who have purchased this battery say their vacuum feels brand new again. The extended runtime and easy installation are the most praised features. While the original battery typically weakens after a year or two, this replacement brings back the powerful performance. Buyers also point out the excellent value for money. On unknown websites or from dropshippers, you often pay more than double, and returns are rarely free. Through AliExpress, you avoid these issues and can usually return at no cost.

Installment Payment Option

You can also pay in 3 installments of €17.19, with no interest. This makes it easier for anyone to upgrade their vacuum without a large upfront payment.

Installation Tips

Replacing the battery is fairly straightforward, but it’s important to be careful. Make sure you order the correct version, and if in doubt, have a professional handle the installation. Incorrect installation could damage your vacuum.
