The battery is the component that powers all the other aspects of your Xiaomi Mi A2 (Model M1804D2SG). The use and charging cycle of a battery can cause it to degrade in its charging capacity and over time your phone may not hold a charge as much as it used to. If your Xiaomi Mi A2 is not turning on make sure to follow the steps outlined in this troubleshooting guide before resorting to a replacement.
If your battery is swollen, take appropriate precautions. Do not heat your phone. If needed, you can use a dropper or syringe to inject isopropyl alcohol (90+%) around the edges of the back cover to weaken the adhesive. Swollen batteries can be very dangerous, so wear eye protection and exercise due caution, or take it to a professional if you’re not sure how to proceed.
For optimal performance, calibrate your newly installed battery: Charge it to 100% and keep charging it for at least 2 more hours. Then use your device until it shuts off due to low battery. Finally, charge it uninterrupted to 100%.

I tried to remove the battery and tried to remove those strips carefully but the both broke so is there another way i could remove the battery
The link for the replacement battery is wrong, it leads to a battery for the xiaomi mi a2 lite which doesn’t fit into the mi a2 because the connector is at a different position
I just replaced the battery and just a heads up if anyone is struggling to remove the screen from the body - there was adhesive, so warm it up a little if it doesn’t lift easily. Reminded me a bit of iPhone 6s screen removal as the screen was near the same structure, cable was in different place.
