This is a tutorial to change the battery to the Chuwi AeroBook for an official or compatible one.
In the first place, to say that this is not an official response of Chuwi to the problem raised with some batteries of this model that, after a few months of use, fall from performance even becoming almost unusable the laptop without being plugged into its charger.
Chuwi, for the moment, recommends sending the AeroBook to its after-sales department to perform the warranty repair there since the regulations in China do not allow the shipment of lithium batteries through a transport agency. I know for sure that Chuwi is trying to find a solution to this.
Having said this, we take action.
Given the drop in the battery performance of my AeroBook I tried to find an alternative solution to that offered by Chuwi, in my eagerness to find the reasons for the failure and if the battery was really the problem.
I looked for the battery providers and found a store in AlíExpress that offered both a battery equal to the official one, and a compatible one with a little more capacity.
In the end, to avoid falling back into the bug if it played on the official battery, I decided to ask for the alternative.
The purchase link is this: https://es.aliexpress.com/item/4000210393125.html?spm=a2g0s.90423126.96.36.1990e63c070KaZ6
The order arrived to me at three weeks, in a perfect packaging and very well protected.
The battery has the same connection as the official one, so you don’t have to make any adaptation.
To change it, you have to unscrew the screws that appear on the bottom cover surrounding the entire laptop, plus the two screws of the SSD cover, plus two other screws hidden under the rear rubber feet of the AeroBook. In order to reach them, it is necessary to take off, with the tip of a flat screwdriver, part of these rubber feet, without having to take them off completely.
Put the screws in a safe place and taking into account the location of each of them since there are three different models for their size. As an aid you can make a sketch on a paper with the drawing of the AeroBook and deposit the screw in the corresponding place.
Once all the screws have been removed, with the help of a plastic spike we must separate the cover, starting at the farthest part of the hinge, that is, by the corners near the touchpad and patiently and without forcing the clips of adjustment.
Once the cover is removed we will find the battery in the foreground that is fastened by 6 screws to the chassis.
We must remove the 6 screws and then with smooth movements remove the plug of electrical connection to the motherboard. I did it only with my fingers, I didn’t need any tools to disconnect it.
In order not to lose the screws, since the new battery does not need them, we must re-screw the screws in place taking into account that there is one, of greater length that also serves as a fastener to the frame of the SSD compartment.
The battery will be released and it is time to take the new one.
We must first locate the destination of the battery and once the place is found, taking advantage of the existing side tabs in the area closest to the hinge to verify that it is stable.
Next we must connect the plug to the plate gently until it reaches the bottom.
Once connected, it is time to secure the battery so that it does not move. For this we must use the adhesive tape that accompanies the battery. I cut it into two halves, using one vertically and the other horizontally on two sides, being firmly fixed.
It is time to replace the cover and put all the screws respecting where they came from.
Once the process is finished, we must turn on the AeroBook and verify that it works, although the values that the battery manager will give will not yet be true. Once it is checked that it turns on - it may do several reboots before starting Windows - we put the charger and let the load percentage reach 100%.
It would also be of interest to perform a battery calibration if we see that it does not reach 100% during charging.
