Don't worry about breaking +anything. As long as the material of your tools is plastic, you won't damage +anything. This is by far the most tedious step of the process (if you don't +have the picks). There is a little bit of adhesive behind the lid, so once you +get the halfs to seperate you might have to widdgle a little. + +![screws out](/media/content/sony-wf1000xm3-battery/03_screws_out.jpg){class="sm left"} +![lift top](/media/content/sony-wf1000xm3-battery/04_lift_top.jpg){class="sm right"} +With the phillips head remove the two screws that secure the visible part in +place and then carefully lift it out, flip it over.

It +is also glued in; be careful not to pull out the contact points as well. If +possible try to preserve the glue, it will come in handy when securing the new +battery in place. I also scraped off what was stuck to the old battery and +pushed it back into the housing. + +![battery in](/media/content/sony-wf1000xm3-battery/06_battery_in.jpg){class="sm right"} +Before putting in the new battery make sure to check the writing on it or use +the shape as a reference to figure out which side is the negative pole. Put +that side down, touching to the contacts. +The replacement batteries I got where a different brand and had all the +labeling on the plus pole. While the original VARTA branded batteries had it +exactly reversed. On my first attempt I didn't pay attention and put them in +the wrong way around. + +![battery comparison](/media/content/sony-wf1000xm3-battery/battery_comparison.jpg) -- cgit 1.4.1
