I am offering a used Axia phone battery, model HS394796.
My phone's screen became unreadable, so I am selling the phone's battery, because it is still good.
This battery has been removed.
You can remove yours by removing the back cover, then, unscrewing all the little black screws on the inner cover (there might be 10), then using a flat tip screwdriver to overcome the strong adhesive.
Then unsnap the battery where it is connected to the circuitboard at the lower right corner of the battery.
You have to just insert this battery and then press the small connector onto the circuitboard.
Note: I do not have the phone anymore.
