I replaced the battery and it worked for 1 week, the battery icon was on the screen which didn’t seem to get charged in full. After a week, the calc didn’t work anymore.

So you're saying when you try charge the calculator it doesn't charge the battery at all? Does the LED next to the charging port turn solid orange when you plug it in? Have you tried a different power source (i.e. your computer or a wall block) or a different cable?
