To demonstrate another battery, it means removing the screen to get to it which 9 times out of 10 break on removal.

No receipt exists for the battery repair, just a card payment receipt for the screen repair.

Hi all. I run a business that repairs tablet devices. A customer came to me to have a screen repaired which I repaired with a 3 month warranty. The customer returned to show his screen was lifting up. This was due to his battery swelling inside the device, not because of the work I'd done . I replaced the screen again as I broke it when I tried to push it back into place over the swollen battery, so then I also replaced the battery as a 'good will gesture' and I didn't provide a warranty for the battery as it wasn't paid for . A month later, this battery now will not charge and I am of the opinion it's because of the inner workings failing due to the initial drop. Did I enter a contract by agreeing to replace the battery free of charge as a good will gestur or is it not my responsibility? If I replace the battery, the same thing will happen or another problem. All comments welcome. Thanks
