“Heat gun”is too vague. So is IR thermometer. What temperature to soften adhesive? How would I know if I was buying the right things?

I’m not using a heat gun, it´s a hairdryer; on this case the hairdryer hardly exceeds the 60°C and that is enough to remove the battery. If you want to buy a heat gun you must be careful not to use more than 50 °
