The following steps instruct you to use heat to soften the glue securing the battery. A safer alternative is to inject a solvent, such as iFixit adhesive remover, between the battery and rear case to dissolve the adhesive.

Reheat the iOpener in the microwave for 30 seconds.

Remember to be careful not to overheat the iOpener during the repair procedure. Wait at least two minutes before reheating the iOpener, and never microwave it for more than 30 seconds.

Place the heated iOpener in the center of the back of the iPad. Let it sit there for 90 seconds to soften the battery adhesive.

Move the iOpener to the right (away from the rear-facing camera), and let the iOpener sit for another 90 seconds.

Finally, move the iOpener to the right-hand edge of the iPad for 90 seconds.

The iOpener may cool significantly between sittings—if it does, reheat for another 30 seconds between each position.
