How to glue the battery + keyboard not lighting up properly

I wouldn’t use such a powerful glue to hold the battery or the bottom cover as it’s too powerful! Besides it doesn’t do well on uneven surfaces or some plastics like what is used in the battery.

The thin adhesive sheets many alternative battery makers use often don’t work as needed and not having a spotlessly clean surface doesn’t help either.

Take the battery out and clean any remaining bumps of adhesive that’s still remaining where the battery sits using cotton swabs (Q-Tips). Carefully peel off the thin glue sheet and again cleaning all the adhesive off. Then instead I use the larger 3M quick release pulls placing two per cell set equally.
