Can I reassemble the battery after I inspect my trackpad?

My trackpad isn't clicking (making clicking noises) and i thought maybe i can inspect it to see if something is stuck in between or the screws are loose. Now IF i do take the battery out (which is glued in) to access the trackpad will I be able to reuse, reassemble the battery again or would I need to buy a whole new battery? Also what would happen if i am very good at taking out the battery without any bending at all what so ever? Any help would be greatly appreciated.
