It use to be that phone batteries were user replaceable. The current trend is to seal the phone so that you have to basically disassemble it to get to the battery. Some people are willing and able to get the special tools and do the research to replace sealed batteries themselves, but most have to take the phone to a repair shop.

If yours doesn't have a simple battery door, then it's a sealed battery. If you are unsure, let us know which make and model phone you have, and we can let you know.
