If yes, do we need to change it, how long can it last?
It has kinda of an Internal Battery but not the type that works for things like saving your documents , and secondly the grammatically correct question would be:

Does the iMac 2011 'have' an internal battery?

Yes, it does. It backs up certain system functions and settings (such as the clock). It's a "coin" type battery (2032, I believe). You shouldn't need to worry about replacing it for many, many years.

Since the op mentioned a "need to change it", I assumed he/she meant they knew it wasn't made to operate the iMac.

There is one for the motherboard, a round flat one found in watches but much bigger. You don't need to worry about it as it is likely that you will change your imac before the battery runs out of juice.

It has small battery, works like BIOS battery on mainboard to maintain clock, date information etc
