Bad idea IMO.

The battery it comes with will probably last 15 years.  

By that time yuou probably won't even have the motherboard anymore.  

If you do still have the motherboard, good luck finding the battery you bought for it 15 years ago.  

If you do find it, the shelf life of a battery does not last that long and you should probably just buy a new one.

Funny you say that,  my MSI motherboards BIOS battery died after 3 years. 

Usually only have that problem with Gigabyte Boards.
