Galaxy Note Pro 12.2 Shutting Off at 25% of Battery.

I'm having a weird issue with my Note Pro 12.2 tablet shutting off  when  it gets to about 25% of the battery. It basically just crashes and shuts off cold. Then I can't  boot it up even safe mode until I plug it in. When I have it plugged in it doesn't  shut off at 25% or below. The Galaxy S4 phones had an issue with faulty batteries  that were doing the same thing, so I am thinking this might be the case. Although the issue didn't  start until after the latest kitkat  update.  The reason I think it is a hardware  problem is because of the date and time issue. Each time my tablet crashes, I have  to reset the date and time. That means the tablet is without power completely  when it crashes. I guess  the only way to tell for sure is a factory reset and I really didn't want to do  that yet. I have a lot of stuff on this tablet  that I will have to restore.
