BrownGhostDK, You can go to Dell.com and search for this part number 312-0448. It's the same kit for the Perc 5.6. and h700.  To replace it you would need to power down the server and remove the power cord, then hold the power button to drain the flea power. After that then simply remove and replace the battery. Power back up normally. The configuration is stored within the controller and wont be lost by replacing the battery. The batteries primary role is to provide the power needed to save the cache data in case the server goes down.  Let me know if this helps..
1. where do i buy it, and what exact model battery is it.. link please if you have :) 2. How do i replace it? a guide for how to do it.Must one power down server? Or can one replace it while server is running? 3. If i replace it, do i loose my config, raid setup and other stuff, like if you take bios battery our, you loose all config.. ?? Thanks, hoping some one will help me out here, its my first time changing battery..
