Yes, the controller will continue to work... It will just have poor write performance. You should look to replace the battery, though. They are still available.

And what about reading data? Poor performance also? –  gedO Sep 11 '13 at 13:15
    
Reading will be okay... You can set the controller to cache reads. THe battery is only useful to protect and buffer writes. –  ewwhite Sep 11 '13 at 13:18
    
So, I can remove cach module with battery from RAID controller and controller stil work? –  gedO Sep 11 '13 at 13:26
    
Yes. You can remove the battery, but leave the cache. –  ewwhite Sep 11 '13 at 13:27
