Disabling cache batteries on controllers

Hello.
It has an old scv2020 version 6.5.19. every 9 hours, the write cache error on the write controllers is disabled and requires replacing the cache battarei. I replaced it, but the error did not go away. Tell me how you can disable the battery dependency of the cache from the command line, so that the write and read cache works without requiring the presence of batteries.
Thanks.
