DL180 G6, Smart Array P212, problem with cache battery

hi
i replaced battery for P212 cache with same part number 460499-001 and same spares number 462976-001 (same battery model, only manufacture date is different)
in ssa i get error:
"The cache for Smart Array P212 in Slot 1 is disabled because one or more attached batteries are not supported by the currently running firmware."
i tried to replace battery with another new one, same result. i tried to replace cache module pn 458943-002, spare 488137-001 (same model) - same result, error. as result: i can use cache only in read mode.
