The Dallas Real Time Clock chip on the card - that's the battery. It's supposed to hold your RAID cache in case you have a catastrophic loss of power, but in the PERC5s and 6s having the battery go ga-ga on you typically triggers alerts or (worse) errors - in modern SSD equipped machines those pesky batteries are replaced by supercaps. It's one of the first things you check for when you get a secondhand RAID card...is the battery good? Is the onboard RAM modules good? That practice wa beaten into my head when I was a data center youngun', and what I beat into the heads of the guys that I manage - saw way too many issues from the past to let the issue breeze by.
Dude, I think you are confused. First, you are attaching my name with a quote from Vogons user wirerogue who actually asked that question. Also, if you go back and look at the post, the RAID card we are talking about (AAA-133U2) does not have a Dallas on it. Most of us here know what a Dallas is and its function.
