Adaptec Zero-Maintenance Cache Protection Explained
 

If you remember, back in your Tyco radio control car days going through 30 or 40 AA batteries a day was a pretty easy task. Back then no one really worried about what was going on with the batteries, so it was common to just toss them in the trash and open a new pack. Even then batteries were expensive; that 75 Dollar RC car was eating 30 Dollars worth of batteries a day. Who knows how much damage my buddies and I caused the Earth in just one summer. Fast forward to today and we now realize that batteries are not meant to be buried in the ground with our plastic water bottles and used motor oil. Battery disposal is a big concern and it costs big money when you are talking about server rooms filled with storage controllers every 1.75 inches of server rack height.
