Go find one on ebay or google search, and plug it in. Adaptec
batteries just snap in and sometimes have a bracket to clip them in
place.
Your performance will be awful without one since you can't safely
write cache. Also, if your card has upgradable RAM (but I've never
seen an adaptec card which could) max it out.
