Decided to replace battery in my 99 9.3 because engine cranking was slowing down noticeably. Removed Neg. clamp, then removed Pos. clamp, then removed battery. Put new one in. Attached Pos. clamp, then Neg. clamp. Started car, set time & date in SID. Cranks very good now and no other anomolies were present. Did not even loose preset radio stations.
