My old Beuchat Aladin Pro was purchased in 1989, and is on its 4th battery. I have always changed the battery myself. I bought the battery kit (about $30), which included a new cap and o-ring, and the change was pretty straight forward. Since I have gotten at least 400 dives on a battery, it has seen some use, and although for the past 7 or 8 years it has been a loaner and backup to my backup computer, it has never missed a beat. But, $85 for a battery change on a computer that is probably not worth that much sounds insane.
