Conventional batteries don't like to be dishcarged very deeply. That will shorten their life considerably. Yellow top is a "deep-cycle" battery which is designed to be allowed to discharge deeper between charge cycles. If your power profile is unmodified, I don't think this is of much concern. In my case, I added a computer system that goes into standby when the vehicle is off, and continually draws 180ma in this state. That shouldn't be too much trouble for the stock battery, but I decided to play it safe so I don't have to worry if the vehicle isn't driven for a week or so. One time, after I installed the Optima, I actually left the computer running at full power over night and it started up fine the next day (with computer still running).
