Isuzu Repair: 1999 Isuzu Battery, 1999 isuzu trooper, isuzu dealer

Question
Since 2001, I have had to change the battery on my 1999 Isuzu Trooper ( ~ 70k miles)three times.  After looking at the history, it's been replaced in the winter, summer, and spring.  So, I'm not convinced weather is an issue.  We probably drive the Trooper ~ 25 miles a day.  The Isuzu dealer doesn't have any suggestions or explanations.

Answer
Well Joe. A HUGE RED FLAG SHOULD BE PLACED ON A SLOW VOLTAGE DRAIN OR SHORT. Your battery has to make a complete circuit. Also have your alternator checked and have a low voltage check done as well. These rodeo's and troopers are horrible for low voltage issues. Low voltage causes high amperage. High amperage causes high heat. And you geussed it, high heat burns things up. I would definately have my starting and charging circuit looked at(VERY WELL).
