My wife's Mustang started going through these top of the line batteries a couple of years ago. Sears (what a joke) could not find any problem with the car which they demanded to check after the 2nd battery died in just 6 months. She paid the local Ford Dealer $200 and they could not find any problem with the car's charging system or any other reason for the 3-month battery life. She bought a booster pack because Sears got tired of us killing their "good" batteries. I have to remove the battery terminals and charge up the battery about every 3 months. Any ideas? Thank you, MLH.

As the battery is suspect here and the charging system is checking out good with out any perceptible parasitic draw, then dump that piece of s*** Sears battery and get a good one from Interstate or Costco or even Pep Boys and let us know what happens.

I too bought a Sears Diehard about 4.5 months age. I have had it replaced 3 times, my car has had to be jumped off about 10 times. My car center can not find anything wrong with my car but the power on the battery keeps dropping after 3 days on his machines. We have now replaced it with a different brand of battery. After being on the machine for 8 days no power drop. We are now ging back to Sears to see if they will refund our money. This car does sit for several days and that is when the problem would show up. 1997 Jeep.
