I have been using Die hard batteries as replacements in my cars and boat for over 25 years with much satisfaction. When it became time to replace my auto battery it was comforting to see how highly Die hard Gold batteries are rated by Consumer reports.
LIKE SOMEONE SAID EARLIER THE DIE HARD IS VERY VERY VERY MUCH NOT WHAT IT USE TO BE. I BOUGHT A 100 MONTH BATTERY FOR MY SPOUSE SUV AND THIS WILL BE THE 3RD TIME I HAD TO TAKE IT BACK, THE SUV HAD BE IN THE GARAGE FOR CLOSE TO A WEEK, THIS TIME AND WHEN SHE TRIED TO START IT, THE BATTERY WAS TO WEAK TO START. GOOD THING WE HAD A EXTRA CAR IN THE DRIVEWAY,OR HER DAY WOULD HAVE BEEN RUIN. I WAS TO FAR AWAY. IT WILL LAST FOR A LITTLE WHILE BUT IN THE LONG RUN IT "WILL" GET YOU.
