Had a 8 month old $230 Interstate Battery Fail. Fully charged overnight and wouldn't test over 10 volts. Charged it again overnight with different charger just to make sure. Tested 9.4 volts. Brought it to the Interstate retailer in Fargo. First guy bench tested it and said it was still good and there must be something wrong with my car cables or starter. When I explained to the 19 year old, I have been an electrician for over 40 years and a car has never started on 9 volts, he sent me to his manager. He also stated the battery tested just a little weak and it was probably my cables, even though I could see his meter read under 10 volts. These bozos are obviously given a script to send unknowing people on a wild goose chase, when in fact their battery is clearly bad. They did honor the warranty but certainly not in an honorable way. I'm sure they use these tactics on all customers. A new, fully charged battery should hold 12.5 volts and up. 11.5 volts is a weak battery, under 10 volts is junk and won't start any car.
