Ok, my battery is a group 24 F Die hard Gold battery which has had a pretty long life. This is the first year the battery lost its charge while garaged during a very cold Upstate NY winter. I have found a really great deal from Pep Boys for a Bosch AGM battery, however, I am thinking, if Die Hard has been such a good battery, why not buy another one. The Die hard is not a AGM. Also, I can get a really good deal on a Interstate battery, also not a AGM. I will not be considering an Optima battery, too much money for me. So which one would you choose?
