My 78 chevy k20 has had its duralast gold battery since this time in 2012 so it is 7 years old. It has been getting tired over the years but now it does not really hold a charge long. I decided tonight to stop by Walmart and check out what they had for batteries. I was not going to buy one yet but when i saw they had group 78 everstart maxx battery made by east penn with a 10/19 date for $93 i couldnt pass it up. I did have to dig through the batteries to find the last one way in the back with a 10/19 date. I did see a few with 4/19 dates and most group 78 batteries had 8/19 dates. My truck calls for a group 75 battery but a group 78 is close enough it should fit fine. both the group 75 and 78 were the same price but the group 78 weighs 7lbs more, has 100 more cca, i think at least 100 more cranking amps plus it has 110 reserve capacity vs the 95 for the group 75 battery.
