my p5s battery just went for good when i left the house to bad when i went to leave discount tire with absolutely no power(no parasitic drain or charging issues, battery just went bad) a few weeks ago, had a free replacement warranty so swapped it. it was a duralast gold 8 months old and i was thinking about just buying a different brand one that has more power and maybe will last longer (the new duralasts have less power in the south and are labeled with an S after the part number. i live in texas but its 26 degrees right now and the battery seems a little weak for that condition even brand new. i know johnson controls make most brands of batteries exide makes some and east penn the rest (like oriellys) which brand have you had good expereince with and feel i should go with? i have a 1300w total power after market system no other major electric draws other than factory stuff.
