Don't think Optima is anywhere near the company they used to be. The top AGMs now seem to be X2 Power, Northstar, or Odyssey (at least in the diesel truck world). Optima's don't hold up worth a darn anymore, especially for their outrageous costs.
True ^^^^^^
Northstar makes a really strong AGM battery... Longevity with any battery is obviously based upon level of charge maintained to one hundred percent as soon after any discharge.
If I am not mistaken, based on case appearance, the X2 power is the same as Northstar. X2 power can be purchased at any batteries & bulbs/batteries plus nation wide and carries a 5yr free replacement.
