ProComp/Speedmaster aluminum heads

So the yellow top optima $265 battery Fiasco.... I get it all happy install it all happy check the voltage on it not so happy LOL read the paperwork and it says it should be between 13 and 13.2..
It's 12.68... they have recommended chargers for these batteries which I don't have the recommended charger. I call optima tech line and they say try charging it and see if it holds and my 2 amp charger would be fine.. I called Summit to see if they approve all this as they're the ones who have to warranty it and I get the old codger who wants to have a standoff with me saying to just go ahead and put it in my car and let the alternator charge it? I'm like I don't want to spend this much money to burn out my alternator charging the battery I would rather have it pre-charged.. he goes on to give me all the statistics of how many he sold and blah blah blah out of his Warehouse blah blah blah. I just think to myself forget it and call back later and get someone else so I did. this kid gets on and says he'll call optima to verify call me back and never does LOL then I get the lady at night and she just notes it all so I can help them retain the sale but not be liable if the battery doesn't take a charge...

Man, you make me feel better about not being able to buy any new parts right now... Look at the aggravation it saves me!
