When I was running two amps 2 12s eight speakers inside head unit capacitor and a built motor I use the yellow top with good success
Your alternator probably just shit the bed. Was on its last of its life then the added \"stress\" of a stereo system made it kill itself.
Anyway I know people talk a lot of crap about them but I use Optima batteries in anything that can fit them. Mainly because I have a bunch of cars and many of them sit around. Its nice to know that if the battery dies I can condition and recharge it and get back to normal and not worry.
I JUST replaced my wife's 2013 Beetle battery with a Duralast from Autozone.
I am entertaining an Optima Yellow Top this time. It's $339, for reference, and I have a feeling it will outlast/outperform the OEM.
I did and what a misnomer 'dry cell' is. Yes they are great and expensive. Both standard and 'drycell' have liquid eletrolyte so it's weird to start talking about 'drycell'
The red top really isn't that special and optima's tech in general is more beneficial in regard to durability than current delivery.
Haven't been impressed with the quality of optima over the last 5ish years.
I usually run the Duralasts just because AutoZone is everywhere and I usually get it replaced twice before the warranty runs out - Phoenix is brutal on batteries.
Have two red tops in my 05 GMC. Sneaky suspicion one is bad. They were new when I got the truck six years ago.
Went to start truck after sitting five days and it was dead. Meter showed 12.1 and it charged in an hour which is very fast. Truck would turn over but not run. Checked charge again, primary at 12.4 and secondary at 12.7. Swapped places and truck starts, runs, all accessories work now.
