Both svck. make sure you have good grounds! Make sure you do big 3 and then get a Duracell agm batt, or deka agm, or Juicebox agm or energizer agm batt... Nice batts for good price

go get a duracell agm from sams club for about $140 and you'll never run an optima again. optima HAS changed, their batteries are made at the exact same low quality factory as every other battery on the market, but they use their name to mark up the price.

Optima is trash.

Yeah, Duracell batteries as mentioned would be a good choice.
