Measuring 10″ by 6-7/8″ by 7-13/16″, this battery weighs 43.5 lbs and boasts dual SAE and GM posts. If you need different terminal types, make sure to check out the rest of Optima’s YellowTop lineup.
Along with a polypropylene case like the RedTop 35, the YellowTop D34/78 has a reserve capacity of 120 minutes (versus 90 on the RedTop 35). This battery also claims to be 15 times more resistant to vibration for enhanced durability.
