Those are the giant truck battery ones, 43.8lbs for the yellow top. Still not light by any means.
Only yellow top that actually lasts and does what it is supposed to do. 60lb. Battery is brutal.
90% of the time if someone is having optima problems they are doing something wrong somewhere. We sell maybe 1000 of them a year and see very little failure. Most of the problems come from show cars, race cars, and things that don't get maintained and properly charged.
If you have to have the 60lb yellow top to function in your car there is problems.
