Optima red top vs factory battery

[YarisSedan]

So i noticed i was sitting in parking lot with my stereo on for only about 2 minutes and the speakers started to crackle like they were out of power. Started car up and power came back.

Put the battery on a load test and it failed. Fully charged it up and retested it and still failed so looks like my battery is shot. Strange its little over a year old. I think could be cause i have a system and the factory batterys are cheap to begin with. Looking for a good one. I like the look of the red tops but does anyone know the weight comparison. I assume they are slightly heavier than stock but im not sure how much more. Or if they make a smaller version for small cars thats comparible in weight but higher cca.
