i've had a optima red top for 10 years. Replaced my factory battery within a year of buying the car. I have a Alpine 9835, which has an internal 6 channel amplifier directly connected to the battery...as well as a subwoofer amp directly connected...
Usually will have my android phone charging while playing music or something, and a Garmin gps connected (has the ecoroute/mechanic stuff)...
the car sits nearly all winter long...I try to start it a few times and roll the tires, but usually forget...many winters it sat for 3 months in 10 to 20 degree weather...
never once had to have this car jumped...never any questionable engine cranking...best battery i've ever used. I still get head light dim when putting all 4 windows up, but i've read thats more of an entire electrical system issue...not the battery...and grounding kits can fix that anyway...
