cant really say my battery took a dump on me, but it would go dead after 30 minutes of the headlights being on... it was a walmart special everstart, and it was about 2-3" shorter in length, it looked like a honda battery or something. it let me down when i was camping, i didnt close my hatch all the way and my dome lights were on all night, every other car i had it would of started in the morning, but not this one, it was beyond dead =/ so i went and bought a vatozone duralast gold 800cca/1000ca 105 reserve battery, starts good and holds between 12.7-12.8 when its off, and 13.8 when running and warm, mid 14's on a cold morning.
