yeah, true that. thing is, my car is drive only on weekends and it's been fine for the entire time i've had it (2 months since i bought it) but 2 weeks ago it started to startup quite roughly. and on driving at night, i thought my interior lighting seemed a bit dimmer than usual...not to mention when i flicked on the high beams, my entire electronics seemed to dim and it sounded like my car nearly stalled. so nek morning i went and changed the battery. may have wasted 150$ but at least now i know this battery is brand new, previous owner wasn't the best...
