I never had a problem with my battery. Im at 13k now. I've had it sitting for 2-3 days with no probems afterwards. I've checked and i have about 50 mA drainage(no alarm) and 67-70 mA drainage when the alarm is on, and i have tons of electronic aftermarket accesories which i installed myself. it is and maybe it isnt the battery.
Also to the origional question, i've disconected my battey many many times, and the oil life never reset itself. the only thing that resets is the switch for teh fog lamps, if you had it to on, it will be off when you reconnect, of and also the radio stations on my aftermarket pioneer.
just my experience.
