Oh it's(disconnecting and reconnecting the battery to trick the ECU) just what folks do at 1/4 mile race tracks to get better ET's.

A battery is a battery in my opinion.. I drive daily so cold cranking amps and how long the battery last are most important to me. However, if your into weight savings for racing then I'd go for the brands the other rennlisters listed.

1/4 mile trick? I'm embarassed not to know what that means. I'm confused- is it garbage to be replaced - I got cheaped out- or does it not matter- it fits correctly it appears to have proper loads and amps. etc.. I can't find the "vent line"- new with car.
