I did not check for a parasitic draw, however since starting the car today it had 12.84V running and 12.47V about three hours after it was shut-off and 12.47V 7 hours after it was shut off. I won't be starting the car for a few day, but I'll check it for sure the next time I do. I will get you the retailers info when I go through my recipts this evening. I don't blame anyone for being skeptical, and I'm glad I didn't blow my top or more than likely I would have eaten the cost on the origonal one and the cost on another battery. I just hate having the feeling of needing to fight with people regarding a return or exchange whether it is batteries or other goods. I appreciate your concern on the issue, its nice to know people stand behind their brand.

 

djs383, the voltage of your battery with the engine running is the output of your alternator and should be roughly 13.7-14.7 volts. The 12.84 volts you mentioned sounds low. Are you running an underdrive pulley?
