Drain on battery

[ebatters]

My 05 H3 battery dies within 5 days of no driving. New batteries twice now. I have no evidence but suspect the Viper alarm/ remote start that it came with. Any suggestions on how to trace?
Thanks.

Rip it out? Aftermarket systems are common to cause issues. But I'm not good with electric troubleshooting

Pull the fuse the alarm is on and see if the vampire goes away.

That's entirely logical and well though out. Much better reply, but less fun, than mine,.

Onstar module was also known to drain battery if onstar is inactive on early models.
