Re: Hmm. Strange symptoms.. (2001 2500HD - ding ding ding)
I wish I could use those on my 05. They'd fit the GMC on the LH battery.
The clearance between the fuse/relay panel and the stock battery bolts on my 2005 is just too tight for those. I have to use a ratcheting box end wrench because I can't get a ratchet and socket in there.
I use a Ctek 7002 on my Impala over the winter. The 7002 is overkill for the job. I originally bought it for the high frequency pulse rehab function to bring back dying batteries in my flip cars. It doesn't make em new but it breathes additional life into them that a regular charger wouldn't.
