For years I swore by Odyssey.
Not anymore. Bought 2 for the Duramax in October 2021 that were replaced under warranty this past January. Just over 2 years of service.
Had another 2 in a sports car, neither of which lasted 3 years. The first was replaced under warranty during COVID ... after a months-long wait for it to arrive. When the replacement died, again well before 3 years, no warranty coverage. That car no longer has an Odyssey in it.
Two Odyssey batteries for a Duramax are now priced at near $900 including shipping and Cali tax!
No more Odyssey for me. Damn shame too. I had a set of Platinum (?) from Sears that were rebranded Odysseys that lasted me almost 10 years in that same Duramax. THOSE were batteries.
