Wouldn't fret too much about that. Lifetime warranty. Great! If it dies, you get a free replacement.
I only fret about OEM counterparts when critical components are at stake...MB pistons from Pep Boys? Timing chain kit from Auto Zone? Not a chance!
If I can save a few bucks on a reman starter or alternator, cool. Ever price an OEM R129 battery? I was off to Interstate for the replacement.
Next time before things get critical, try FastLane...
