As noted, no reason to condemn a battery for an electrical system fault. I have never had a conventional moto battery last even a third as long as the Shorai has in my Commando (with Alton E start). The only reason I don't put a lithium in my car when I need a new battery is the cost. One for my car is around 800 bucks and although I've been impressed with the long lifespan of the Shorai in my Norton, I don't believe one will last longer than 5 or 6 lead/acid batteries and, therefore, justify the price.
