I paid for a high-end DieHard Gold battery (640 CCA) and got a Continental 550 CCA battery instead, which is the cheapest possible version I could have gotten. Any information regarding exchanges is not addressed on the main website but rather hidden in a hyperlinked site which is further buried in ‘frequently asked questions’. If you are stranded with a dead battery you have little option but to get whatever they give you, a situation that is clearly exploited. I would not go with this company again, even though the person who installed it was very personable- to be fair.
