Does not sound illegal to me (nor was I suggesting it was.) Read through the battery thread we have posted somewhere on it.com, perhaps i can find it myself and forward it to you. There was much speculation about what are the weights of original batteries. it's usually not listed in their handbooks and by the time we get our IT cars prepped, the original was been replaced 3 times over - so how can I prove that the current battery is same weight as the original? It's very hard to protest and/or defend against.
