new released products? What is the MTBF of the battery in hot climates? Can you answer that question? BTW, a battery is a consumable item, unlike a turbo which is a durable item. If you are so confident on the battery, how about us Arizona guys test it out for free for two years? Wait, you aren't a specialty Z employee or parnter? I am willing to bet if Z1 came out with this product you would not be defending it so strongly.
