We just bought 2 new T-105's from a battery shop in town for $125 each, which I thought was a pretty good deal. I looked all over the internet and couldn't find a decent price. Shipping is really the deal killer. Since our old T-105's lasted 11 years, I wanted the same brand of batteries. Finally I called a local, independent battery shop and they told me they were $125 with the core exchange. Again, not in the best part of town, but they specialize in batteries and it's a very busy shop! The price made me a very happy camper, and they even carried my old ones into the shop and the new ones out to my car!
