Just curious, for I struck out with google:

Who makes the batteries?

What / where is the MEGABOOST web site?

Is a copy of the warranty available online?

I wonder if they're a loss leader for Cycle Gear, to get us into the store? It's apparent that every one of them will need replacement at 5 or so years. A traditional lead acid battery for our bikes usually costs around $65. Interesting find. Love to know more.
