    Great Batteries, Great Company

    I have bought Voltaic batteries exclusively for my company as I use "Always On" and "pass-through" charging batteries only. These guys deliver on that. Plus, their customer service is second to none. I had an issue with one battery and they shipped me a new one before I could say "Boo". I've never seen service so good or so fast. I'll buy from no one else from now on. Congrats Voltaic!
