I'm happy with Eaton. I have one (managed) powering this desktop (has 2*12 batteries), and I bought another (not managed) for my router, just one 12v battery. I think it beeps when battery is bad, we'll see. The new one at the router is not managed, but I don't have a permanent computer there to manage it, anyway. -- Cheers, Carlos.
