Where and how to obtain hybrid compatible scanner?

This is driving me nuts. I own three Prii, and the dealer is no help whatsoever (ie -- it's a P080A -- we can replace your battery for $5000).

I keep reading about bluetooth scanners to use in conjunction with a laptop -- all seem to be sold out everywhere, and I don't have a laptop anyhow. Is there one that will work with an android phone and app?

Is there some way short of becoming a Toyota certified mechanic to get a tool to read these damned things?

I'm so frustrated at this point with a scannner that will ONLY tell me "Battery Voltage Low", I'm thinking about parting out my 2008 Gen 2. That'd be a shame -- it's been a great car until now, but is not worth what the Stealership wants for a whole new battery.
