PiP battery heath check

I'm looking at a second hand 2013 PiP, how can I check the traction battery health? Does the Dr Prius app work with the 4.4kwh Li-Ion battery?

Anything else I should particularly look for? Cheers!

 

Thanks for the reply! She is a 2013, with 95k miles.

Did very regular 13k miles a year till march 2020 Then just 2000 since, so she has been sat for some months.

I've asked the dealer to charge it fully for a test drive tomorrow, will check the EV range as you've suggested.
I have found Toyota UK do a HV battery check for £45 which I might see if I can get done. (It seems that test looks at: Internal Resistance; Internal Voltage; Variation Check; Battery Temperature; Fuel Consumption; Battery cooling system)

I found she had a 12v battery voltage of 11.7V initially.

And the washer fluid dipstick was dry and gunky.

Are these likely to cause issues? I can negotiate to replace the washer pump and 12v battery if long term damage is likely from being sat for months.

Cheers!
