I own a 2009 FEH with 141k miles (bought it new) - excellent vehicle and very dependable, but would like to keep it longer and get to at least 250k miles.
I have been religious about maintenance, but would like to take it to the next level and start watching the codes and battery SoC level.

I'm going to purchase a Veepeak BLE+ OBD2 scanner to plug into the OBD port. ($39.99 on Amazon)

I have an iPhone and would like to try the Car Scanner ELM OBD2 app or the OBD Fusion app to check SoC level. Will either or both of these apps check the SoC level? If not, what app will read out SoC?

Thanks in advance.

 

Get Forscan, that will show more than SoC.

 

the SOC runs between 40-53% with the vehicle designed to hold around 53%.

 

So this used battery I just put in runs at 54% and will hold it overnight, but I let it sit for a week and it dropped to 17%, voltage was steady though and it still started, is this ok or should I try and find another battery.

 

You are talking about the HVTB correct?

 

That's an end of life battery IMO. My '07 battery is in that condition now.

 

Yes, the high voltage one
