How much would you pay (or would you even?) for a hybrid battery health check?

I live in a fairly remote part of Southwestern New Mexico graced with loads of retirees (and young whippersnappers like myself) driving Gen II and III Prii. The dealership will run a diagnostic HV check for $125 (+tax?), which gives you zero actual data, instead just a pass or fail indication.

I'm proposing to start up a side hustle where I travel to the Prius owner's home or work and run a hybrid battery health check for them. I'll show up with a Bluetooth dongle and tablet, and run the car for testing for about 10 minutes. I can show graphs to the customer afterward and discuss how healthy or unhealthy the battery appears to be. This would be based off of the Delta V of each battery module as well as a separate report from Torque analyzing the internal resistance of each module as well. The report could either be printed on site or emailed to the customer. I'm a neutral party and the customer may not feel like I"m pushing them to buy a $2000 like the dealership may. All in all I'd like be in and out within 30-45 minutes.

Admins, feel free to pull this posting if it does not seem appropriate. I've learned a lot from this forum, and figured I'd test the waters here with so many Prius owners.

 

@frodoz737, totally fair questions. Nope, I am not a licensed mechanic nor do I plan to really do the repairs. I'm simply intending to do diagnostics using a combination of Hybrid Assistant and Torque Pro to give a snapshot into the health of the battery.

I've certainly entertained the idea of doing module replacement and/or rebalancing as evidenced by other threads i've started in the technical forum. No matter how simple pulling the battery and doing this work may seem, it will always seem a bit sketchy if not done by a "proper" mechanic. So for now, I'd like to settle on offering a battery diagnostic so Prius drivers are not driving blind about the health of their HV battery.

I was paranoid for a couple of years doing cross country road trips on our 10 yr old Gen2. After looking at many aspects of the batteries health, I'm not nearly as nervous as I used to be and will continue to monitor it quarterly.

 

@fotomoto , yup I live on the edge of the Gila in Silver City. Loads of artists and retirees with Prii in this neck of the woods. I've definitely been considering my drive time to get around, and assume that I'd have an upcharge based on mileage if it were say outside of a 15 mile radius of town. The real market is 4 hours away round trip in Las Cruces, and $100 would be a charge more worthy of my time. Lots to consider, but seems like a service worth offering.
