For me it would't be worth it even if you doubled the range to 20 miles. I would get an escape PHEV (39mile range) or an EV if you don't take frequent long trips. I did buy a Mach-E standard range EV last year after I sold my c-max.

Remember, the guess-o-meter is based on your recent driving. If you have a lead foot, it might think that you only have eight miles of juice. Follow cr08's instructions, that will get to what you really have available.

I'd first start by getting the actual capacity of the battery currently. The estimated range is practically useless as a health indicator as a lot of factors can impact the numbers. Here's the test you need to do: 1) Fully charge the car 2) Drive it in EV mode ONLY (avoid things that can cause the ICE to start, ie: No highway driving, no cabin heat, as few active accessories as possible) 3) Drive until the plug-in charge is depleted. 4) Once the plug-in charge is used and it falls back to hybrid operation, safely stop somewhere and shut off the car. The trip summary on the left screen will list the kwh used. This is the number you need. 5.5kwh is the brand new plug-in capacity from the factory. Anything above 4.0 is still in good territory.
