In my car (2021 Mach E AWD with standard battery), the battery state of health the first time I checked it was around 94% at around 48,000 kilometers. I’m not sure how accurate the car’s data is because it seemed to drop a percentage or so immediately after a couple of OTA updates. It sat at around 92% until between 80,000 km and 113,000 km, but now it’s says 92.5% at 120,000 km. Again, I’m not entirely confident at how accurate the car’s information is, but my range is still about the same as when it was brand new. I think I’m past any danger of manufacturing defects, so I don’t have any reason to suspect that the battery won’t easily last a couple hundred of thousand kilometers more.
I replaced the battery in my '16 F150 last year - I'd say it had a good run. Went with another OE battery since the original lasted so long.
Even in the colder weather now, I'd be getting 400+ km on a full charge in my BEV (Mustang Mach e). But I only charge once a week (Fri night), to 80% to help with battery life; costs about $3 per week to get an extra 200-300km.
Have a Chevy Volt. The battery is only good for 22-40 miles depending on outside temp. It gets plugged in at night and costs $14-18 a month. For the past 3 years we have used less then 25 gallons of gas.
Not many cons. The car is much better on electricity than when the gas motor has to kick in. Much quieter and has a bit more throttle response so I don't like it when the battery runs out.
Always read your manual/mfr suggestions for battery charging and longevity.
For Li-ion you generally should charge no more than 80% (some mfg hide 10% via software like Ford, so you charge to 90%). Also, limit fee cycling these types too, regularly you should DC to about 50% max. Occasionally deep cycling and full charging is fine. Should limit DCFC also.
We've been driving two EVs, a 2012 Leaf since Dec2011 and a 2017 Bolt since Sept 2017.
In the Bolt we lose about 40% range at -20 and lower. Bu the range is so good to begin with its not an issue.
A friend of mine had a 2010 ( or 2009 ) Fusion Hybrid that needed a new battery, he went to the dealer and he was quoted over $8K. He then found $3K 'aftermarket' batteries and at the end he was able to find a shop that did the whole thing for under $2.5K.
Both of mine were defective. Ford replaced them.
