I would never lease a battery like this. What happens if, at the end of your lease, the manufacturer decides no longer support your vehicle and doesn't renew your lease?
Not to worry, if you’re planning on keeping the car beyond 7.5 years, you may have an option of paying ~$15K up front and owning the battery, rather than paying ~$2K annually for the life of the car (and I’ve read the warranty says no more than 30% degradation within the warranty period). My 2012 Volt battery is still healthy and within those warranty specs after 10+ years.
Here’s a November 28, 2022, PC Magazine article about VinFast I found on the internet that says:
"Vietnam is set to make its US car debut next month when the first shipment of nearly 1,000 cars made by EV company VinFast arrive on US soil... Customers should receive their vehicles by the end of December. The current shipment contains 999 VF8 models, although VinFast also makes a VF9, which it will begin exporting in 2023... VinFast is looking to differentiate itself from more established auto brands via a unique payment model, which allows for a lower upfront cost for the vehicle, paired with a separate "battery subscription." The VF8 costs $42,200, plus $169/month for the battery. The VF9 goes for $57,500 with a battery subscription of $219/month."
It seems you have a choice, to lease the battery or buy it outright. Edmunds.com reports, "Starting price depends on whether you lease the battery ($42,200) or buy it ($57,000). At $169/month = $2,028 annually for the battery lease.
Get ready to see an unfamiliar logo on the highway, as a new electric car brand with a unique battery subscription model debuts on US streets next month.
