What is the Honda Clarity battery degradation rate?

I have a Honda Clarity and the battery seems to be draining quicker than I expected. Is this normal?

The
Honda Clarity
battery degradation rate isn’t specified, but Honda considers normal degradation to be up to 33% over the 8-year/100,000-mile battery warranty period.
On average, EV batteries degrade at a rate of around 2.3% of maximum capacity per year, which means that Honda’s degradation rate is higher than the average. That said, battery degradation partially depends on your driving and charging habits. Drivers who fast-charge their cars often may see more rapid declines.
Honda offers a warranty on the battery for 100,000 miles or 8 years, whichever comes first. You may also have a
Honda extended warranty
. If you find your battery is degrading faster than it should, schedule an appointment to have your Honda looked at. A new battery is costly, so you’ll want to have it replaced under warranty if it’s faulty.
