List price on a Gen2 battery from any Toyota dealership is $1950 + $1500 core charge. They are still available, though Toyota's supply chain is very inconsistent right now.
Gen2 batteries in Phoenix last an average of 160K miles.
55K low and 386K mile high outliers (386K miles was a cab application).
Gen2 batteries in Texas last an average of 180K miles.
Gen2 batteries in extreme northern U.S. climates average > 200K miles.
STD is about ±30K miles
Gen3 batteries (all Toyota 6 cell module based hybrid batteries that are NOT 04-09 Prius) last notably less mileage and commonly have widespread damage to the majority of the pack that cannot be reconditioned to an ethically usable level.
