What would it cost to replace the batteries on a 2010 Camry Hybrid? on 2010 Toyota Camry Hybrid

Any idea how long the batteries should last and what the warranty is?

8 yr 80k warranty. the batterys installed are about 3500. i would add another warranty to the car before the warranty expires. they usually last about 10 years
