80% Capacity Year

Note: Battery degradation is non-linear; first 2 years see faster decline. Most warranties guarantee 70-80% capacity at 10 years.
Reference
Cycle Degradation = 0.00005 x sqrt(DoD) per cycle
Calendar Degradation = 0.5%/yr x Temp Factor
Temp Factor = 1 + max(0, (T-25) x 0.02)
Total Loss = Cycle Loss + Calendar Loss
