No unfortunately, best idea is to ride it and note how many miles you can go

The only measurable thing in this context is cell resistance which rises with age. It's not practical to measure this precisely with a multimeter and in any case, any result would only be useful if the cell manufacturer's data for resistance throughout life was available.

Even then, it would only give a range decline indication and couldn't predict low voltage cutoff occurrence which can be the practical end of useful life.
