I need to measure the discharge from a 3V Lithium 'coin' cell,
supplying current to some static ram and low power support circuitry.

This battery is supposed to have a 10 yr backup capability, which i
need to confirm, but I imagine the I to be in the very low uA to nA
range

Has anyone got any ideas on how to measure this reasonably accurately?
