(b) “Supercapacitors also last longer than batteries. Repeated cycles of charging and discharging degrade a battery’s chemical components. This means that after a few thousand such cycles most lithium-ion batteries are giving up the ghost. According to Mr Gonzalez, supercapacitors can keep going for 1m cycles.”

give up the ghost (vi; King James Version of the Bible (1611), Gospel of Mark, 15:37 [qv]): "to die"
