Ah, but the pack's capacity drops as it ages. If you use 80% of the
pack's capacity for your daily commute when it is new, then your
batteries are "bad" when their capacity falls to 80% because they can no
longer make the commute. If you use 50% of the pack's capacity when new,
the batteries can still make the commute when they have aged to only
deliver 50% of original capacity. You'll get over twice the battery
life.
