No. He stated that, while discharging an individual cell below a certain voltage will damage it, the battery management circuitry on each cell will not permit the battery to discharge past that point. It simply disconnects the battery from the circuit, which means the only leakage is chemical (self-discharge), and thus very slow.

To clarify this point: "discharge fully" =/= zero percent. You will never want to go below a certain percentage of absolute charge.

"Another error on the part of the blogger is the claim that if the cars discharge fully, the battery packs will be damaged. This is blatantly false."

"It's true that a full discharge to zero percent state of charge can potentially be damaging to a battery."
