[Star Wars] Why didn’t Count Dooku use Force Lightning in his final duel?

In The Clone Wars series, Dooku is consistently shown to use his Force Lightning as a last resort to defeat his enemies. Notable examples are in his duels against Asajj Ventress, Savage Oppress, and even Anakin on Naboo—in each case he was seemingly on the verge it defeat before turning the tide with the Lightning. Assuming that the Lightning is as effective, why didn’t Dooku use it in his duel with Obi-Wan and Anakin over Corusaunt? Did he simply not get the chance to?

This is probably it, Anakin was pressing him hard and by tapping into his Chosen One potential and inner rage he could finally overpower Dooku with his superior strength. Anakin didn't give him the chance before cutting his hands off and having sabers at his neck.

Doubt it's a matter of Lightning being too draining, he's used it at worse times (being blinded and beaten down by Nightsisters).
