NI-MH AA and AAA batteries are better than lithium in most cases. Lithium batteries are 3.7V due to their inherent technology, but AA and AAA devices require 1.2V-1.5V. To get around this, lithium AA's have step-down circuitry in them to get to 1.5V, and that circuitry essentially drains the batteries even while they're not in use. On top of that, that circuitry generates quite a bit of EMI interference, so it causes problems in sensitive electronics, like medical devices. They're better in devices with heavy use that aren't sensitive. In every other case, Ni-MH is better.
That said, these Energizer batteries are most likely terrible Chinese batteries. Eneloop and IKEA Ladda batteries are the way to go.
