The lithiums have a power loss curve that falls off sharply when it falls at
all. That is good for Zoomer users because the gradual fall in alkalines
quickly drops the output below what the Zoomer needs. That is also why
rechargable batteries perform so poorly in the Zoomer. Lithiums provide
longer usable power for the Zoomer. The Zoomer needs that "high, fast output."
