Originally posted by rfortson Non-rechargeable lithium batteries will last forever (at least 1000 shots) on my K100D. CRV3's will last 1300-1400 shots and I use them for traveling.
For NiMH's I get 400-600 shots, depending on the age of the batteries. The hybrid NiMH's seem to have much better shelf life, and still give a good number of shots.
Specs are usually conservative -
1,000 shots from lithium AA sounds (and
IS) a lot -
being 50% better than spec.
But this is kind of confirmed by the reported 400-600 shots for NiMh
which is also about 50% better than spec.
However even taking these higher figures for lithium AA -
but staying with the conservative shot count for rechargeable NiMh -
we can still do the cost comparison -
Life-time shot count for NiMh
(conversatively at 300 shots per charge, and only 100 cycles)
= 30,000 shots
Lithium AA at 1,000 shots per set for 30,000 shots
needs 30 sets @ $10/set of 4
= $300....
$300 is still a substantial sum of money.......
Of course YMMV.
