It's too
bad NiMH cells can't match the size, weight, and power
density characteristics of Li-ion cells, because NiMH's have
a lot of other advantages.

What might those be? The size, weight, and power density advantages of
Li-Ion are just three of the many advantages.


The major advantages of Li-Ion a

1. Much lower self-discharge rate (except for Sanyo Eneloop NiMH
batteries)

2. Higher maximum number of charge/discharge cycles

3. Higher energy density in terms of both weight and volume

4. Far, far better low-temperature performance

5. Lower cost, when you factor in the higher energy density, and the
maximum number of charge/discharge cycles

6. Protection circuitry integral to the battery pack, rather than
integral to the camera

7. Accurate charge level indicator due to linear voltage decline
proportional to charge level

8. Lower maintenance.

9. Much better selection of higher-end cameras use Li-Ion batteries.

10. No problems with battery doors that are part of the charging
circuit (battery doors are the most often replaced part of digital
cameras).



NiMH rechargeable batteries have the following advantages over Li-Ion
rechargeable batteries:

1. Faster charging with high rate chargers

2. Ability to use disposable AA batteries if NiMH AA batteries are
discharged and no charger is available

3. Longer shelf life

Sounds like biased li-ion evangelism to me. Suit yourself.

I see, so you can't point out any inaccuracies in those statements, and
you can't point out the "a lot of other advantages" that you stated existed.
